I'm a new York owner. We got Banjo 4 weeks ago, and he was 7 weeks, he weighed 2.5lbs then, and now he is nearly 12 weeks and weighs a whopping 6lb already.

He is very long and tall. He does not eat much breakfast, around 3tbls kibbles. then lunch is 3tbls kibbles and 1 tbls wet mixed, same for supper. He would eat more, and always seems hungry. Mooching around the kitchen floor for scraps. He gets 1 or 2 cheerios for treats or bits of raw carrot. His mother was around 9lb and his father only 6lb. My boy I think is going to be a monster. He gets lots of exercise, we have a huge yard and take him on walks every morning. How much bigger is he going to get? should I get him tested for hyperglycemic or anything else. Should I be feeding him more or less. Input would be appreciated also some pics of what a 12 week puppy looks like. I have a suspicion that the breeder did not give me his correct age, as out of a litter of 7 there was only 3 males left when I got Banjo.
