With the exception of aurochsen and mouflons, all animals has a damage threshold in which they will flee. The condition for fleeing is different for range and for melee as well.
For range, each shot that deals 10%+ of its HP will constantly increase the chance of it running.
For melee, they will are much less likely to flee until they are low on health, then the chance of them fleeing is how much damage over 10% you have inflicted before it.

An enemy will only fight if he believes he either has a chance to win, or you've backed him into a corner and he's fighting for his life. A completely crushing victory provides an enemy with neither.
