Abstract: A trailer for a livestock chute with the trailer having a horizontally disposed frame with a forward end, a rearward end, a first side and a second side. The livestock chute is supported upon and secured to the frame means of the trailer. A first selectively retractable wheel assembly is mounted at the first side of the trailer and a second selectively retractable wheel assembly is mounted at the second side of the trailer. A pair of hydraulically operated jacks are secured to the forward end of the trailer and a pair of hydraulically operated jacks are secured to the rearward end of the trailer. The trailer and livestock chute may be raised and lowered by way of the retractable wheel assemblies and jacks.

Abstract: A device for confining an animal such as a dog is disclosed. The device consists of a plurality of sides, an unstable support element attached to each of the plurality of sides and a plurality of couplers for coupling each of the plurality of sides. The couplers allow relative movement of the sides such that pressing against one of the plurality of sides produces movement that discourages contact with the plurality of sides. If a dog contained in the device attempts to escape by scaling a side of the device, the relative movement of the plurality of sides will startle the dog. Consequently, the dog immediately moves away from the side and within minutes typically abandons any attempt to escape.

Abstract: A kennel system for confining domestic dogs consisting of four panel members (FIG. 5A) attached through a spring biasing element (FIG. 8) is presented. Each panel member consists of a first and second vertical corner post attached to upper and lower horizontal members. Each horizontal member contains a behavioral modification element (FIG. 4) for allowing each panel member to balance about a point. Consequently, when the contained animal brushes against the panels, they oscillate. This oscillatory motion startles the animal causing it to move away from the panels and towards the center of the kennel, thus, reinforcing desired behavior. Since the kennel system works in conjunction with the dog's natural instinct to move away from unstable objects, the top of the kennel is eliminated and the panels are lowered to allow for human interaction with the animal while it is confined.
