Deer and Grizzly Bears! (for the dappled forest)

Deer could be found wandering around the biome and would run from Grizzly Bears and players (maybe they wouldn't run from you if you're shifting). After a really long time or maybe with a low chance when killing them, they would drop their antlers with could be used to throw them and make any dog you have around and own go to them, maybe being useful to either just play with your dogs or to make them go a specific way and attack any hostile mob that's close and then one would pick it up and return it to you along with all your dogs. They could maybe drop their meat too.

Grizzly Bears would hunt deer if close to one and would hunt players only if you suprise them by running close to them or to protect their cubs, but you can make them ignore you by staying still and shifting until they leave. Maybe they could drop their meet too or their for for something but I don't have any ideas for it.
