Review on PoochieBells Classic Collection: The Original Dog Potty Training Doorbell - Made in USA! by Stacey Littlejohn

When my Havana puppy was 7 months old it was Christmas time and we had little Christmas decorations hanging on doorknobs with jingle bells. My dog quickly noticed that they make a noise when the door is opened. The first day she came and rang the bell and every time she did we opened the door to let her out. She trained us in about two days. She rang once then sat and looked at us until we came over and let her out. After Christmas we bought a set of these bells so she can keep telling us to go out and because they ring louder than Christmas ornaments. We have since moved and need an extra set of bells to hang on the other door that she is allowed to leave. The cutest times are when she needs to go to the potty urgently or when she's spying on her puppy friends. for a walk, etc., she'll be ringing those bells so insistently. And sometimes when she's just bored and wants to go outside, or when she sees we're about to leave but we're moving slowly for her liking, she rings the bells once and then waits a few minutes to see we're coming not earlier. Ring the bells again. My pup will be three this year and there is no wear or damage to the strap on the bells. They are really solidly made.
