What's the best salmon oil for your dogs or cats? We asked our parent readers for their favorites. Which had flavors that were most popular? Is easy to add to a pet's food bowl? Then we tried out several brands with our own family pet. Here are the ones we recommend.

Tips & Advice on Picking Salmon Oil for Your Pet

If your veterinarian has recommended salmon oil for your dog, cat (or even ferret), there is good news: there are many choices on the market today.

Most all salmon oil for pets includes Omega-3’s although some also have tocopherols (naturally derived vitamin E to prevent spoilage), Omega-6’s or Omega-9’s and even vitamins. 

While you can still find fish oil gel caps, our readers preferred the versions in pump bottles for ease of use–so that is what we focus on here in this review.

Important tip: be sure to refrigerate your bottle of fish oil as soon as you open it to avoid spoilage. 

FYI: not all dogs and cats will be excited by the addition of a sprinkle of fish oil on their kibble, so there may be some trial and error when determining which brand to try. Some have a more fishy smell than others.

While our parent readers gave us suggestions on their favorite fish oil, we also recruited our own wonder dog here at the office to research several brands. Here’s our top choices:
