We are enjoying Xena and just wanted to send some recent photos. She certainly is a busy puppy! She seems to be all legs now. She rings the bells on the door handle to get outside. If I'm not fast enough she practically pulls them off the door. Can't get enough of the ball/fetch game either. She is impossible to tire! Take care, laurel
And, as you see: yes, you can train a Papillon to ring a doorbell, needing to go outside.
You install a small bell, hang on a rope/ribbon of the door handle.
