Happens to me all the time. I have a 92 lb american bull. I get the "that is the biggest pit I have ever seen" thing a lot. Even more so since he is brindle and white. My guy is compact so he is not very tall. I would say about 25 inches at the shoulder. But very muscular and has the big square head. Since he is a hybrid type he has a medium length muzzle instead of the short muzzle you see on Johnson type bulls (which his father is)
That is to funny. I have a buddy who used to have a 120lb mastif.. Everyone always said that is the biggest pit I have ever seen. We used to roll our eyes and just walk off. I am sure people thought we were dicks, but I just can't stand idiots who make themselves even more retarded then they are.. He hated it.. Now if someone asked what it was, he would stop and educate them all day.
