No more accidents in the house. Train your dog to use the Poochie Bells to let you know when he/she needs to go outside to the bathroom. The Classic Solids Poochie Bells Collection features solid color grosgrain ribbon with durable rings and bells. • Every Poochie-Bell comes complete with EASY training instructions as well as a super shiny dog bone charm. Based on our on-line survey, bell training is 95% successful when implementing our suggested training method. • Poochie-Bells are the perfect combination of function and design. • Handmade in the U.S.A. using durable ribbons and quality materials. • Two sets of strategically-placed bells that are carefully folded and snapped securely into place. This design allows for all breeds (sizes) to reach the bells. • Our bells are custom made especially for us and are crafted from heavy duty metal with a polished finish (not ordinary craft bells); so, they won't be destroyed, ensuring your dog's safety. Four bells on each Poochie-Bells unit allows you to easily hear them ring, but not so loud that they are overbearing. •Top snap opens to fit and adjust for any door handle type. • Great for travel, no messy installation, designed to hang over any doorknob. • Endorsed and preferred by professional trainers and breeders. • For dogs 10 weeks to 16 years+, all dogs can learn this behavior, bell train your dog in days!
