We adopted a dog from a rescue shelter last August and named him Neus (“snow” in Catalan). He was described as a Pit Bull / Terrier mix. While he may have looked like one at the time (esp. a Boston Terrier), he’s grown to almost 60 lbs. We think he has some Border Collie (always chasing things and organizing balls) and possibly Great Dane in him, but aren’t sure. What do you think he is based on these photos? We’ve heard everything from Domo Argentino to American Staffordshire.
