Most monsters that serve as mounts can attempt to buck off unwanted or annoying riders, but most mounts will not use this reaction against a trusted creature unless the mounts are spooked or mistreated.
Trigger A creature Mounts or uses the Command an Animal action while riding the monster.
Effect The triggering creature must succeed at a Reflex saving throw against the listed DC or fall off the creature and land Prone. If the save is a critical failure, the triggering creature also takes 1d6 bludgeoning damage in addition to the normal damage for the fall.

Knockdown
Requirements The monster's last action was a successful Strike that lists Knockdown in its damage entry
Effect The monster attempts to [/act trip] the creature. This attempt neither applies nor counts toward the monster's multiple attack penalty.
Much larger and more foul-tempered than their common cousins, dire wolves haunt primeval lands that accommodate their massive size and proportionately large hunting grounds and appetites. Orcs are fond of using dire wolves as mounts, finding their vicious tempers perfect for hunting and warfare. Dire wolves are far more likely to prey on humanoids than ordinary wolves, considering them nothing but another kind of smaller, nutritious animal.
Wolves roam forests, hills, and other wild lands, where they hunt in packs to beleaguer and surround their prey before going in for the kill. Like most predatory animals, wolves prefer to attack the weakest or most vulnerable prey they can find.
