aquarium basics lets talk about amazon sword plants

When it comes to freshwater tanks, the Amazon Sword Plant is a fan favorite – for many reasons. Here are the basics you need to know about this tank staple.

When it comes to stocking a planted tank, you have many different options to choose from. You could go with assorted floating plants to give your tank a shaded appearance or you can go with various mosses for a natural appearance. One of the most popular aquarium plant species for freshwater tanks is the Amazon sword plant.

About the Amazon Sword Plant

The Amazon Sword plant is by far one of the most popular species of aquarium plant among freshwater hobbyists. This species is easy to grow and it produces lush green foliage that looks quite attractive in the aquarium. The Amazon Sword plant is known by the scientific name Echinodorus amazonicus and it is native to Brazil. This plant grows fairly slowly but it does get large, growing up to 1-foot 8 inches tall. Amazon Sword plants are the ideal background plant for planted tanks because they grow so tall and they propagate themselves. It is also interesting to note that Amazon Sword plants can grow partially submersed – this makes them a good addition to terrariums or ripariums as well as the traditional planted tank.

Tank Requirements and Recommendations

The Amazon Sword plant is a hardy species, which is part of what makes it so popular among aquarium hobbyists. These plants only require a moderate level of care and they grow well in moderate to strong lighting. As is true for most aquarium plants, Amazon Swords need about 10 to 12 hours of full-spectrum lighting per day. For the best growth, make sure that your lighting system offers between 2 and 4 watts of lighting per gallon – this will vary depending on the size of your aquarium. To determine how many watts per gallon a particular bulb will provide, simply divide the total number of watts by the gallon size of your aquarium. For example, a 60-watt compact fluorescent bulb would offer 3 watts per gallon in a 20-gallon tank.

In addition to lighting, Amazon Swords also require certain nutrients in the tank water. These plants grow best in loose substrate that offers plenty of iron supplementation. Your Amazon Swords will draw most of their nutrients from the tank water (particularly nitrate and phosphate) but a nutrient-rich substrate will help to maintain healthy growth. EcoComplete is an excellent option, or you can put down a layer of fluorite or laterite under your regular substrate. You may also want to fertilize your Amazon Swords occasionally with a root tab to ensure proper growth.

As far as water conditions in your planted tank, Amazon Swords are fairly adaptable. They prefer a temperature range between 72 and 82 degrees with a water hardness between 3 and 8 dKH. The ideal pH range for this species is 6.5 to 7.5. Testing your tank water on a weekly basis will be very important for checking and maintaining the proper conditions in your tank. You also need to make sure you have a strong filtration system in place in addition to performing weekly water changes to maintain high water quality in your tank. Your filter will help to remove waste products from the tank water, as will your weekly water changes.

The Amazon Sword plant is a popular species among planted tank enthusiasts, and for good reason. Not only is it brightly colored and beautiful to behold, but it is easy to find in pet stores and also fairly easy to cultivate. If you are looking for a great plant to add to your planted freshwater aquarium, consider the Amazon Sword plant.

Why Do Some Dogs Have Bad Body Odor?

Dogs are cute, no doubt about that, but most of them are not winning awards for their lovely BO – in fact, if we’re being honest, most pooches are a bit stinky. Of course, if you make sure to keep them clean with regular baths, grooming, and teeth brushing, you can eliminate or at least significantly reduce any unpleasant smell. But sometimes, even if you are very attentive about your dog’s hygiene, they can still smell a bit funky. Why does this happen? And what should you do in that case? Lastly, is there a way to prevent unpleasant body odors in your dog? Let’s try and answer all these stinky questions.Why Does My Dog Smell Bad?Are you catching a whiff of something foul whenever your dog enters the room? Are you struggling to keep them clean and smelling fresh? There could be a number of reasons why your pupper is stinky, and it is important to go over everything in order to properly address this issue. Firstly, you want to consider their hygiene. Lack of regular grooming and bathing can lead to a buildup of dirt, oils, and bacteria on a dog's skin and coat, resulting in a bad odor. Make sure you are giving your dog a regular wash or a bath, and that you are using  special shampoos that are safe for pets and smell nice.

