Louie is 6 months old and is 43 pounds. He's not fat by any means. He's very muscular and you can see his ribs slightly. My big question to everyone is, when do they usually stop growing? I've seen a lot of you have around 45-60 pound dogs and they are mostly over 2 years of age. Louie is around that weight already. So will he no longer grow and just fill out as the years go by? or is he going to be one of those huge dogs? We don't know what his parents looked like, and I know that that has a lot to do with it, but on average when did your dogs plateau with their weights? Just so we can figure out if we need to buy larger sweaters for him for the future..lol
