In the traditional style of HnH, bears can be aggroed on an alt and used to smash things (in this case animals). Wander around the bear until it aggros, then run in the direction of what you want to kill. When the target is in sight, dodge the bears attacks to get them to aggro the other animal (or let it ko you and wait). This also creates dead bears for harvesting.
Due to homestead teleport, this is very easy to accomplish. I'm completely unsure of how to rework the system to prevent this, but it makes "hunting" easily possible due to animal concentration around jorb stains (gametrails) in forests.
