PETA won't like the concept of killing a dog. Unless, Valve modified the class.
PETA always takes everything with animals a bit too far, for example, they copied 2 Nintendo games without asking and made it about people who murder animals, and they also protested on WoW how you're able to kill Seals. They go way too far.
That's because they're stupid and don't realize the killing of animals is something human are meant to do, for survival.
Idea:Dog slows down for 30 seconds after running for 1 minute.
Or, don't add this piece of stuff into a perfectly fine game. I'm all for adding weapons and stuff, just no new classes.
Keeping animals out of tf2 keeps the furries away.
It'd be much better as an Engineer unlockable (see: mounted turrets).
Fallout 3 has dead dog bodies everywhere. Wat?
