Dr. Irish is a big fan of Native Pet Omega Oil. She really likes that it’s made with limited ingredients, without any unnecessary fluff or fillers.

Our research process
Why you should trust our reviews
- Dr. Erica Irish helped us formulate this list — Our veterinarian reviewed each and every product on this list herself to check for safety, effectiveness, and overall benefits. She helped us rank each of these supplements and shared her likes and dislikes about each one.
- We ordered and paid for these products — None of these supplements were sponsored or gifted to us. Instead, our team absorbed the cost in order to be able to give each one an impartial review.
- We sent them off with our product researcher to test in the field — We’re so fortunate to have Sara Ondrako, our very own product review expert, on our team. We sent each of these supplements to her to review with her dogs.
How we picked
We searched high and low for the most popular skin and coat supplements for dogs on marketplaces such as Amazon and Chewy. Then, with the help of Dr. Irish, we narrowed down our list, focusing on safe ingredients and products from reputable brands. Once our veterinarian and product reviewer had a chance to test each product, they helped us establish which one had the highest ranking in all of our established criteria. This product is the one we lovingly referred to as our “top pick.”

*price at the time of our review
How we tested these products
We worked with Dr. Irish, our veterinarian, and Sara, our expert product reviewer, to determine the most important criteria for skin and coat supplements for dogs. We ultimately decided on the following:
- Ingredients. We examined the ingredients in these supplements to identify exactly what made them beneficial to your dog’s skin and coat health.
- Consistency. It’s helpful to have different options to try. We tested products with three different consistencies: chews, liquid, and powder.
- Palatability. Of course taste matters! While you know that these products are all skin and coat supplements, your doggo thinks it’s treat time every time they get to enjoy the delicious flavor!
- Smell. Dogs rely on their sense of smell for so many things, so if something smells off-putting to them, they’re not going to want to eat it. The dogs really liked the way each of these supplements smelled.
- Packaging. Freshness is important, and the way a product is packaged makes a difference.
- Safety. We take safety seriously, so this criterion was a must. We wanted to make sure these supplements didn’t contain any toxic ingredients.
What else should pet parents consider?
Does your dog need a coat and skin supplement?
Most of the time, your dog probably doesn’t need a skin supplement. As long as your healthy pup is eating a well-balanced diet of high-quality commercial dog food, they’re probably getting all the nutrients they need.
But, if your dog has vitamin deficiencies or health conditions, skin supplements can give them an extra boost to heal their dry skin and dull coat. If your dog’s coat looks dull, consult your veterinarian to determine if one of the above supplements could help.
How to use skin supplements and what to expect
For dogs with persistent skin issues, it’s best to give them supplements daily. These supplements are also most effective for pets with mild skin and coat issues, like occasional irritation or a dull coat during certain times of the year. If your dog has chronic skin issues like a rash or wound that isn’t getting better, talk with your veterinarian. They’ll help conduct the necessary tests to rule out environmental allergies, food allergies, bacterial infections, and more.
A well-rounded diet is still key
Supplements are one way to improve your dog’s skin and coat. But dogs need to regularly eat nutritious meals to stay in tip-top shape.
Dog supplements aren’t regulated by the FDA
No organization oversees the pet supplement market, so pet parents need to be diligent. Only buy from reputable companies and stay far away from any that claim to “cure” your dog’s ailments. You can also check for the NASC Quality Seal, which means they’ve undergone an independent quality assessment.
Types of doggie skin supplements
There are different types of skin and coat supplements out there to suit your dog’s preferences. Some are easy to mix into food, while others are better given as a single treat.
- Chews. Supplement chews are just another soft dog treat, just with extra vitamins and minerals.
- Tablets. This option can be snuck into soft treats so your dog doesn’t suspect a thing.
- Powders. Powders are easy to mix into kibble, food, and water.
- Liquids. Liquid supplements can be dribbled onto kibble, or you can use a dropper to place a few drops in your dog’s mouth.
Common ingredients found in skin supplements for dogs
Some of the most common ingredients found in skin and coat supplements for pups are listed below. Read on for additional information about the benefits of each for your dog:
Fish oil is a popular ingredient in most skin supplements because it’s loaded with omega-3 fatty acids. Omega-3s naturally aid and support the skin and are essential to a dog’s health. Canine studies have found that they support cardiovascular and dermatological functions and even decrease pain and inflammation caused by osteoarthritis.
Like fish oil, krill oil contains fatty acids and is another option to try.
Antioxidants are natural molecules that dogs need to fight off toxins and are found in most skin and coat supplements. They offer many benefits to our canine friends, including healthy skin and a shiny coat. Many dog-friendly foods, like blueberries, blackberries, carrots, and sweet potatoes, contain antioxidants.
B vitamins like B6 and B12
Sometimes it’s necessary for pet parents to supplement their doggo’s diet to ensure optimal health. Dogs can’t synthesize vitamin B, which supports the development of cells and helps dogs absorb protein and fat. Vitamin B benefits the heart and immune system, and also helps with skin health, relieving itchiness for dogs that suffer from allergies or dry skin.
Vitamin E is an antioxidant that’s found in most skin and coat supplements. Vitamin E not only relieves itchiness but also helps your pup to look and feel like they’ve just spent a day at the salon. Salmon is rich in vitamin E, and, as you may have noticed, salmon and salmon oil are top ingredients in many of our chosen skin and coat supplements.
Yummy sunflower seeds and sweet potatoes are good sources of biotin, a very important B vitamin. Skin and coat supplements often include biotin because it produces amazing results for dogs that suffer from allergies. It helps dogs to synthesize fatty acids and works to relieve many skin conditions, including a dull coat, brittle hair, loss of hair, scaly skin, itchiness, and dermatitis.
Ingredients to avoid
There are many beneficial ingredients that promote healthy skin that are great for dogs, but there are also a couple that should be avoided. Just because they’re in a product made for dogs, doesn’t guarantee they’re safe.
- Coconut oil. While coconut oil is often used in supplements, it may increase your dog’s risk of developing pancreatitis, making this an ingredient to avoid when picking a supplement for your pup.
- Xylitol. Xylitol should be avoided at all costs, as it’s highly toxic to dogs. Surprisingly, xylitol sometimes sneaks past us in foods like peanut butter because the label says “naturally sweetened.” Even very small amounts can be extremely harmful to pups.
Tips for choosing a coat supplement
Choosing the right supplement for your pup is no easy task. Below are some vet-approved tips and tricks to help:
Always consult your vet — This should always be your first step before you introduce something new into your dog’s diet.
Less is more — The simpler the supplement, the better. Limited ingredients help to ensure your pet is getting all of the nutrients they need, and none of the filler and byproducts they don’t.
Look for NASC approval — The NASC Quality Seal identifies products from pet companies that are dedicated to quality, vigilance, and continuous improvement.
Keep in mind that oversupplementing is possible — Dr. Irish notes that oversupplementing can be a problem, especially if your dog is already getting enough nutrients in their daily diet.
Check labels closely — Don’t forget to always check the ingredient list before starting your pooch on a supplement, especially if your dog has food allergies. Any food allergy can throw off a dog’s skin health.
How to know what your dog’s coat is telling you
What causes skin problems in dogs?
- Dandruff. Most of the time, dandruff is caused by seasonal changes, but it can also be a sign of underlying health conditions like parasites and allergies.
- Seasonal allergies. Your pooch can have allergies in response to seasonal changes, like fresh grass and tree pollen. Seasonal allergies are another type of environmental allergy.
- Food allergies. Dogs are sometimes allergic to proteins like beef and chicken. Food allergies lead to symptoms like itchy skin and paws, rashes, and red eyes.
- Fungal and bacterial infections. Infections like ringworm cause all kinds of skin problems in dogs and need to be treated by a veterinarian.
- Flea allergies. Flea saliva causes intense itchiness in dogs, and some dogs will experience a severe allergic reaction. A dog can show an allergic reaction after just one flea bite.
- A lack of mental stimulation or stress. Sometimes dogs will excessively lick or chew themselves because they’re stressed or bored.
Other ways to help your dog’s coat shine
Incorporating a skin and coat supplement into your pup’s diet is one way to help improve the luster of their coat, but it’s not the only thing you can do to help. Some additional tactics to try are listed below:
Bathe and groom your dog regularly — How often you groom and bathe your dog will depend on their breed and overall health, but regular grooming sessions allow you to keep them looking and feeling fresh.
Speak to your vet about problems you see — Address skin issues with your vet as soon as possible. Your veterinarian will figure out what’s causing your dog’s skin problem and create a plan to treat it.
Ensure you’re feeding your dog a high-quality diet — If your dog is missing important vitamins and minerals, their skin and coat will show it.

