Using a pool noodle over a pigtail is an excellent training aide for teaching turns and go on cues.
Teaching your dog to go around the pool noodle
Swapping food for tug toys and gradually increasing distance to the pool noodle
Adding a jump next to the pool noodle
Use two pool noodles to work on making your direction cues fluid. Stand in between two pool noodles (2-3 meters apart) and your dog by your side. If your dog is on your LEFT SIDE, step towards the Right pool noodle using your Left arm to indicate the dog should go around the pool noodle in a clockwise movement.
When your dog is on your RIGHT SIDE, step towards the Left pool noodle using your Right arm to indicate the dog should go around the pool noodle in an anti-clockwise movement.
