Saw this clip while viewing anti-BSL videos. I'm not sure what kind of dog that is -- anyone know? It's ENORMOUS. Looks like he still has some work to do(?).. I don't know, I'm surely not an expert. It kinda got scary toward the end, I wasn't sure if he was gonna go for something other than that "arm" or not!
