Pet Friendly Fire

INTRO: I enjoy taking my pets with me whenever I go places in my world, but something I always worry about is that I might accidentally hit them while trying to fight monsters or break blocks.

IDEA: So I just randomly thought, what if there was an option to turn on friendly fire for pets such as tamed wolves, cats, parrots, horses, etc. I think it would greatly improve the experience for people who love having MC pets and remove the stress of accidentally punching or possibly killing them if holding a weapon.

FUNCTIONALITY: The way it could work could be to have an additional setting under player friendly fire and when turned off, prevents any players (including players other than the host) from punching tamed mobs in the world.
