Yes! The toy rabbit idea is apt, because most dogs will develop a very strong appetite the moment there's any competition for their food. So, Susan, you have to get someone else to play the role of attempting to "steal" the dog's food! A cat, another dog, your husband, your cousin, whoever...must appear to be interested in eating the dog's food. Dog will suddenly become ravenous. Problem solved. :-)

Either that or improve the quality of the dog's rations, cos like I said, that dog is not stupid.
