I think it's sad that ppl who breed those dogs, for a long time, since 1850 - has destroyed their natural look. Just saw a program for some days ago, they breed the Mom and Son ( doggy son and Doggy mom ) to create , a better looking dog. Not all breeders do this ofc. Those Bull Terrier's looked totally different back in the days, but anyhow, cute dog. They breed in families for making the genes stronger, which makes them weaker against some illnesses..
NO OFFENSE TO UR DOG!
