An apparatus for demonstrating animal agility. In one embodiment, the weave apparatus includes a rail with a set of releasably removable legs. The apparatus has a plurality of joints that each secure a leg to the rail. The joint includes an axle that the leg pivots about relative to the rail. The joint in various embodiments includes a toolless releasable latching mechanism and/or a locking mechanism. In an embodiment used for training, the legs are grooved or slotted for engaging by a slider. Each slider engages one of the legs and includes a vertical projection that engages a pole. With the slider fully engaging the leg, the projection and pole are directly above the rail centerline. In a competition style embodiment, the legs provide support for the rail and the peg for the weave poles is attached to the rail.
