People are more concerned about their pets’ health than ever before. Just like supplements for humans have become common, supplements are now being recommended for pet dogs as well. One of these is cod liver oil — a natural supplement that is rich in omega-3 fatty acids, vitamins A and D.
But the question arises: is it safe to give this oil to dogs as well? Does it really have any benefits or can it cause some side effects? Let’s understand this topic in detail so that you can be a responsible pet parent.
What is cod liver oil?
Cod liver oil, as the name suggests, is an oil extracted from the liver of cod fish (often Atlantic cod). This supplement is given to replenish vitamins A and D in the human body and improve the health of bones, skin and eyes.
But when it comes to dogs, it should be used with some caution. The main benefit of cod liver oil is the omega-3 fatty acids it contains, such as EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid), which can be beneficial for the skin, coat, joints and brain health of dogs.
Potential Benefits of Cod Liver Oil for Dogs

If your dog has dry skin or dull hair, cod liver oil can help nourish their skin and make the coat soft and shiny.

The vitamin A and vitamin D present in cod liver oil are helpful in increasing the immunity of pets. This helps the dog fight diseases better.
- Heart and brain health
DHA and EPA are essential for brain development and heart health. These elements can protect against mental function and heart problems, especially in puppies and senior dogs.
Should cod liver oil be given to every dog?
It is not necessary to give cod liver oil to every dog. It has its benefits, but if given in the wrong quantity or without the advice of a veterinarian, it can also cause harm.
Especially for dogs whose diet is already rich in vitamins A and D, additional supplements can cause vitamin toxicity.
Potential side effects and precautions
- Excess vitamin A
Cod liver oil is high in vitamin A. If given in high amounts for a long time, it can weaken the dog’s bones, put pressure on the liver and cause lethargy. - Digestive problems
Some dogs may have diarrhea, vomiting or gas problems after taking cod liver oil. It should be given in small quantities initially and attention should be paid to the stomach reaction. - Reaction with medication
If your dog is on any other medication (such as blood thinners, steroids, etc.), cod liver oil may alter their effect. So be sure to consult a veterinarian.
How much is safe to give?
The right amount of cod liver oil depends on the dog’s weight, age, health condition and current diet. Generally:
- Small dogs (up to 10 kg) – ¼ to ½ teaspoon daily
- Medium-sized dogs (10–25 kg) – ½ to 1 teaspoon daily
- Large dogs (more than 25 kg) – 1 to 2 teaspoons daily
However, this is only a general guideline. It is better to consult your vet.
Which type of cod liver oil to choose?
