If you befriend them and become a Hangdog warrior, you can spend some time training with the Hangdogs and learn their unarmed style, "The Way of the Dog," which might involve a lot of tripping/knockdown.
The Hangdogs have their own fighting style involving lunges and trip attacks.
I trained with Teacher to learn the Hangdog fighting style.
Hangdogs fight special like dogs.
Hangdogs teach me how they fight. I fight like dog now.
Teacher will also teach you the style if you let him borrow Devil Dog to breed one of the pack bitches.
