Thats where your going wrong, the dog is manipulating you, do not let it happen, put his food down, and after 10 minutes if hes not touched it, take it away, a dog will NEVER starve itself to death if it can help it as they are scavengers, he knows whats coming hence why hes making a pass at his food waiting for the good stuff.I' so I've done what she said and leave it down and it goes untouched
