Wolves in vanilla are kind of useless. They attack stuff, sure, but then they just stand there while the loot despawns. This mod fixes that.
Smart Hunting - Wolves stop attacking once the target is dead. No more watching your wolf lunge at a corpse.
Meat Collection - After a kill, your wolf grabs the meat and brings it back to you.
Hostile Detection - Your wolf growls when hostile mobs are nearby. Works as an early warning system in caves or at night.
Item Fetching - Crouch and your wolf will fetch nearby item drops and bring them to you. Useful for cleaning up after a fight.
Everything can be toggled or adjusted in the config file:
