Very good

We have been feeding Diamond Maintenance for approximately 13 years. We have never had a problem with over weight or under weight dogs. We have 1 Great Dane, a Great Dane mix, and 3 Yorkies. We feed it to all of them and they love it.

Can't afford it anymore!

We fed this for several years until they priced themselves out of our price range, with three big dogs price matters!

Works Great

It's one of the few dog foods that we have found that my picky 8 year old mutt AND 3 year working line German Shepard will eat and not have allergy affects. My mutt would get skin rashes and/or not eat and my German Shepard would get ear infections and chew at her feet on most of the other dog foods we tried.
