Gizmo, my little boston, is abnormally large for his size as well. his mother and all his siblings turned out to be around 15 to 16 lbs, whereas Gizmo grew to be a whopping 25 lbs!! (and he was the runt of the litter!) Hes definitely NOT fat in anyway, and the vet says hes very healthy. Were thinking its his activity level that made him larger. maybe your lil guy is just a larger boston like Gizmo. as for the look, ive seen many different looking bostons. i wouldt doubt hes a full boston. (hes very cute by the way!)
