Fish oil vs flaxseed oil for dogs - which is better? Can one substitute the other? Is flaxseed oil beneficial to dogs? Read on to find out.
Last week a visitor to my site referred me to an article on another dog site. The article keeps touting the fact that flaxseed oil contains high quantity of Omega-3s and how much dogs can benefit from the oil. What the article fails to do is to mention all the caveats, leaving readers (including the visitor who referred me to the article) the impression that flaxseed oil is an excellent oil to be given daily to dogs.
The visitor asked me, "So can I give flaxseed oil to my dogs instead of fish oil?"
The answer is simply "No".
Here are the main reasons:
But isn't it true that Omega-3 is anti-inflammatory? If so, then flaxseed oil should be good for our dogs, right? Again, the Omega-3s that have anti-inflammatory properties are the EPA and DHA; so while the Omega-3s in fish oil are anti-inflammatory, the ALA in flaxseed oil is not.
Many holistic vets and pet nutritionists are of the opinion that flaxseed oil cannot substitute fish oil. To quote just a few of them:
"While flaxseed oil has been suggested as a substitute for fish oil, there is no evidence that it is effective when used for the same therapeutic purposes as fish oil." (Shawn Messonnier, D.V.M., author of The Allergy Solution for Dogs).
"Although flaxseed oil is often touted as a substitute for fish oil, new studies show it's not a reliable alternative and, in fact, can be harmful. According to the study published in 'American Journal of Clinical Nutrition' flaxseed oil is found very less effective against inflammatory conditions." (Paul Jacobson, Pet Food Nutritionist).
"...flaxseed oil provides limited benefits for most dogs, although it may help with dull, dry coat in some dogs... No plant oil can replace the need for fish oil (or fatty fish) in the diet." (Mary Straus, in an article published in the Whole Dog Journal, November 2012).
"In feeding experiments, dogs receiving only flaxseed oil and commercial pet food suffered from bone and skeletal problems. When fish oil replaced the flaxseed oil, these problems disappeared." (C.J. Puotinen, author of Natural Remedies for Dogs and Cats).
As you can see, on the surface, the cheaper flaxseed oil may seem like an attractive alternative to the more expensive fish oil, but if you investigate further, you will realize that it is not so simple!
It is commonly agreed that flaxseed oil can improve the coat and skin conditions of some pets.
In addition, the lignans contained in flaxseed oil may have anti-cancer benefits. In fact, one ingredient of the well-known anti-cancer food (Budwig diet) is flaxseed oil.
So yes, flaxseed oil does have some limited benefits for dogs.