Rover Releases the Most Popular Pet Names of 2023

Whether you’re stumped for a name for your new dog or cat, or you’re just curious to know what people are naming their pets these days, Rover has some answers for you. The company released a list of the most popular pet names of 2023, and the 11th annual Top Pet Names Report also sheds light on the inspiration behind the names.Here are some of the interesting findings that Rover shared.

Rising Pet Care Costs Lead to More Surrenders

Thanks to a rising cost of living, more people are surrendering their pets to animal shelters or abandoning them on the street. According to Shelter Animals Count, the end of 2023 saw a whopping 250,000 more pets in shelters compared to a year prior. They’ve even seen a rise in the number of purebred dogs and puppies who entered shelters, and there aren’t enough animals being adopted.  Overcrowded Shelters Around the U.S.The stats say it all, and this heartbreaking problem is found all over the United States. For example, compared to 2022, Animal Care Centers of NYC saw the number of abandoned dogs they took in go up 41%, and they’d run out of space as of the start of 2024. Tragically, the shelter also euthanized a higher number of dogs (2% more) in 2023 compared to the previous year.     Animal shelters in Kentucky, such as Franklin County Humane Society, are also struggling to keep up as they deal with more surrenders and strays. The state’s shelters are full, and they’re having a hard time because so many people are giving up their pets as a result of rising costs.The Nevada Humane Society is yet another example of a shelter that has seen a rise in pet surrenders because people are finding it harder to afford their animals or they’re finding it difficult to locate housing that will let them keep their pets. In 2023, the shelter saw a 65% increase in the number of dogs that were surrendered to them.Financial Hardship and Housing Issues Are Driving ForcesWhy are so many people giving up their pets? Financial hardship and difficulty finding places to live that are affordable and accept pets are a couple of the big reasons. Many people struggle with the rising cost of living not only for themselves but also for their pets, as everything from pet food and supplies to veterinary care has gotten more expensive.  Shelters across the United States are doing what they can to encourage people to adopt and prevent people from surrendering their pets. For example, Animal Care Centers of NYC offered pet parents help in the form of training assistance, free food, and temporary boarding, and those efforts worked to avoid nearly 3,000 surrenders in 2023.  There Are Ways You Can HelpYou can do your part to support animal shelters and pet parents that are struggling. In addition to monetary donations, you can donate pet food. Or, you can offer to foster one or more animals who are currently waiting for their forever homes. And you can adopt a pet in need of a home—you might even find shelters in your area that have discounted adoption fees as a means to help people afford their new best friend.Join the PetGuide community.

Unexpected Things That Helped Me Cope With Loss of My 17-Year-Old Cat

Getting to share your life with a pet is truly a privilege, as there’s not much that can rival the sheer joy and genuine love these little creatures bring to us. But when the time comes to say goodbye, the weight of grief can feel overwhelming. In these moments, it feels like nothing can help lighten the load we carry, but it’s crucial to remember that the journey through pet loss is a shared experience among countless others who have navigated the same emotional terrain.I recently found myself grappling with the profound loss of my beloved four-legged companion, a 17-year-old cat called Luna. Luna was not just a pet; she was a loyal friend for more than half of my life, a source of comfort during challenging times, and a bundle of joy who brightened even the gloomiest days. When Luna passed away, a void opened up in my heart, leaving me adrift in a sea of grief.