Frequently asked questions
What supplement is good for my dog’s skin and coat?
Since each pooch has individual needs, what works for one may not work for another. A great way to determine which supplement is best for your dog is to identify their specific issues and then choose a supplement that targets that problem.
How can I improve my dog’s skin and coat?
From brushing and bathing to flea and tick prevention, there are lots of ways to improve your dog’s skin and coat. Proper nutrition is also very important for the overall health of your fur baby. Sometimes dogs need extra help to combat allergies and dry skin, and that’s where supplements can really help.
What supplements do vets recommend for dogs?
Glucosamine (for joints), fish oil (for skin), antioxidants (for overall health), and probiotics (for intestinal health) are among the most popular supplements for our canine companions.
Does salmon oil improve a dog’s coat?
Salmon oil is an incredible supplement for your pupper. It’s rich in healthful omega-3 and omega-6 fatty acids, which help to provide relief from allergies and itching while promoting a soft, shiny coat. It’s no wonder so many of the supplements on our list contain this amazing ingredient!
Can dogs take biotin?
Biotin is not only safe for dogs but also very good for them! It’s a water-soluble vitamin, which means it absorbs into the body once it dissolves. It’s important to note that daily supplements are necessary. Biotin offers many benefits for our furry friends, including healthy skin and hair, as well as liver, brain, and nervous system health.
