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.
  • Wound healing – The vitamins accelerate tissue repair.
  • Eye health – Vitamin A nurtures good vision.

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


Cod Liver Oil Dosage for Dogs

The appropriate cod liver oil dosage for dogs depends on your dog’s size and needs. Veterinarians typically recommend:

  • Small dogs under 25 lbs: 250 mg daily
  • Medium dogs 25-50 lbs: 500 mg daily
  • Large dogs over 50 lbs: 1000 mg daily

For therapeutic uses, your vet may suggest higher temporary doses in the short term.

To avoid toxicity, do not exceed the safe upper limit of vitamin A for your dog’s weight. Follow label dosing guidelines carefully and monitor effects.


Is Cod Liver Oil Safe?

When chosen well and dosed properly, cod liver oil is generally safe for dogs. However, there are a few considerations:

  • Pick treats or gel capsules to avoid mess and rancid burps.
  • Choose low-mercury sustainably sourced oils.
  • Avoid overdosing vitamin A, which can cause toxicity.
  • Introduce slowly to watch for digestive upset.
  • Use caution with dogs prone to pancreatitis or obesity.
  • Rinse your dog’s mouth out after dosing.
  • Store the oil safely out of your dog’s reach.

Talk to your vet before giving any supplement, especially if your dog takes medications or has health conditions.
