2x Attack (DC 20):animal attacks apparent enemies. You may point to a particular creature that you wish the animal to attack, and it will comply if able. Normally, an animal will attack only humanoids, monstrous humanoids, giants, or other animals. Teaching an animal to attack all creatures (including such unnatural creatures as undead and aberrations) counts as two tricks.
Come (DC 15): The animal comes to you, even if it normally would not do so.
Defend (DC 20): The animal defends you (or is ready to defend you if no threat is present), even without any command being given. Alternatively, you can command the animal to defend a specific other character.
Down (DC 15): The animal breaks off from combat or otherwise backs down. An animal that doesn’t know this trick continues to fight until it must flee (due to injury, a fear effect, or the like) or its opponent is defeated.
Exclusive (DC 20): The animal takes directions only from the handler who taught it this trick. If an animal has both the exclusive and serve tricks, it takes directions only from the handler that taught it the exclusive trick and those creatures indicated by the trainer's serve command. An animal with the exclusive trick does not take trick commands from others even if it is friendly or helpful toward them (such as through the result of a charm animal spell), though this does not prevent it from being controlled by other enchantment spells (such as dominate animal), and the animal still otherwise acts as a friendly or helpful creature when applicable.
Flank (DC 20): You can instruct an animal to attack a foe you point to and always attempt to be adjacent to (and threatening) that foe. If you or an ally is also threatening the foe, the animal attempts to flank the foe, if possible. It always takes attacks of opportunity. The animal must know the attack trick before it can learn this trick.
Maneuver(Bull Rush) (DC 20): The animal is trained to use a specific combat maneuver on command. An animal must know the attack trick before it can be taught the maneuver trick, and it only performs maneuvers against targets it would normally attack. This trick can be taught to an animal multiple times. Each time it is taught, the animal can be commanded to use a different combat maneuver.
Work (DC 15): The animal pulls or pushes a medium or heavy load.
