I don't have a doorbell but the Bagel doesn't bark. He leads me to the door (Kinda of a follow me dance) and jumps around to show me that the door needs to be opened. Most of my friends call first and 1 tell em to just come in so the Bagel is my official greeter, he meets them at the door and shows em which room I'm in after collecting his greeter fee (A pet and some kind words).
