But I'm hungry .... again

Dad was explaining to our boy why he wasn't going to get more food until it was his dinner time. Our boy has a habit of looking at you as if you haven't fed him for days .. when he fact you just have. I can see how dogs can easily be overfed .. when they look at you with such big cute eyes . The vet warned us that he was starting to look a bit "pudding" like so its been a bit of Boot camp and tough love I'm afraid
