I cheated ,
I looked it up. Best I can find is when he starts to fight it's with
his front paws in a boxing fashion.
Could be how he got the flat nose though....

Great breed.

We have in the US a Pit Bull breed, the pedegrees are suck dogs, they
kill children and old people when they get the whim.
Some think it's cool to have such F##### up aggresive
mindless animals , some are sweet but owners rarely have a clue
as to how to raise them , add the natural aggression, it can
be very unnerving, and they can take a punch, I know...
