There are all kinds of nutritional supplements available for dogs, all claiming to provide different benefits. It can be hard to know which, if any, are the best ones for your dog. Your veterinarian is the best person to consult about your individual dog’s nutritional requirements but in this article, we’ll take a closer look at flaxseed oil supplements and learn just how beneficial flaxseed oil is to dogs.

What is flaxseed oil?

Flaxseed oil, sometimes referred to as flax oil or linseed oil, is the oil that is obtained from the seeds of the flax plant. The seeds are ground and pressed to release their natural oil. Flaxseed oil is used as a dietary supplement in both dogs and humans due to the high level of omega-3 fatty acid that it contains. Alpha-linolenic acid (ALA) is the main omega-3 fatty acid found in flaxseed oil and can be converted to EPA and DHA which are the active forms of this omega-3.

What are the benefits of flaxseed oil?

As already mentioned, flaxseed oil contains high levels of omega-3 fatty acids. These types of fatty acids have been shown to have anti-inflammatory properties within the body and in humans, and are often used as dietary supplements to aid in conditions such as arthritis, kidney disease, allergies, heart disease, epilepsy, and some types of cancer. 

In dogs, flaxseed oil is often used to help support healthy joints and improve mobility, as well as help to maintain a healthy coat and skin. Dog skin problems are fairly commonplace among our pets, and giving flaxseed oil could help to improve the function of the skin barrier and help to manage certain skin conditions. Flaxseed oil also contains dietary fiber which can help promote healthy digestion and prevent constipation.

Some studies suggest that flaxseed oil could help to prevent the growth of cancer cells. These studies are limited and have mostly been performed in test tubes and on laboratory animals, therefore much more research is needed before we can know whether the same is true in dogs.

Is flaxseed oil better for dogs than fish oil?

Fish oil has long been used as a health supplement for its similar benefits to flaxseed oil. Flaxseed oil is often seen by dog owners as a more appealing alternative to giving fish oil because it doesn’t have much of a smell or give dogs the same fishy-smelling breath that fish oil does!

Flaxseed oil is usually formulated into either capsules or a liquid that is given by mouth. It can be given with or without food but giving it with food can help to prevent gastrointestinal upset. It can also be safely mixed into your dog’s food, and most dogs find it palatable. Some complete & balanced dog foods already contain flaxseed oil as an ingredient so check the label before you give it as a supplement. Flaxseed oil supplements usually take several weeks to take full effect but you might see a gradual improvement over this time.

Are there any dogs who shouldn’t be given flaxseed oil?

You should always consult your veterinarian before introducing anything new into your dog’s diet, including flaxseed oil. Be sure to tell them about any other medications that your dog is receiving, including any other dietary supplements. Some medications and supplements can interact with flaxseed oil.
