Grayson is seven months old and over 60 pounds. I was feeding him at set times--to help with the house breaking thing. And I didn't want him to overeat and make himself sick. Lately, he'll take a few bites and walk away. Come back a little later. For the most part he is housebroken--an accident here and there. And I don't mind letting food sit out--since my yorkie is a grazer anyways it would be easier. But I am also worried he has cut down how much he is eating. I was using the directions on back as a loose guide for amounts and he was eating it all up, now though he is letting food sit.
