Our dogs loved this food! We got a gift basket that included Ideal Balance Grain Free dry and canned dog food and dog treats and our dogs loved them! The box was delivered and our 13 year old Chinook tried to chew through the box to get to the goodies inside. When we tried the canned food we were pleased with the consistency, and the dogs really seemed to like the flavor. We tried the treats solo and then offered them with other treats and they selected the Ideal Balance treats first -- that seems like a good testimony to me. December 18, 2013
