We trained Crosley to ring a bell and it works great with her!
We have been doing our best to try and litterbox train Camden, but she's not having it and wants to go out and she's not great about telling us either! I think she comes into the family room and goes back to the door, but we aren't always where she thinks we are and she won't bark or come directly to us!

Last night though for the first time, I heard the bell and figured it was Crosley wanting to go out and I went to the door and it was Camden, it totally shocked us since we haven't even taught her!
