Personally I would fast my dogs give them home-made distilled water with 1 drop of oregano oil. As far as the commercial raw food I would make certain it is all organic. I'm fortunate the person we purchase our raw food from is a mom & pop business and they take allot of pride in their raw food. Anything commercial I don't trust. Or make your own purchase a meat grinder and go at it. Then you can be sure what is going into the food. American Eagle meat grinder is a good company, they know you are going to be grinding bone and they will not void the warranty, most meat grinder companys will though.
