What is Cod Liver Oil?
As the name implies, cod liver oil is extracted from the livers of codfish. It has been used for centuries as a supplement in humans, originally as a vitamin D source before fortification of other foods.
Cod liver oil contains exceptionally high levels of the omega-3 fatty acids EPA and DHA compared to regular fish oils. It also provides fat-soluble vitamins A and D.
However, due to variations in processing methods and fish sources, cod liver oil quality and purity can differ greatly between brands. Always choose reputable supplements specifically formulated for dogs.
Benefits of Cod Liver Oil for Dogs
When chosen wisely, cod liver oil offers several science-backed benefits:
- Joint health – The anti-inflammatory DHA and EPA support joints.
- Brain development – DHA nourishes the central nervous system.
- Immune function – Omega-3s enhance cell-mediated immunity.
- Heart health – EPA prevents arrhythmias and lowers blood pressure.
- Skin and coat – The oils hydrate skin and make fur shiny.

For optimal effects, combine cod liver oil with vitamin E to maximize absorption. Always pick a high quality supplement designed specifically for dogs.
