If you are a clicker trainer, targeting is an integral part of what you do. If you aren't a clicker trainer, you might want to find out how easy it is to teach directed jumps and go-outs - especially when you have a free-standing target that simply can't be knocked down. No more resetting or repositioning soccer cones or target arrows. The Alley Oop works indoors or out, on any surface - grass, concrete, carpet or even dirt. The Alley Oop's metal and hard rubber construction is designed to literally last a lifetime. Stands 14" high. NOTE: INTERNATIONAL SHIPPING IS PROBLEMATIC. The rates have just about doubled in the last year. I would suggest you buy one from J&J Dog Supplies - the only authorized outlet other than my site.
