We have short legged 4 month old Bitch.  She is black and tan with some white markings.  She is often mistaken for a Doberman or Rotweiller puppy by people who dont know the breed.  Is she unusual?

what breed is she?

if she is a stafford then its not unusual just a colour that is not bred for as its not in the standard.  my friend has a balck and Tan and ppl often think that she is a small Rottie
