My daughter uses this type of bell for potty training her beagle! She hangs it on the door and the puppy "rings" the bell when he needs to go out! During a recent move, she lost hers. We searched everywhere for one. Even though it was a few days after Christmas. all of the stores had Valentine merchandise out already and no Christmas clearance. Thanks to Anytime Costumes, we found one! It jingles loud and clear and the cord is the right length to hang low enough from the doorknob for the puppy to reach with his nose. Thank you so much for providing a quality jingle bell necklace that has many uses!
