Flaxseed

Also appears on labels as: flax, whole flaxseed, ground flaxseed, organic flaxseed, flaxseed meal, organic flaxseed meal

Small oilseeds rich in alpha-linolenic acid, a short-chain omega-3, plus soluble fiber and lignans.

Watched ingredients get highlighted on every product panel you open.

Where it comes from
Oilseed farms, mostly Canadian.
Why it's in the product
Omega-3 fatty acids for skin and coat, and fiber.
Safety and toxicity
Safe. One honest limitation: dogs convert plant ALA to the useful long-chain EPA and DHA very inefficiently, and cats barely at all. Flax is not a substitute for fish oil if omega-3 is the reason you picked the food.

General reference, not veterinary advice. Dose, breed, and existing conditions change the answer, so talk to your vet before changing what your pet eats. Think we got this wrong? Tell us and we log it publicly.
