Krill oil for dogs becomes more popular as krill oil is used more by humans. Krill oil is abundant in omega-3 fatty acids EPA and DHA bonded to phospholipids and in antioxidants such as vitamins E and astaxanthin.

The supplementation with omega-3 fatty acids is necessary for dogs because the balance of omega-6 and omega-3 fats is essential for a pet’s healthy life. Nowadays, dogs eat too many omega-6 fats from food and they cannot produce omega-3 fatty acids. So it is important for them to achieve omega-3 fatty acids from nutrition to maintain a 4-to-1 ratio of omega-6 fats to omega-3s. That’s why to determine the dosage of krill oil for dogs vets recommend to balance the intake of omega-6 essential fatty acids.


A healthy dog on a balanced diet needs near 150 mg of krill oil daily. If the dog eats too many products high in omega-6 the dosage of krill oil is raised. The products abundant in omega-6 fats are:

  • Chicken or dog food with chicken;
  • Processed food or food from human table;
  • A large amount of vegetable oils;
  • Wheat products and bread.

If the dog has some inflammation processes, arthritis or joint aches the dosage should be higher. Then a dog should receive about 1000 mg of krill oil; consult your vet for the optimal dosage.
