I saw some growth charts out there, and while I know they are not absolutes I am a little concerned about his weight. He was at 10lb when we got him at 9wk and has gained about 2-2.5lb a week which ive been told is the norm. Breeder fed him royal canin for small breeds because she said he liked the kibble size. I tried eukanuba large breed but he did not like it, so now have recently transitioned to Blue buffalo puppy kibble which he seems to like. He typically eats a bit less than the bag recommends but isnt skinny at all. Im wondering if hes just gonna be a small dog, or if he'll have a growth spurt. Opinions appreciated.
