The Best Salmon Oil Supplements for Dogs

Do you have a puppy or older dog? Does your dog deal with itchy skin or food allergies? Fish oil is a great supplement to add to your dog’s diet, especially if they are young, older, or dealing with allergies.

Fish oil is a rich source of omega-3, which supports your dog’s healthy coat, heart, skin, joints, and immune system. It also soothes itchy and flaky skin. If your dog has food allergies, fish oil is an excellent addition to a limited ingredient diet to bring relief to allergy symptoms and bolster your dog’s health.

Of course, you can get too much of a good thing. The recommended dose of fish oil is about 180 milligrams for each pound your dog weighs. You may want to start with a small amount and ramp-up to the full recommended dose, especially for sensitive dogs. 

We’ve researched and reviewed the best high-quality salmon oil supplements available so all you have to do is choose one to add to your dog’s diet.
