If you are a clicker trainer, targeting is an essential part of your training. If you haven't tried clicker training, you might be surprised at how easy it is to tech go-outs and directed jumping using targeting. This patented, freestanding target works on any surface-indoors or out-and cannot be knocked down. After the dog's nose touches the foam ball at the top of the ALLEY-OOP, the rounded, weighted base of the unit quickly rocks the target back to vertical. Stands 14"H, with durable metal construction for lasting service.
