He will not starve himself, try only feeding him from his bowl...no handouts. If you allow this as a puppy, it can lead to a serious problem later if you have to leave him at the vets overnight or else where when boarded. And can possibly lead to an anxiety issue when he is older.
Put his food down, wait until he starts to eat then leave the room. If he leaves it take him back to it or pick it up and feed him later.
We feed all the girls within a 3 foot area of each other. They know that if they leave their food it gets eaten by someone else. They are not allowed to butt into someone else's dish, however if they leave their bowls uneaten they runnthe risk of someone else eatting it. Maggie and Hannah hardly taste their food I swear that I could serve them sawdust. Zoe' is a slow methotical eater, Maggie will sit patiently waiting for her to finish each meal.
When Buddy is here he eats in the hall bathroom, as soon as I touch his dish to pick it up he heads from the rug to the bathroom and sits and waits (where he will sit until his dish comes). I do this to keep Zoe' from attacking him when he walks past her, go figure she is 17 lbs, Buddy is 72 lbs and she picks on him horribly. She does this cause he will not fight back.
