Abstract: The present invention uses a pack saddle designed to simulate the weight and feel of an actual rider for testing the animal's propensity to buck. While the animal's movement is restricted, the simulated rider pack saddle is placed over the back of the animal and cinched in place with a strap that is remotely releasable. After attaching the apparatus, the animal is released and observed to determine its natural propensity to buck. After a sufficient observation period, the cinch strap is remotely released, allowing the simulated rider pack saddle to fall or be thrown off the animal. The simulated rider pack saddle can also be released as a reward after the animal performs a particularly desired bucking action. In another exemplary embodiment, the simulated rider pack saddle is further equipped with a remotely activated stimulus, such as but not limited to an electric shock device, which can train the animal to perform bucking actions or increase the animal's propensity to buck.
