I'm laughing.
Maybe an American Bully Terrier, or a Pit Bull mix with something like a Bullmastiff, but not a pure bred American Pit Bull Terrier.
Somewhere, an English Staffordshire Terrier will get a bad rap for this, even though the males average in the low 30 pounds, and they never hit 40 pounds.
Ah, the Staffie: "because of their natural fondness for people, most Staffords are temperamentally ill-suited for guard or attack-dog training."
Yet we have American Pit Bull owners calling their dogs Staffordshire Terriers to get around Pit Bull bans, giving the Staffie a bad name.
I cannot count the number of yard sales that I have blithely swaggered into, only to be slobbered all over by the resident “guard pit” or Rott.
Oddly enough, I would ~not~ sashay into a Dobe or Lab’s yard.