Researchers Find Genetic Links Between Human and Canine Brain Tumors

In a groundbreaking study, researchers have discovered striking similarities between the most common type of brain tumor in dogs and humans - meningioma. These findings were published in the scientific journal Acta Neuropathologica. Until now, scientists struggled to find reliable experimental models to understand the biology of and develop effective treatments for these tumors. But thanks to these newly discovered similarities, doctors will be able to use a classification system that identifies these aggressive tumors in humans and pooches.“The discovery that naturally occurring canine tumors closely resemble their human counterparts opens numerous avenues of exploring the biology of these challenging tumors,” said Dr. Akash Patel, an associate professor of neurosurgery at Baylor College of Medicine and principal investigator at the Jan and Dan Duncan Neurological Research Institute (Duncan NRI) at Texas Children’s Hospital. “It also provides opportunities for developing and studying novel treatments applicable to both humans and dogs,” he added.During the study, researchers analyzed 62 dog meningiomas from 27 breeds and found that the tumors were remarkably similar to the same kinds of tumors in humans. To this date, this is the largest study of the gene expression profiles of the canine meningioma. Others, including Dr. Jonathan Levine, a VMBS professor and the head of the Department of Small Animal Clinical Sciences (VSCS), and Dr. Tiemo Klisch, assistant professor at Baylor College of Medicine and Principal Investigator at Duncan NRI, were involved in the study along Dr. Patel. Meanwhile, assistant professor Dr. Beth Boudreau was a key collaborator. Previous work done by Levine, Boudreau, and others at VMBS, which found similarities between gliomas - the second most common type of brain tumors - in humans and dogs, was instrumental for Patel’s study. “We ended up agreeing to provide Patel with canine tumor samples we had worked years and years to achieve, to see if he could isolate the RNA, which is not always easy to do,” said Levine, in a statement. “He was able to produce this very robust data set that showed a similar pattern structure to human tumors. Our team also provided Dr. Patel with key clinical outcome data, including responses to certain treatments.”Now that the researchers have found a link between brain tumors in humans and dogs they hope to establish clinical trials to continue their research. Setting up this type of clinical trial can take several years of planning and requires funding.“We are really interested in creating wins for both human and animal medicine,” said Levine. “For example, we hope to give dog owners access to therapy that’s not available anywhere else in the world through clinical trials. At the same time, that information will also inform the next step of human trials.”As it happens, another group of researchers from the University of California, Davis, conducted a similar study with matching results about meningioma in humans and dogs. This study was also published in the scientific journal Acta Neuropathologica.Now, the two research groups plan to collaborate in the future and share their findings to develop treatment options for both human and canine brain tumors. “If we do one trial, we’d be able to enroll patients a lot more quickly, which would make it easier to get larger data sets resulting in stronger findings. So we have a lot of interest in doing a collaborative trial,” added Levine. “We really see the team out in California as potential partners.” Thanks to this groundbreaking research, scientists now have a better understanding of brain tumors and are one step closer to developing life-saving treatments for both humans and dogs. Join the PetGuide community.

