Friendly Fire Mod 1.12.2/1.11.2 will prevent pet mobs from being damaged by their owners. You can also edit the config file to prevent damage to baby mobs as well, however this is off by default. With all of the new weapons added by other mods, and the combat changes in 1.9 it has become extremely easy to accidently kill your pet mobs. In many cases, being careful is not good enough, as they will still be hurt by AOE effects. If you sneak, the mob will not be protected.
