Is cod liver oil good for dogs?

Yes. Cod liver oil is a rich source of the omega-3 fatty acids EPA and DHA, which support healthy skin, a shiny coat and normal joint function. Give it daily, in the right amount for your dog's weight.

What are the benefits of cod liver oil for dogs?

The omega-3 fatty acids in cod liver oil support:

  • Skin and coat: helps keep skin healthy and the coat glossy, especially in dry winter months
  • Joints: supports normal joint function and mobility
  • Brain and eyes: DHA supports normal brain and eye function
  • Overall health: supports the immune system and heart health

It won't change things overnight. Give it daily for at least a few weeks before you judge the difference.

How much cod liver oil should I give my dog?

The right amount depends on your dog's weight. Our Arctic Cod Liver Oil feeding guide, per day:

Dog's weight

Daily amount

1–10kg

1 pump

11–25kg

2 pumps

26–45kg

3 pumps

Over 45kg

4 pumps

Start with half the amount for the first 7 days, then give the full amount from day 8. Mix it into their main meal.

Can cats have cod liver oil?

Yes, our Arctic Cod Liver Oil is suitable for cats from 8 weeks. Give 1 pump a day for small cats and 2 for medium or large cats, mixed into their food, starting with half the amount for the first week.

Can you give a dog too much cod liver oil?

Yes. Cod liver oil contains vitamins A and D, and too much of either can be harmful over time. Stick to the feeding guide, don't add it to another cod liver oil or vitamin supplement, and check with your vet if your dog's food already has added vitamins. Too much fish oil at once can also cause loose stools, which is why you start with half.

When to see your vet

Check with your vet before giving cod liver oil if your dog or cat is on medication, has a health condition, or already eats a supplement or food with added vitamins A and D.
