I reviewed this for cats also, because we give it to our dogs and to our cats. We purchased from our vet to give to our cat and then purchased more for our dogs. We have a little one with heart disease and I LOVE that this has the right amount of co-Q10 in it! It also has ingredients which make their bodies inhospitable to cancer. We have a foster dog with cancer and we started him on it. I wil update in a few months. Reputable companies are important to me and after a bad experience with a company who I thought was the real deal, I checked these folks out THOROUGHLY. They will actually talk to you and they do a ton of good things for seniors in rescue.

Pros: Easy to give. Dogs love it

Cons: hard to find

These people and this product were a godsend. Our beloved Judah was diagnosed with aggressive bone cancer in May 2010, and we were told to say our goodbyes then and there. We opted to take him home and to manage his pain for the weekend. I knew of Katie from a woman at the rescue where I volunteer. I sent her an email and she had just started making Immune Support. Fate, perhaps?

Fast forward to January 2, 2011. Our beautiful boy passed peacefully in his sleep. No struggle, just passed. Thanks to EnduraPet, we had not only our last weekend, but a last spring, summer, fall, many holidays, and most importantly to Judah, more camping trips!

I still use this for our little dog and our senior cat.

Pros: our dog loved the taste,

Cons: none
