How many pounds does your 11 month pup weigh?
My guy's 11 months and probably around 60-65 pounds and 24" at the withers. Skinny, lanky, and has a lot of filling out to do. I'd guess he'll probably top out about 75 when he's fully mature.
Weight isn't really something I'm ever concerned with. He's healthy, active, fit, and has a great appetite. That's all you can really ask for.
