American bully. Shorter stature breed that kinda looks like a pitbull but isn't. Also it isn't an aggressive breed generally speaking like a Pit bull
"Pit Bull" doesn't really mean anything. "American Bull Terrier" is one of the 3 or so dozen breeds that fall under the "Pit Bull" umbrella, and is actually the one specifically bread for ripping off faces and tearing out throats. ....but dog faces and throats. They were rather aggressively bred
against violence directed at humans...but ah, are still indicated in the majority of "pit bull" attacks on humans; almost entirely because it is the most popular breed out there, so there are tens of thousands of them.
TL/DR: that one that you have there is, indeed, a throat-chomper.