How Acupuncture Can Help Cats and Dogs

Acupuncture is a part of Traditional Chinese Medicine (TCM), and it can be used on people and pets to address a range of conditions. By balancing the flow of energy in the body, this technique can help reduce or resolve symptoms in a natural way.Many people have used acupuncture for their pets and achieved incredible results. But, like anything else, it might not be right for all pets or all conditions. And working with a qualified veterinarian who’s certified in pet acupuncture is key.Read on to learn more about acupuncture for cats and dogs.What Is Acupuncture for Dogs and Cats?In acupuncture, fine needles are placed in the skin on certain points throughout the body, referred to as acupuncture points or acupoints, in order to do things like restore energetic balance, reduce pain and inflammation, and support healthy blood flow. Based on your pet’s symptoms and condition, an acupuncturist will know where to insert the needles to get positive results.The needles shouldn’t cause any discomfort for your pet. In fact, pet parents often state that their animals become relaxed during their acupuncture sessions.Types of Pet AcupunctureThere are a few types of pet acupuncture, and an acupuncturist will determine which is best for your dog or cat.Dry needle acupuncture is the type of acupuncture that you’re likely familiar with. However, instead of using needles, acupuncturists can simply apply pressure to specific points on a pet’s body to support healing—this is known as acupressure.Other options include electroacupuncture, which combines the use of needles with an electric current, and laser acupuncture, which uses a cold laser to stimulate acupuncture points. The Benefits of Acupuncture for PetsAcupuncture can provide a host of benefits to pets when done correctly and by the right professional. As always, it’s wise to discuss this healing technique with your veterinarian to figure out if it’s appropriate for your canine or feline. And it’s important to discuss the potential risks or drawbacks before deciding if you want to try it.Some of the conditions that may be treated with the help of acupuncture include:Arthritis and joint problemsAcupuncture can be used to help relieve discomfort and pain associated with various conditions. If your pet has been diagnosed with arthritis or hip dysplasia, if they’ve been injured and are dealing with pain, or even if they’re having pain after a procedure, acupuncture might be a good treatment for reducing inflammation and improving mobility.In addition to acupuncture treatments, you can also help your pet feel more comfortable by using a heated bed like the K&H Thermo-Snuggle Cup Heated Cat Bed, which can also work well for small dogs. This product is machine washable and features soft fleece that your companion will love snuggling into. Its circular shape ensures your furry friend will feel nice and secure. Plus, you can use the removable heater to help alleviate discomfort and keep them warm while they relax or nap. 

A Pennsylvania Dog Shocked Its Owners After Eating $4000 in Cash

A Pittsburg couple was shocked to discover that their dog Cecil decided to have the most expensive snack of his life, after wolfing down $4,000 in cash. According to Cecil’s owners, Clayton and Carrie Law, the seven-year-old goldendoodle is a well-behaved boy who has never really done anything bad before. The couple had withdrawn cash to do a home improvement project, but Cecil had other plans for the envelope full of money. Less than 30 minutes later, Cecil was caught devouring thousands of dollars. “I walked back into the room and then all this cash was on the ground. He’s just like this, standing there, and I’m like oh my gosh, he ate some of this money and was in shock. I yelled to Carrie ‘He ate the money, he ate the $4,000,’” said Clayton Law to CBS News. After the initial shock, the couple discovered that Cecil ate a lot of the bills, but that some were still on the floor, albeit torn up and chewed into pieces. Carrie and Clayton describe their pooch as laid back, weird, funny, and almost human-like, and say that he is typically more of a snuggly couch potato. “He doesn’t do many dog things, he doesn’t chew furniture or clothing, that’s why we were extra shocked when he decided to do this,” said Clayton Law. “He has never in his life tried to get anything from the counter, even coffee table. We could leave dinner and go to the kitchen and grab wine, and he would not touch the food, and he just doesn’t care. He just took this opportunity and ran with it,” said Carrie Law. Once the initial shock passed, the couple contacted their vet to see if the dog needed any treatment. Given the goldendoodle’s size, there was no risk of bowel obstruction and he only needed to be monitored at home. At first, Cecil seemed fine, but in the middle of the night, the Laws were awoken by the sound every dog owner knows - the retching of their dog about to vomit. “When you hear that, you immediately just react, so I jumped out of bed and just made sure that he didn’t throw up anywhere,” said Clayton. “And then I went to pick it up… and I realized there’s a lot of like half eaten and $100 bills and $50 bills here.”That night marked the start of the Law’s unfortunate mission of sifting through their dog’s vomit and poop in an attempt to recover some of their money. Luckily, the couple was able to piece together most of the bills after carefully washing and sorting all the pieces back together. “There we are at the utility sink washing this shitty money, yelling ‘Yay! Yes! We got one!’ It smelled so bad,” Carries confessed. After piecing together as many bills as they could salvage, the couple managed to recoup $3,550. According to Carrie, the bank was really nice about it and told them that these things happen all the time. “They said it actually happens quite a bit because money just picks up so many scents, especially if it’s used in the food industry. I guess dogs pick up on that - they have such a good sense of smell - and something about it just drove him crazy.”Almost a month after the incident, Cecil is doing fine and is still a good boy. Join the PetGuide community.

