Haven't been able to teach my dog to use these yet but they seem to be good quality and come with a rubber insert on the bottom to keep your dog from sliding on them. around the floor. My only comment: I don't know why one rubber ring was red when the other was black and the bells had black paws. UPDATE: I was able to teach my dog to ring the doorbell when he's in front of the door to go outside. I'm glad I didn't buy bells to hang on my door. I didn't want to listen to them every time someone opened the door.
