Gabe Newell, the developer Team Fortess 2, has officially signed a contract with PETA Animal Protection Sevices that requires the developers to make a system protect all of animals that are featured in this game.

How do they do it? Well, a professional told me that they will start by removing the hitbox of the said animals so they don't get hurt by projectiles and bullets but instead, they hit the wearer.

Next, they remove the ability for the animal to bleed, get soaked by unknown substances, beaten senselessly with frying pans, being set on fire, or getting stabbed in the back with a balisong/butterfly knife.

Finally, to deal with the people who ACTUALLY want to hurt the animal on purpose for no valid reason, the ability for stuff to show up on the dog such as arrows, blood stains, needles, freaky bread monsters, and such other things, will be removed for every model in the game that represents an animal.
