Our commitment to quality is evident in every set of PoochieBells, proudly handcrafted in the USA and subjected to rigorous testing and inspection. Unlike our many copy imitations our 1.25" bells are made with premium materials, ensuring a clear and distinct sound that can be heard throughout the house. Trust PoochieBells for a safe, reliable, and effective potty/housetraining solution for your furry friend. Crafted with care in America, our custom bells are specially designed for dogs with features like lead-free material, reinforced durability, and smooth texture. Our bells also feature small openings to prevent your pet's nails from getting caught. For added safety, we highly recommend nose-to-bell training. Ensure your pet's safety and convenience with our one-of-a-kind dog training doorbells. Say goodbye to unexpected messes, and complicated doggy door installations with PoochieBells dog bells. Our innovative product is designed to hang conveniently and securely 26 inches from any doorknob, handle, or hook - accommodating any size or breed, from Chihuahuas to Danes. With a one-size-fits-all design, our potty training tool features two sets of bells, requiring no adjustment and making it perfect for dogs of any age, breed, or size.
