I know for a fact that Vet's get kick-backs for referring Science Diet.

This was told to me directly from a Science Diet Rep. a couple of years ago.
Personally, I feed all my doggies Eukanuba still. I like reading these posts because I wouldn't mind changing to a "better" quality dog food. BUT I have never had any problems with the Eukanuba, Small Breed Puppy and my doggies are all healthy, and have nice coats!
Maybe we should start a survey about the dog food everyone feeds their Yorkie to see what the majority likes...it would be interesting and great information...