Stray Dog Becomes Surrogate for Abandoned Puppies at Texas Shelter

A stray Great Pyrenees dog, found wandering the streets of Fort Bend County, Texas, became a surrogate mother to a litter of six abandoned puppies.In late October, a concerned citizen found an abandoned litter of puppies. After failing to locate the pups’ mother in the surrounding area, the person brought the puppies to Fort Bend County Animal Services. “They were tiny, needing immediate bottle feeding and care, they were just about a week to 10 days old,” said Rene Vasquez, the director of Fort Bend County Animal Services, to PEOPLE.Although the puppies arrived at the shelter in good condition, they were starving and needed nourishment ASAP. The Fort Bening County Animal Services took to social media to look for fosters to take in the puppies and provide them with around-the-clock bottle feedings. Around the same time, another local found a stray Great Pyrenees, named Nova, who was full of milk. While it was clear that Nova had a litter recently, her puppies were nowhere to be found. The woman who found Nova saw the shelter’s online call for help and decided to contact them with a different idea. Instead of using volunteers to do the bottle feedings, she suggested bringing Nova by to see if the dog would accept to nurse the puppies. The shelter loved this idea and decided to give Nova a chance. A few seconds after Nova met the puppies it became apparent that the shelter made the right decision. “Nova was so happy to see the puppies! She took to them right away, and they were very happy to have a mama and food,” Vasquez shared. Although the abandoned puppies aren’t Nova’s biological litter, she accepted them as if they were her own. Acting like a true momma, Nova quickly allowed the pups to nurse and cuddle close to her for warmth. Thanks to Nova’s maternal instincts the puppies are doing well and growing quickly.“We were so happy that Nova was able to step up and be a mom for them. Sometimes, it is difficult to find bottle feeders and fosters for when the puppies or kittens are so little, so to have a nursing mom available to accept the babies is definitely a good day,” said Vasquez. Nova and the puppies, five boys and one girl, are currently living in a foster home. The fosters caring for the four-legged bunch plan to adopt Nova once the puppies are weaned. “The puppies will stay with Nova until they are weaned, and then we will start looking for homes for them. They will also be vaccinated, microchipped, and fixed before going to their forever homes,” the shelter’s director added. The case of Nova and her adopted litter has a happy ending, but not all stories end on a positive note. “As an industry, we are facing a real crisis in animal welfare across the country with an abundance of stray animals and not enough adopters or fosters to help the overcrowded shelters and rescues. Nova and her puppies illustrate the importance of spaying and neutering,” said the Fort Bend County Animal Services director.Shelters around the country are struggling to take in new animals due to a lack of forever homes and overcrowding. Each year, millions of pets end up in shelters across the nation, most of which are never adopted into a forever home. If you’re looking for a four-legged companion, visit your local shelter or rescue organization to see which of their residents would make a perfect addition to your home. Join the PetGuide community.

