My sister has a pittie or amstaff type pup. He's a goofball and doesn't know his own strangth yet, but not the least bit scary. He's 7 or 8 months now and neutered and raised as an indoor pet with lots of socialization so he's being raised the right way. I do however cross the street or avoid coming into contact with ALL UNKNOWN DOGS of any breed unless I speak to the owner and ask if their dog is ok meeting another before we get close enough for them to have contact. Autumn has gotten attacked by a beagle before. Any dog you don't know, of any breed, can potentially attack your dogs.
