I heard long ago that omega-3's helped prevent all types of diseases and led to longer healthier lives. It can be tricky getting a pet to take a supplement but these are easily tossed into my big dog's mouth. The cat I tried feeding one to just played with it and it was a little gross but I think most ended up in her mouth.
Our dog is very small so I am thinking a smaller dosage at a lower cost would work. Product is fine, but expensive.
