I've heard "double the weight at 4 months" and I've heard "double the weight at 6 months" and all kinds of other "formulas". In anyone's actual experience, is there any truth to it, or is it all just a matter of being patient and waiting to see what your pup turns into? I've heard that pups whelped by humans (bottle fed) don't get as big, and I've heard that pups altered before a certain age (especially the boys) don't get as big. Just wondered what was true and what was just jibber jabber.....Koj i (berner/aussie mix) is 14 weeks today and weighs about 18 pounds. His feet are gigantic and his tail is like 10 feet long, but his legs are still a bit stumpy. He was a bottle baby, and he's not neutered yet.
