Skin and coat supplements: The basics

  • Always talk to your vet first — Talk to your veterinarian to make sure these supplements are appropriate for your dog’s health.
  • Check the label — Many supplements (including those listed here) contain fish or meat flavoring, which can harm dogs with food allergies.
  • Dog supplements aren’t regulated by the FDA — But you can check for the NASC Quality Seal, which means they’ve undergone an independent quality assessment.
  • Put your pet on a high-quality diet — 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.
  • Never give your dog a human supplement — Supplements optimized for humans can contain ingredients that can harm dogs. Only give your pet supplements designed for them.

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. Look to see if they have done independent trials or have certification from NASC.

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, others are better given as a single treat.

  • Chews. Are just another soft dog treat, just with extra vitamins and minerals.
  • Tablets. Can be snuck into soft treats so your dog doesn’t suspect a thing.
  • 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 into your dog’s mouth.

Common ingredients found in skin supplements for dogs

  • Fish oil. 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 overall skin health and are essential to a dog’s health. Canine studies have found that they support cardiovascular and dermatological functions and decrease pain and inflammation caused by osteoarthritis.
  • Krill oil. Like fish oil, krill oil contains fatty acids. One study found that krill oil had more omega-3s, but more studies are needed.
  • Antioxidants. Dogs need antioxidants to fight off toxins. Natural dog-friendly foods like blueberries, blackberries, carrots, and sweet potatoes contain antioxidants.
  • B vitamins like B6 and B12. B vitamins support the development of cells and help dogs absorb protein and fat.

Does your dog need a 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 supplements above could help.

Risks for pet parents to know 

Unfortunately, dog supplements don’t have to be approved by the FDA, so not all pet supplements may be safe to take. Err on the side of caution by consulting your dog’s vet before giving your pet a new supplement. 

Our veterinarian, Dr. Erica Irish, DVM, notes that over supplementing can be a problem, especially if your dog already is getting enough nutrients in their daily diet. She says that any flavoring would throw off a dog’s skin health if they were allergic to the flavor (so be cautious if your dog has food allergies). 

And don’t forget to always check the ingredient list before starting your pooch on a supplement. 

👉 Coconut oil is often used in supplements, but it may increase the risk of pancreatitis.

Tips for choosing a coat supplement

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. 

Look for NASC approval — The NASC Quality Seal identifies products from pet companies that are dedicated to quality, vigilance, and continuous improvement. 

Knowing what your dog’s coat is telling you

A healthy dog coat looks thick and shiny (but not greasy). Here are signs to look for when your dog’s coat is telling you something’s wrong:

What causes skin problems in dogs?

A few common culprits causing skin problems include allergies and infections include:

  • 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 ingredients in their diet, most often to proteins like beef and chicken. Food allergies lead to symptoms like itchy skin and paws, skin rashes, and red eyes.
  • Fungal and bacterial infections. Infections like ringworm and yeast infections 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

Bathe and groom your dog regularly — How often you groom and bathe your dog will depend on their breed and their specific health issues. But regular grooming sessions allow you to keep them looking fresh and give you a chance to look for any changes in their health.

Speak to your vet about problems you see — “Address any skin issues with your vet as soon as possible,” says Dr. Irish. Your veterinarian will figure out what’s causing your dog’s issues and create a plan to treat the condition going forward.

Ensure you’re feeding dogs a high-quality diet — If they’re missing important vitamins and minerals, their skin and coat will show it.

Frequently asked questions

What can I add to my dog’s food for dry skin?

You can add a dose of salmon or fish oil that naturally includes omega-3 and omega-6 fatty acids to support your dog’s skin and coat. Always follow the dose recommendations on the product label.

What can you give a dog with skin problems?

If your dog is having skin problems, the best thing to give your dog is a trip to the vet’s office. Vets can diagnose what’s going on with your dog, and you can always bring photos or videos of your dog to show them.
