Great topic!

If I'm expecting someone, the dogs get shut away and given Kongs or chews.

If I'm not expecting it, the doorbell rings, Ollie and Squid run around like maniacs, totally ignore me when I call them and growl and bark loudly enough to scare anyone away. (Normally they're both angels, people coming to the door is the ONLY time they misbehave, maybe cos they think the person is trying to break in or something ) I scoop them up and shut them in the dining room.

Toby sits at the door patiently until I open it, then he offers the person a paw and waits for lots of fuss, which he almost always gets

Then once our visitor's sat down, they're let out to say hello
