We designed this leather and brass dog doorbell in response to numerous customer requests for premium materials. If you're seeking a more elegant alternative to polyester and iron doorbells with a clearer, crisper ring, this is the perfect choice. It's not just a practical tool for potty training—it's also a beautiful decorative piece! The best way to potty train puppies is to teach them to ring a bell when they need to go outside, rather than barking or scratching. Simply follow our training process to help your furry friend master this skill quickly. Potty training shouldn't be a source of stress for you or your puppy, but we understand the process can be challenging—our goal is to make training easy and enjoyable! Let the CATHYLIFE Dog Bell give you a helping hand!
