Hi Just wanted to ask about the different builds of the staffordshire looking at a few different litters/pups and their parents i noticed some of the parents were quiet "tight"( like they have had a face lift) their front legs appeared thin and long, and some others were very thick set, wide, with lots of loose skin, all had excellent personalities and temperments ect, just wanted to know from a breeders point of view the different builds and exagerations Thankyou
