House training is music to your ears with the Mighty Paw Metal Brass Tinkle Bell Dog Doorbell. Allowing your dog to communicate when it’s time to go outside, just hang this bell by the door, and your paw-tner can be easily trained to swat it when nature calls. An attractive alternative to hanging bells, the discreet and charming design is easily mounted, and can be hung at any level to accommodate pups of all heights. And most importantly, it’s crafted from durable all-metal brass, with a pleasantly clear sound that can be heard from other rooms.
