This freestanding target replaces the old Alley-Oop which was very popular! This target is useful in teaching many agility skills, including contacts. After the foam ball on top is touched by the dog’s nose, the weighted base rocks back and forth. The telescoping rod on this Freestanding Target telescopes from 7" to 23" high. You can remove the rod from the base to use it as a hand held target stick or for easier storage.
