Hyenas: Pets of Illagers, which can also do their own little raids in savannas.
Hyenas would spawn as pet dogs for the evil illagers! as 1-3 in raids, and occasionally in woodland mansions in their own block built doggy beds! They would also uncommonly spawn in savannas and rarely attack in their own raids up to 6-8 hyenas, Attacking any savanna animals(and the player!) such as the Ostrich announced from Minecon Earth and any upcoming/unannounced savanna animals. You cannot tame a hyena as your own pet but you can instead bond and trust with it when found by themselves in savannas. when Bonded enough(AKA feed those hungry things a lot of meat.) it will call all it's allies to act upon as your pet wolves for a limited amount of time. and they will no longer attack you during hyena raids. they however, can not leave the savanna, or go underground or else they will lose all trust for you meaning you would have to start all over again. meaning you can't bring them with along your adventures. when you punch a neutral hyena it will become aggressive just like a normal wolf. will also lose trust and it will not drop any items when killed.
