I'm having trouble switching over from people food to dog food. My 2 year old " Chorkie " can hold old longer than I can. He has never eaten dog food and so I constantly worry that he gets the nutrition he needs. Everyone tells me " give him a bowl of dog food and don't give him anything else and he will eventually get hungry enough ,and eat it. I've tried mixing a little bit with his food to get him use to the taste but he's smart and won't eat any of it. Does anyone have any clues how I can get it done?
