Efficient Communication: Using a dog bell has been seen as an easier, fun and win-win way for your dog to talk to you instead of barking. Loud enough: The metal bell emits a clear and loud sound from the dog bell, which is easily heard by other rooms even if the dog touches it lightly. Works Perfectly: Just place the dog bell on any flat spot. It's easy for your puppy or kitten to tap with a paw or nose or press the big flat button to make a crisp sound. Portable: The pet training bell can be carried anywhere. Train bells to play games, potty training, pet home training. With patient training, most pets are able to learn to touch the dog training bell in about a week and fully learn to tap them to go outside or eat or toilet train the next week. Package Included: 5 x Pet Training Bell
