Why Can Dogs Eat Flaxseed Oil?

Dogs can eat flaxseed oil because it is non-toxic and contains multiple beneficial nutrients, mainly omega-3 fatty acids.

Flaxseed oil is generally safe for healthy dogs, but there are some cautions associated with its use. We will cover the benefits and potential dangers of giving your dog flaxseed oil in the next section.

Benefits/Dangers of Feeding Flaxseed Oil to Dogs

Benefits

The most important benefit of feeding flaxseed oil to dogs is the omega-3 fatty acids. These fatty acids have some anti-inflammatory properties, although potentially not as strong as with fish oil.

Omega-3 fatty acids may help treat and manage multiple medical conditions, including:
  • Arthritis
  • Allergies
  • Heart disease
  • Some types of cancer

Flaxseed oil can also help maintain skin and hair coat health.

Dangers

For healthy dogs, properly dosed flaxseed oil poses few dangers. It can cause an upset stomach, diarrhea, vomiting, and oily skin and may delay wound healing.

High amounts of flaxseed oil can trigger pancreatitis or inflammation of the pancreas.  This painful condition can be life-threatening in some cases, and dogs at high risk of pancreatitis or suffering from the chronic version should not take flaxseed oil.

How Do I Give My Dog Flaxseed Oil?

Flaxseed oil is typically available in capsule or liquid form. Liquid flaxseed oil can go bad quickly once it’s opened. You must follow the storage directions carefully, refrigerate as needed, and protect the oil from light. Capsules may be easier to dose and administer.

In the United States, supplements like flaxseed oil are not well-regulated. There’s minimal oversight or testing to ensure the flaxseed oil you buy is good quality and works as intended. However, you can ask your vet for help finding a reputable brand of flaxseed oil to give your dog.

As we mentioned, high doses of flaxseed oil can upset your dog’s stomach or cause pancreatitis. Ask your vet for help calculating the correct dose of this supplement. Flaxseed oil can be given by mouth on its own or mixed into your dog’s food.

Is Flaxseed Oil Effective?

Flaxseed oil may be beneficial for dogs with certain diseases, but it may not be as effective as other sources of fatty acids, particularly fish oil. The fatty acids in fish oils are a more potent form, which typically make them stronger anti-inflammatories for dogs.

Because of that, dogs may need to take higher doses of flaxseed oil to reap the same benefits they would get from fish oil.

Conclusion

Before starting your dog on any new food or supplement, such as flaxseed oil, discuss the situation with your veterinarian. Flaxseed oil may not be an appropriate choice for all dogs. In addition, other types of oil are more effective for your pet’s medical needs.

Fatty acids can be useful to treat numerous chronic, inflammatory conditions, but they are rarely used alone. Your vet is in the best position to monitor your dog’s health and prescribe the supplements and treatments they need.
