If your dog eats a diet consisting primarily of Omega-6 fats, aka heavy in grains and plant-based oils, they may need fish oil to help balance out their diet. However, if your dog eats a grain-free diet consisting of raw, grass-fed meats, supplementation probably isn’t necessary.

Either way, you’ll want to consult your vet before adding anything new to your dog’s diet.

Benefits Of Fish Oil For Dogs

There are several reasons to consider adding fish oil to your dog’s daily routine:

  • Lessens shedding
  • Adds moisture to the skin
  • Improves the coat
  • Reduces inflammation from arthritis, allergies, etc.
  • Lowers blood pressure
  • Promotes weight loss in overweight dogs
  • Improves the immune system

Fish Oil Can Improve Your Dog’s Health

One of the most common reasons for supplementing with fish oil for dogs is dry skin. Fish oil for dogs’ dry skin is a great way to get your pup’s skin feeling young and vibrant again. By giving your dog an appropriate amount of fish oil, you’ll notice a change in his appearance and overall health.

Best Salmon Oil For Dogs: Grizzly Salmon Oil

Grizzly Salmon Oil

View on Amazon

This Grizzly Salmon Oil is the best-selling fish oil for dogs on Amazon. It is 100% pure wild Alaskan salmon oil and dispenses from a pump bottle for convenience. Since it is all-natural, the color may vary from bottle to bottle. Just squirt some into your dog’s food daily and see the changes in your dog.



What’s the proper fish oil dosage for dogs? For this specific fish oil, the dosage is as follows.

Dog WeightPumps
< 12.5 pounds1/2
12.5 to 25 pounds1
25 to 50 pounds2
50 to 75 pounds3
> 75 pounds4


We suggest easing into the dosage as you add it to the diet. For example, if your dog weighs 80 pounds, don’t squirt four pumps of fish oil into his food on the first day. Try half a pump and work your way up to the full four pumps over a week or two. Talk to your vet about this.

What is krill oil? Krill Oil is another supplement that delivers more Omega-3 to your dog’s diet. It is an oil derived from shrimp-like crustaceans that whales eat. This is typically more expensive, but it has a higher absorption rate, so dogs typically need smaller amounts. The Viva Labs Krill Oil is a popular option on the market. It is in pill form and is 100% pure Antarctic Krill Oil. If you need a way to give your dog its daily dose, we suggest the Greenies Pill Pockets.
