We have different gait for the animals when they travel, we have skeletal simulation, it follows that hitting an animal in those parts should affect its mobility. Simply add a "limping" gait that animals move in when injured in the leg bones, they probably would flee normally initially from the adrenaline and shock, but after about 50-100 meters they should start limping, moving slower and leaving confirmation from tracks that they are have been hurt.
