The Ricochet Electronic Dog Toy is an easy way for pet owners to ensure their dog stays mentally stimulated and physically active. Includes two toys that alternate squeaking sounds to keep dogs intrigued. When a dog investigates one of the toys, the other will make an exciting squeak sound. When the dog interacts with second toy, the sound will bounce back to the first toy. Durable enough for intense play, it has a pairing range of up to 30 feet. It is easy to use and set up with an automatic pairing system. After 60 minutes of no activity, the toy turns off to conserve battery life. The toy has a battery life of up to one month with daily use.
