All dogs vary due to breed. "Pit bull" isn't a breed, it's a catch all term. Since you described your dog as a blue nose, I would suspect it's an American bully, which tend to go a little heavier. Since there isn't much in the way of standards with AmBullies, the best way to get a fair guestimate is to look at the dam and sire. As long as your pup is healthy and the vet says he isn't too fat and isn't too thin, you shouldn't get too hung up on the numbers.
