[WIP] 3 additional dog zombie specials

Skeletal dog: Identical to human version of skeletons. It's frail, but fast and resistant to ranged attacks.
Z-9: Dogs in law enforcement. *Should* drop a kevlar harness (and a leather collar) on death, which right now, can only be cut into plates to be used in crafting. 
Rotweiler: I was thinking of making this ones attacks to very likely to cause infected wounds, but its beyond my ability. So, I just made its attacks poisonous with "VENOM" flag.

Right now, I could use some help with monster names and their descriptions.
