I have gone thru the same thing with my Gizmo, but it was caught in time. I had no idea I was hurting him by feeding him people food. He was so spoiled to it that it took a while for him to accept just dog food. These little dogs dehydrate very quickly, we almost lost him. The hair raises on the back of my neck when people think it is cute that their dog will eat anything they do. The education of this matter almost cost me the apple of my eye.
