One of the most dangerous threats to the health of dogs around the world is the dreaded heartworm. Most people are not even aware of the illness, until it is too late for treatment and the damage has already been done. In fact, many dog owners are not at all familiar with heartworm, how it occurs, how it progresses, and what causes it in the first place. That’s why we’ll go into all of the details every dog owner should know about heartworm. What Is Heartworm Disease in Dogs and What Causes It?Heartworm disease in dogs is caused by a parasitic worm, called Dirofilaria Immitis. These are most simply put, heartworm larvae, and are carried within mosquitos. And that’s how they are transmitted – through the bite of an infected mosquito. When a mosquito, carrying a heartworm larva, bites a dog, it immediately transmits the larvae onto the dog’s skin. This is how the heartworm enters the bloodstream, through the teeny tiny mosquito bite wound – yes, that is how incredibly small these larvae are. After this, over the course of several months, the deposited larvae mature and grow into adult worms that nest and reside within your dog’s heart, blood vessels, and lungs. Once they become adults and enter the animal’s system, these worms can really cause substantial damage to the lungs, heart, and even other organs. This damage is then manifested through visible symptoms, such as fatigue, weight loss, difficulty breathing, coughing, and – in the most extreme cases – heart failure. Heartworm needs to be treated. Otherwise, this disease can be fatal to dogs. Of course, your most common precaution is through regular use of heartworm preventatives, as well as minimizing exposure to mosquitoes or mosquito-dense areas. This can help protect your doggo from contracting a potentially deadly disease. Preventing And Treating Heartworm Disease in DogsThis being said, we need to take into account that heartworm disease won’t be common in all parts of the world equally. The disease is prevalent in parts of the world with warm or humid climates, and high populations of mosquitoes. This is not an exclusive rule, however, and the disease can occur in all parts of the world, including temperate zones. As a diligent dog owner, you should get familiar with your region and if needed, take precautionary measures. If you live in an area where there are a lot of mosquitoes, you can invest in things like mosquito repellents for dogs.
