10 Best Omega-3 and Skin Supplements for Dogs With Dry, Flaky Skin
Suhail Thapa 11 min read
If you've ever run your hand along your dog's back and come away with a small snowfall of flakes, you're far from alone. Dry, flaky skin is one of the most common things dog owners notice, especially in fall and winter, when indoor heating quietly pulls moisture from the air. It can leave your dog scratching more than usual, and leave you wondering what you can do to help.
The good news is that a few thoughtful changes often go a long way, and a good dog skin and coat supplement can be one of them. In this guide, we'll share 10 options from HardyPaw that dog owners turn to, what each one brings to the bowl, and how to find the right fit for your dog.
Key Takeaways
Why Is My Dog's Skin Dry and Flaky?
Your dog's skin works hard every day. A thin protective layer of fats and cells, called the skin barrier, keeps moisture in and irritants out. When that barrier gets a little worn down, the skin can dry out and start to flake, and your dog may feel itchy and uncomfortable.
Often, it comes down to a few everyday things:
- Dry indoor air, especially during colder months.
- Bathing too often or using harsh shampoos that strip natural oils.
- A diet low in fatty acids can leave the coat dull and brittle.
- Food or environmental allergies often cause itchy skin.
- Parasites such as fleas or mites.
- Health conditions like hypothyroidism or seborrhea.
Supplements tend to help most when the cause is nutritional or when your vet recommends them as part of a broader plan. If the flaking comes with hair loss, redness, scabs, an odor, or constant scratching, it's worth a visit to the vet first to know exactly what you're dealing with.
What to Look for in a Dog Skin Supplement
With so many options on the shelf, choosing a dog skin supplement can feel overwhelming. A few things are worth knowing before you decide:
- EPA and DHA: These omega-3 fatty acids come from fish oil and are the most studied for skin and coat health.
- Omega-6 fatty acids: These help maintain the skin barrier. Some formulas pair them with omega-3s for broader support.
- PEA and zinc: Non-fish ingredients that support the skin in different ways useful for dogs with specific needs.
- Dosing by weight: Clear dosing for your dog's size makes daily use simple.
- A format your dog enjoys: Softgels, liquids, chews, or powders. The best one is the one you can give every day.
10 Best Dog Supplements for Skin and Coat
Every dog is a little different, so we've grouped these dog supplements for skin and coat by type. That way, you can head straight to the approach that feels right for you.
Fish Oil Supplements
For many dogs, fish oil is the natural place to start. It supplies EPA and DHA, the omega-3 fatty acids most closely linked to a soft coat and comfortable skin.
1. Nordic Naturals Omega-3 Pet Soft Gels
A focused fish oil for everyday coat support.
Nordic Naturals uses fish oil from wild anchovies and sardines in its softgels, providing EPA and DHA without artificial colors or flavors. It’s an option for pet owners looking to add omega-3s to their dog’s diet, particularly when coat care is a concern. Smaller dogs can get omega-3s in liquid form with Omega-3 Pet Oil for Cats & Small Breed Dogs.
Quick tip: Larger dogs can have the softgel with their meal. For smaller dogs, puncture it and drizzle the oil over their food.
2. Grizzly Wild Alaskan Salmon Oil Plus
A pump-and-pour fish oil blend for the whole household
Grizzly blends wild-caught Alaskan salmon, pollock, and whitefish oils into a liquid you add straight to meals. The pump bottle makes daily dosing quick and the fishy taste tends to win over dogs who turn their noses up at capsules. It's made for both dogs and cats, so one bottle can cover everyone at home.
Quick tip: Start with a smaller amount and work up to the label's dose for your pet's weight over a week or so giving their tummy time to adjust.
3. Triglyceride Omega Supplement
Veterinary-style fish oil, sized to your dog
Vetoquinol's Triglyceride Omega capsules provide fish oil in its natural triglyceride form, along with vitamins A, D3, and E. The line comes in separate versions for small dogs and cats, medium dogs, and large and giant dogs, making it easy to find the right dose.
Quick tip: Capsules can be given whole or punctured and squeezed onto food, whichever your dog prefers.
4. Stratford Omega-3 Fatty Acid Soft Chews
Omega-3 made easy for big dogs.
If you share your home with a gentle giant, you'll know that counting out handfuls of capsules gets old fast. Stratford's soft chews pack EPA, DHA, and vitamin E into a treat-style chew made for large and giant breeds, so daily omega-3 support feels more like a reward. They come in 90- and 150-count sizes.
Quick tip: Each chew contains about 21 calories, so count it toward your dog's daily treat allowance.
Omega-3 and Omega-6 Blends
Some dogs do well with a little extra variety. These formulas pair omega-3 with omega-6 fatty acids, which work together to support the skin barrier and help skin hold onto moisture.
5. EicosaCaps Omega 3 and 6
Two-in-one fatty acid support in a capsule
EicosaCaps contain fish oil, safflower oil, borage seed oil, vitamins E and C, and zinc. The formula is intended for dogs that need extra support for dry, itchy skin or a dull coat. The smaller capsule is for cats and dogs weighing up to 40 lbs, while the larger size is made for dogs weighing 41 to 70 lbs.
Quick tip: Offer the capsule as a treat, or open it and mix the contents into your pet's food.
6. Ultra Oil Skin & Coat Supplement
A four-oil blend for dogs and cats of every age
Ultra Oil combines hempseed, flaxseed, fish, and grapeseed oils, delivering omega-3, 6, and 9 fatty acids in a single pour. It's made for dogs and cats at every life stage, from puppies and kittens to seniors, which makes it a handy pick for busy multi-pet homes. It comes in 8-oz and 16-oz bottles.
Quick tip: Mix it into your pet's food once a day, and use the label's weight chart to find the right amount for each pet.
Beyond Fish Oil: Multi-Ingredient Skin Support
Sometimes dry skin is only part of the picture. These formulas add other ingredients for seasonal itch, sensitive skin, or all-around coat care.
7. Dr. Marty Shine & Luster
Omega-3s plus botanicals for seasonal itch
If your dog's skin seems to flare up at the same time every year, Shine & Luster may be worth a look. These chewables combine omega-3 fish oil powder with quercetin, stinging nettle leaf, plant phytosterols, and salmon cartilage, and are designed to support normal histamine levels during allergy season.
Quick tip: Many owners start a few weeks before their dog's usual allergy season, giving it time to become part of the routine.
8. Redonyl Ultra
PEA-based support for sensitive skin
Redonyl Ultra takes a different approach from fish oil. It's built around ultra-micronized PEA (palmitoylethanolamide), a naturally occurring compound that helps support the skin barrier. The soft chews contain no wheat, beef, or chicken, which is reassuring for dogs with food sensitivities. Choose the 100mg or 200mg strength based on your dog's weight.
Quick tip: Because it works differently from omega-3s, ask your vet whether pairing it with a fish oil from this list makes sense for your dog.
9. Nupro Gold All-Natural Dog Supplement
An all-around food topper for coat care
Nupro Gold is a powder you sprinkle over meals, made with Norwegian kelp, ground flaxseed, nutritional yeast, and liver, along with a range of vitamins, minerals, and omega fatty acids. It works as a broad-spectrum daily dog coat health supplement rather than a single-ingredient fish oil supplement, and it's suitable for dogs of all ages.
Quick tip: Sprinkle it over dry food or mix it with a little water to make a gravy your dog may enjoy.
Targeted Nutrient Support
10. NutriVed Zinpro Chewable Zinc Tablets
Zinc support with northern breeds in mind
Zinc plays an important role in healthy skin. Some dogs, especially northern breeds like Siberian Huskies and Alaskan Malamutes, may not absorb zinc well, which can show up as crusty, flaky patches. These roast beef- and liver-flavored chewables provide 15 mg of zinc per tablet, in the form of zinc methionine.
Quick tip: Follow the label’s weight-based dosage and check with your vet before use. Don’t combine it with other zinc supplements unless your vet recommends doing so.

