Max isn't a police dog, so he wouldn't have grapple training, but this attack can count as a bite as you described.
Erica didn't meet the AF personnel the first time she was at the T-Bone. She rode in on the truck and didn't interact with them, though she did see Lereux, Duran, and Zorie Spooner when they stopped the truck. She would probably have some knowledge of their rules from her own time in the service, so she can make a Know roll.
I edited Duke's character sheet to reflect that he has 50% Club skill. Since he's carrying a rifle, he would use Rifle skill if he were to parry with it, but that's also 50%. Only one rat is attacking him, so that's the one he would parry. He cannot both fire the rifle and parry with it in the same round. If he swings the rifle as a club, I'm not sure if he'd still get a parry with it since it isn't really a balanced weapon like a sword. If he attempts a kick, he may parry with the rifle. Keep in mind that in the event he does parry a successful attack, the rifle will take the damage. However, that's a lot better than Duke taking it, and the M-14 would probably have 11 HP so it almost certainly won't break from one attack.
Zombie cats would of course have to be killed nine times before they finally stayed dead.
