Advice From Dr. Lindsey: Benefits of Fish Oil

Table of Contents

Authored by: Dr. Lindsey, DVM

I frequently get asked if dogs can take fish oil. Yes, they can take fish oil and there are many potential benefits to it. Fish oil is rich in omega-3 fatty acids specifically EPA and DHA. These can help with supporting normal histamine responses. Fish oil can also be beneficial to a dog’s heart health, skin and coat, immune system, cognitive function in older dogs, joint health, and more.

Fish oil is frequently given as a liquid that is put on a dog’s food, but it can also be in capsule form. It can take 4-6 weeks to see an effect after starting fish oil. Side effects are rare but can include vomiting, diarrhea, or a fishy odor to the breath. When giving a fish oil supplement, it’s recommended to get one that is specifically made for dogs.  Always consult with a veterinarian prior to starting a dog on a supplement.

Pet Honesty’s Wild Alaskan Salmon oil (both the dog AND cat products) contains EPA and DHA. The Wild Caught Omega- 3 Fish oil also contains EPA and DHA as do some of the Pet Honesty chews. Ask your veterinarian if the Pet Honesty products are right for your pet.
