they are the same dog look up the breed. most real breeders crop the ears and chop the tail lol same dog. our "staffords" were 80 to 120 lbs lol thats the only way to get akc papers on a pit if you look at both breeds they act the same were bred for the same thing in a correct bodytype of either breed only diff would be size lol some breeders get pissed off but thats what some people do. frnkly i think all dogs by this time are muts anyway lol so to me the name "pure bred" is pretty loose term