Scientists Finally Know Why Cats Love Tuna So Much

No food is more synonymous with cats than tuna. Even the pickiest of cats can’t resist the tuna’s fishy flavor. Finally, scientists have learned why cats love tuna so much. In the study published in the journal Chemical Sense, scientists report that cats, like humans, have receptors needed to detect umami flavor. Along with sweet, sour, bitter, and salty, umami is one of the five basic tastes.Umami seems to be the cats’ favorite flavor. Considering that umami gives food a deep and savory meaty aroma, it’s no surprise that an obligate carnivore like a cat would prefer it over all other flavors.The research team also found that cats’ taste receptors bind to two chemicals found in high concentrations in tuna. These chemicals boost the umami flavor, making cats obsessed with tuna. “This is an important study that will help us better understand the preferences of our familiar pers,” says Yasuka Toda, a molecular biologist at Meiji University. According to Toda, this study could help cat food manufacturers create healthier food and more palatable medication for cats. Previous studies showed that cats have a unique palate. Cats can’t taste sugar, because their sweet receptor gene is dysfunctional. Scientists believe that felines lose the ability to taste sweeteners and carbs because they don’t need these macronutrients to survive. Cats also have fewer bitter flavor receptors than humans. This trait is commonly seen in obligated carnivores. “Since discovering that cats don’t have a functional sweet taste receptor, we did wonder what they would respond to instead,” study lead author Scott McGrane, a sensory science expert at Waltham Petcare Science Institute, told Live Science. Humans and other animals possess two genes - Tas1r1 and Tas1r3 that work together to detect umami flavor. Previous research has shown that cats express the umami-related Tas1r3 gene in their taste buds, but it was unclear whether they possess both genes needed to detect umami flavor. The research team led by McGrane discovered that cats expressed both Tas1r1 and Tas1r3 genes in their taste buds. To learn this, the scientist biopsied the tongue of a six-year-old male cat that had been euthanized for health reasons unrelated to this study. However, a closer look at the protein sequences encoded by these genes showed that they are very different from human genes. As it turned out, the main amino acids that activate umami flavor in people - glutamic and aspartic acid - were mutated in cats. “So I began thinking, maybe cats can’t taste umami,” said McGrane. But, as it turned out, amino acids don’t bind to the cat umami receptor alone. Nucleotides, which are common in meat and yeast, bind to the cat receptor and glutamic and aspartic acid then have an enhancing effect. “That’s the exact opposite of what we see in people,” explained McGrane. Cats love tuna because it contains the nucleotide inosine monophosphate. Tuna also contains large quantities of L-histidine, an essential amino acid for cats, that enhances umami flavor. “The L-histidine content of tuna is much higher than of other fish species and meat sources.”These new findings could be used for the development of tastier cat food and pharmaceuticals. Although cat food manufacturers already knew that cats prefer meaty flavors, they now have much more details about the compounds they can start working with. It’s essential for manufacturers to ensure that animals want to eat the food they formulate and find it appealing. “I think umami is as important for cats as sweet is for humans,” said Toda. Dogs, she explained, can taste both sweet and umami, which may explain why they’re not such fussy eaters. Join the PetGuide community.

Is Aquarium Salt Safe for Plants?

All those in love with the fascinating world of aquatics know how sensitive and (sometimes) demanding pet fish and  aquarium plants are. The aquarium plant life in particular can be very vulnerable, reacting to the smallest changes in the tank’s environment. Naturally, this begs the question: could adding salt to your tank potentially kill its plant life? Or is salt beneficial for your aquarium’s flora? These are the questions that need to be answered carefully, as there are different types of salt used, and not all have the same effects on the many different aquarium plants. Let’s dive deeper into the topic!Is Aquarium Salt Safe for Plants? Aquarium salt, when used properly, has many uses in an aquarium setting. It can help with certain issues like treating fish diseases and promoting electrolyte balance in fish. But what about plants? The key to using salt with aquarium plants is moderation and research. There are different types of salt on the market, so you should inquire about their properties and possible effects on fish and plants. Secondly, always use it in moderation. When used in the right amounts, salt can be beneficial. However, the excessive use of salt can be harmful to plants, as it can disrupt their osmotic balance and lead to dehydration or nutrient imbalances. In fact, put too much of it, and you can kill all the plants AND the fish in the tank!But what is the osmotic balance? Like all living organisms, plants maintain a delicate balance of water and salts within their cells. When exposed to high concentrations of salt, such as those found in aquarium salt products, plants can experience “osmotic stress”. This stress occurs because the salt outside the plant's roots creates a higher concentration of solutes in the soil than inside the plant cells. As a result, water is drawn out of the plant, leading to dehydration and potential damage – and even death.Excessive salt in the aquarium soil can also interfere with a plant's ability to absorb essential nutrients. Sodium ions, which are a component of salt, can compete with other positively charged ions like potassium, calcium, and magnesium that plants need for healthy growth. This competition can disrupt nutrient uptake and lead to deficiencies, even if those nutrients are present in the soil.Another confusing factor is that some aquarium plants are much more tolerant than others. Halophytes, for example, are plants that have evolved to thrive in saline environments and can withstand higher levels of salt in the soil and water. However, most freshwater aquarium plants are not adapted to high-salt conditions and can suffer greatly when aquarium salt is introduced to the tank. You should also consider the types of salt available. Sea salt, for example, is much different and more complex than ordinary table salt. It contains sodium chloride, and minerals like potassium, zinc, and calcium. As such, it is only suitable for use in aquariums that have marine fish and  invertebrates, and plants naturally occurring in salt waters. 

