So the trainer for this police dog has protection for his arm. Underestimated how smart this german shepherd is. Its avoided the padded arm and gone straight for the crotch. I doubt he had protection there. Clever dog. He knows a man's weakness. No wonder the guy looks angry.
Wellm the dogs arent quite riding the bike, but they are passengers on it - all 3 of them. 2 in baskets and one resting on the back of the man rider. That is some balance from the resting dog. Cool.
