A rattled keychain works pretty well, if the dogs have been briefed.
We had a Magnavox TV with an ultrasonic remote that drove our dog bonkers..
When I was a bored kid late at night, I used to sneak up on neighbors'
dogs. When I'd get close, I'd suddenly rattle my keys and surprise the
dogs. After a while, all I had to do was open the door and shake the
keys, and the howling and barking ensued.
