That's Bishop. I just got him today. At 8 mo. old, he's already 55 lbs. The SPCA called him a pit mix. I saw it at the time, but now that I got him home, I'm seeing the molosser (Great Dane body type-ish, Rotty colorings?) but not as much of the terrier (but he does sort of have those funny/confused pit ears I see sometimes). He's incredibly strong and playful, a bit crazy.
What do you think?
