The Memory Trainer Activity for Dogs requires patience and concentration as your dog learns the association between the remote release button and the food dispenser. Treats are released when your dog presses the remote release button, which has an operating range of up to 43 yards. Regulate the release of treats using the rotating reservoir with adjustable opening located inside the food dispenser. Increase the level of difficulty by varying the placement and distance between the release button and the dispenser. We've also included a peg and suction cup for securing the release button to the ground or for wall mounting. Includes a booklet with tips and tricks to design a training program. Suitable for dogs of all sizes and activity levels. One year warranty. Color: lime green/white. Dimensions: 7.75 x 7.75 x 9.25 Inch. Materials: rubber, plastic.