After 11 Long Years, a Cat That Was Presumed Dead Returns Home

Sometimes, miracles can truly happen when you least expect it! And if a pet story can be considered a real life miracle, it’s the one about Toby, a family cat that - it would seem - lived a life of great adventure. In 2012, Toby, the now 14-year-old cat of the Allan family from Warwickshire, suddenly disappeared after the family moved to a new house. It was a heartbreaking event for the entire family, but their pet was nowhere to be found. After many attempts to locate their cat, they simply had to come to terms with the fact that old Toby was lost, and presumably dead. But this week, after 11 long years, Toby was returned to the Allan family by a local woman. The lady checked the cat’s microchip and was quick to get in touch with Coventry Cats Protection."I never thought in a million years I’d see him again," said owner Justine Allan. "Toby was collected and will no longer have to scavenge for food and sleep in a cold bin store," added the Coventry charity co-ordinator Wendy Harris.Toby suddenly went missing in a chilly December in 2012, after the Allan family moved from Galley Common in Nuneaton, to their new residence at Long Shoot."[My son Charlie] was about 12 when Toby went missing, and he was heartbroken when we realized he probably wasn’t coming back," said Mrs Allan for  Yahoo "The Long Shoot is a notoriously busy road, we just assumed the worst had happened and thought he had been run over.”But almost a decade later, just 5 miles away a local Bedworth lady got in touch with Cats Protection, believing that a stray cat she was feeding was pregnant. A volunteer with the charity went out to investigate, a microchip scanner in tow. "It turned out, not only did it have a chip, but that he was a neutered male named Toby, rather than female as originally believed," said Ms. Harris.Blazingly fast, the charity managed to trace the details of the Allan family on their database, and got in touch to share the splendid news – their missing feline friend was re-discovered!Initially in complete shock, after 11 years, the Allan family rejoiced and celebrated and quickly went out to pick up their long-lost pet. During those 11 years, the family welcomed another pet into their home, a King Charles Cavalier named Bernie. But even so, Toby fits right back into the family dynamic. As if he wasn’t missing for more than a decade!

