Flax... this tiny little seed is jam-packed with controversy in the pet nutrition world. Flax is heavily marketed as a great source of Omega-3 fatty acids; which it is for humans. However, there is mixed research as to whether or not dog's can convert the Omega-3 fats in flax to EPA and DHA (the usable Omega-3 fatty acids for canines). This is where flax's bad reputation stems from, and there is some truth to it: flax is not a great choice for adding Omega-3 fatty acids to your canine's diet.
Now that we've addressed the negative, let's look at some of the other aspects of flax and the main reason why we love it. Although flax contains protein, B vitamins and other dietary minerals, we use it in our GreenSea+ daily supplement as an excellent source of fiber.
Fiber is something that should not be overlooked, especially in a raw diet; depending on how your dog processes natural foods, not all raw diets will contain enough.
We definitely do not view a small amount of flax in a canine diet as a 'filler,' and encourage it as a great supplement, as long as your canine is not relying on it for valuable Omega-3 fatty acids.

Looking to add some Omega 3s to your canine's diet? Salmon oil or ground chia are excellent sources.
