Dog coat and skin supplements make sure your pet’s fur is shiny, soft and thick, and their skin moisturized and itch-free. Read on to learn more about how dog supplements work and which one will be the best choice for your pet’s needs.

Regardless of your pet’s hair length, his coat should be shiny and have the right texture, whether that’s wiry, smooth or fluffy. Dog coats with bald spots, thinning hair or dandruff are often a sign of an underlying health issue, or the result of an unhealthy lifestyle and inadequate grooming or hygiene. Depending on the cause of your pet’s skin and coat problems, he might also be experiencing discomfort, pain or itching that could make matters difficult for him, and these problems go far beyond the obvious factor of appearance. Needless to say, as soon as you spot something amiss with your dog’s coat and skin, whether it’s the way it feels to the touch or how it looks, you should react quickly. In addition to the treatment your vet may have determined for your pet (it will vary depending on the condition your dog has), you should make sure to boost his immune system and introduce the right kind of supplements. In addition to a healthy lifestyle that includes a quality diet and plenty of exercise, proper hygiene and dog coat and skin supplements are the best things you can do for your pet. If there’s any kind of issue with his skin or coat, these supplements will promote quicker recovery and restore thickness and shine to his fur, promoting optimal moisture levels for the skin.

Why do I need skin supplements for my dog?

A dog’s coat and skin can be affected by a range of issues. From parasitic problems such as mange or allergies, the reason for your dog’s balding, itching, dry skin or any other condition could be a number of things. That’s why it’s important to go to a vet to get a proper diagnosis. You need to eliminate potential health issues that could worsen over time without proper treatment. In most cases, dog coat and skin supplements can be a great idea to use (in addition to any medication or creams your vet gives you), as they’re designed to speed up the healing process and support your pet’s immune system. When chosen properly, dog supplements can provide relief from itchiness, restore the coat’s shine, and even make your pooch grow hair in spots where it thinned or was completely lost. Naturally, there are many different supplement formulas, so this means there are different effects, too. Dog coat and skin supplements can also support joint health or heart health, all depending on the list of ingredients.

To make sure your pooch will be getting the best type of supplement for his unique needs, we’ve put together this comprehensive buying guide. From the list of best dog coat and skin supplements to factors you need to consider before buying, you’ll find everything you need right here.

Common skin and coat conditions in dogs

Considering that the skin is the largest organ of a dog’s body, it’s no surprise that there are many issues that can affect the skin. The skin and its external layer (AKA your dog’s coat) can also be an indicator of your pet’s overall health and immune system, as there are many conditions that affect the hair and skin in the process. Here are some of the most common skin and coat conditions in dogs you should know about:

Atopic dermatitis

This type of condition is related to dog allergies: it can be a reaction to pollen, insect bites, plants or food and medication and manifests as itching, inflamed skin or rashes. Unfortunately, dog allergies are becoming a more common problem for pets nowadays, and it’s not rare to hear about pooches developing allergies to kibble or having a reaction to a flea bite, for instance. If there’s no rash, it’s certain that your pet will be itchy, which can lead to incessant scratching, biting, inflamed skin, bald spots, hot spots, etc.

Hot spots

These painful, oozing lesions are also known as acute moist dermatitis and are caused by your pet licking, chewing or scratching a spot on his body. This means that hot spots can be a result of any type of irritation that prompts your pet to react in this manner. It’s important to react quickly to stop the hot spots from spreading. If your pet continues irritating the already inflamed area, it will inevitably worsen.


Yes, dog dandruff is a real thing, and it can be caused by a number of conditions. Seborrhea is characterized by irritated flaky skin that can be either dry or oily. In some dog breeds, seborrhea is inherited. Cocker Spaniels, Bassets and Westies are breeds that often deal with dandruff due to their genetics. On the other hand, dogs can also have secondary seborrhea, which is a symptom of an underlying medical problem such as hormonal imbalance, allergies or parasites.


When hearing the name ringworm, people often think that this skin condition is caused by a parasite, but it’s actually a fungal infection. It’s characterized by the appearance of raised red rings on the skin caused by contact with an infected person, animal, or objects contaminated by the ringworm-causing fungi. Highly contagious, ringworm will make your pet’s skin scaly and inflamed and their coat brittle. It’s important to note that humans can contract this fungal infection from dogs (and vice versa) and it’s crucial to follow the right steps to avoid further contagion.


Otherwise known as hair loss, canine alopecia can be partial or complete, meaning that your pooch might lose all of his coat or have bald patches all over. It can be either gradual, with hair loss occurring little by little or acute, when your pet loses his hair (or parts of it) seemingly overnight. Alopecia is usually caused by hormonal imbalance, fungal, bacterial infections or parasites.


This skin disease can be caused by various types of mites and comes in two different forms, scabies (highly contagious among dogs) and demodex (caused by a compromised immune system). Mange presents as scaly and crusty skin that’s painful and extremely itchy, and partial or complete hair loss. This type of skin condition is usually seen in strays or neglected dogs.

Even though all of these skin and coat conditions are different both in their causes and symptoms – as well as treatment types – each could be helped with dog coat and skin supplements. The supplements might not cure your pet (that’s why it’s crucial to see a vet for the correct diagnosis and treatment), but they can help speed up the healing process by promoting hair growth and healthier skin.

What to look for in dog coat and skin supplements

Dog coat and skin supplements can really make a difference for your pet, but only if you know which one to choose. Not all supplements are equally effective and some are tailored for specific issues, so it’s important to pay attention to all the important details before choosing one for your pet. These are the most important factors to consider when buying dog coat and skin supplements:


There are so many different supplement formulas out there. Some use fish oil as an active ingredient, others hemp, colostrum or coconut oil, and some combine a few active ingredients together for increased potency. While many of these ingredients have a known beneficial effect on the skin, not all of them work the same, so it’s important to do some research before buying. The choice is yours, but be sure to have your pet’s potential food sensitivities in mind when making your selection.

Delivery method

It’s not always easy getting your pooch to take his meds, and supplements fall into the same category. If your dog is a picky eater or generally dislikes anything that reminds him of bitter or difficult-to-swallow medicine, you’ll have to get crafty to ensure they take their supplements. Luckily, they come in all kinds of forms, from liquids and powders that you can mix in your pet’s food, to flavored chewables that taste like a treat and everything in between. Of course you know your pooch the best, so choose according to his preferences.


Unfortunately, dog supplements aren’t as regulated as pet parents would want them to be, so it’s important to only buy those that have some form of safety reassurances. It could be FDA approval, the fact that they’re made from natural ingredients, or produced in the USA. Steer clear from cheap and dubious supplements that have no official confirmation that they’re safe for dog use. It’s worth spending a few bucks more if need be to make sure you’re not risking your pet’s health in any way.

How often should I give coat and skin supplements to my dog?

While this will vary depending on the kind of supplement you’re purchasing, how severe your dog’s symptoms are and whether it’s a chew, powder or oil, it’s always best to read the product’s label carefully to determine the frequency of consumption. Most supplements recommend daily doses for your pup to get the product’s full benefits.
