Ethical Pet Gotta Go Training Bell
When puppies need to go out, give them a better way to let you know with this Gotta Go Bell from Ethical Pet.
Hang the bell over the door knob and it will ring when the door is opened or closed. Your puppy will start to associate the bell sound with access to the outside. Once they make the connection, start encouraging them to bump the bells with their nose to make the sound. Before long, your puppy will be ringing the bell to let you know they need to go out!