Study Finds That Pet Owners Experience Slower Cognitive Decline

Studies have shown that owning a pet can promote physical health in older people, but there isn’t enough research on the impact of dogs, cats, and other pets on cognitive function. As people age, their cognitive functions and memory decline. Although all people experience some level of cognitive decline as they age, some individuals can maintain good cognitive function well into advanced age. In contrast, others experience a sharp cognitive decline early on. Researchers have suggested various strategies to slow cognitive decline, from treating sleep apnea to improving diet and increasing exercise. In a new study, a team of researchers has set to discover whether pets, mainly cats and dogs, may help slow down cognitive decline in seniors.Scientists from the University of Maryland wanted to examine the link between pet ownership and changes in cognitive function of community-dwelling seniors. The goal of this study was to determine whether pet owners experience slower cognitive decline. They also wanted to see if there’s any difference if the pet is a dog or a cat, and whether dog walking might reduce the rate of cognitive decline. The team analyzed data from the Baltimore Longitudinal Study of Aging, the longest-running study of aging in the U.S. Using the data from this study, enabled the research team to analyze the cognitive tests of 637 participants ages between 51 and 101.Of the participants, nearly one-third owned pets, with 11% owning cats and 13% owning dogs. Among dog owners, 69% reported walking their dogs regularly. Results revealed that during 10 years, all participants experienced a decline in cognitive functions as they aged. However, decline was slower in pet owners, compared to non-pet owners. Interestingly, the slower decline was more evident in some but not all tests used to determine cognitive function. Additionally, the results also showed some variations between cat and dog owners. For example, researchers noted that dog owners who walked their dogs regularly experienced even slower cognitive decline than cat owners and dog owners who didn’t walk their pets.This finding showcases just how beneficial walking your pooch can be for your overall health. Owning a dog can increase physical activity, as they need to be taken out for regular walks and daily exercise, which is known to be beneficial for health. “Older adult pet owners experienced less decline in cognitive function as they aged, after considering both their pre-existing health and age,” the study authors said.“Memory, executive function, language function, psychomotor speed, and processing speed deteriorated less over 10 years among pet owners than among non-owners and among dog owners than non-owners.”“Cat owners experienced less deterioration in memory and language function. Dog walking was also associated with slower deterioration in cognitive functioning.”Numerous other studies have shown that pets can provide social support and that interacting with a cat or dog can lower heart rate and blood pressure.This study is important for the scientific understanding of factors linked with cognitive decline. However, this study isn’t without limitations. Firstly, the study doesn’t allow any cause-and-effect conclusions to be made. Secondly, the study sample consisted of people with higher socioeconomic status and above-average cognitive abilities for their age. “Policymakers could use these findings to support the inclusion of pets in care plans, designing housing and neighborhoods for seniors that are friendly for dog walking and developing programs to support pet ownership and care for older adults’ pets while they are temporarily unable to do so,” concluded the authors of the study. Join the PetGuide community.

Animal Shelter Has Clever Way to Fundraise for Valentine’s Day

Valentine’s Day is for celebrating love, but for some, it can be a reminder of failed relationships. If you’re still feeling bitter towards an ex, you can now take that resentment and transform it into something positive, thanks to a clever fundraiser being run by an animal shelter in New Jersey.“Neuter Your Ex” and Help Stray Cats This Valentine’s Day Homeward Bound Pet Adoption Center in Blackwood, NJ has come up with a funny way to raise much-needed funds for stray cats this Valentine’s Day. The campaign is called Neuter Your Ex for Valentine’s Day, and its slogan is “Because some things shouldn’t breed.”It’s simple: when you donate $50 to Homeward Bound, they’ll name a feral cat after your ex and then neuter or spay the kitty before releasing them back to their outdoor colony. If you’re familiar with trap-neuter-return, also known as TNR, then you already know how this works—cats who aren’t adoptable are allowed to live out their lives outdoors, but because they’ve been neutered or spayed, they can’t reproduce and, therefore, won’t contribute to the overpopulation problem.A Big Success So FarThis campaign is already a hit. Multiple news outlets have reported on it, so word has spread far and wide. The shelter states that they’ve received a lot of names (they’ve gotten so many that it will take months to use all of them). And donations have come from around the United States and other countries, such as the United Kingdom and Australia. Want to Help? Here’s HowIf you want to make a donation towards this worthy cause, you can fill out the form here, provide your ex’s first name or a nickname, and make a one-time or monthly payment to support the shelter’s TNR efforts. If you have questions, you can reach out to Homeward Bound Pet Adoption Center. Their recent Instagram post provides answers to some frequently asked questions about the campaign, so you can check that out as well.  Keep an eye on Homeward Bound’s Instagram to see photos of the cats that end up benefiting from this Valentine’s Day fundraiser.Join the PetGuide community.