Which Supplement Fits Your Dog?
You know your dog better than anyone, and the best dog skin supplement is simply the one that suits their needs and slips easily into your routine. A few starting points:
- If your dog has a dull coat and mild flaking, a simple fish oil like Nordic Naturals or Grizzly is a gentle place to begin.
- If your dog is a picky eater, a liquid such as Grizzly or Ultra Oil mixes right into meals.
- If you want precise dosing by size, the Triglyceride Omega line makes it easy.

- If dryness is accompanied by seasonal itching, consider Dr. Marty Shine & Luster or ask your vet about Redonyl Ultra.
- If you have a husky or malamute with crusty patches, ask your vet whether zinc, such as NutriVedd Zinpro, could help.
Simple Habits That Support Healthy Skin
Supplements do their best work when paired with a little everyday care. These small habits can make a real difference to how your dog's skin feels:

- Brush weekly to spread natural oils and lift dead hair.

- Make sure fresh water is always available.
Finding the Right Dog Supplements for Dry Skin

Frequently Asked Questions
Q1: What is the best dog skin and coat supplement?
Ans: There’s no single best option for every dog. Fish oil rich in EPA and DHA is the most common starting point for addressing dry, flaky skin. Dogs with sensitive or itchy skin may benefit from added ingredients like PEA. Your vet can help narrow it down.
Q2: How long do omega-3 supplements take to work for dry skin in dogs?
Ans: Most dogs need several weeks of daily use before owners notice a change. Skin cells take time to renew, so it's sensible to give a supplement for at least 1 to 2 months before judging the results. Giving it every day matters too.
Q3: Are there side effects of fish oil for dogs?
Ans: Some dogs may develop an upset stomach, loose stools, or fishy breath after taking fish oil, particularly if the amount is too high. Begin with a smaller serving and watch how your dog reacts. If your dog takes blood thinners or has had pancreatitis speak with your vet before adding fish oil to their diet.
Q4: Do dogs need skin supplements if they eat a balanced diet?
Ans: No, not necessarily. A balanced diet of dog food contains all the required fatty acids. The supplements can come in handy if your dog has dry skin, a dull coat, or a vet's diagnosis. You can always ask your vet whether your dog’s diet is adequate or if you need to add a skin supplement.
Q5: When should I see a vet about my dog's dry skin?
Ans: If your dog’s skin is still flaky after a few weeks of care, or you notice bald patches, redness, scabs, an unusual smell, or nonstop scratching, arrange a vet visit. These problems may be linked to allergies, parasites, infections or hormonal issues that supplements alone won’t fix.
Q6: Can fish oil help reduce shedding in dogs?
Ans: Fish oil may help if your dog’s shedding is related to dry skin or a dull coat. It supports skin and coat health, but won’t stop normal seasonal shedding Brushing your dog regularly and feeding a complete diet can help keep loose hair under control.
