What is a command you accidentally taught your pet?
My goldendoodle puppy doesn't ever want to come back inside. I told my beagle "go get your sister" as I tried rounding up the puppy. Now when I say "go get your sister" the beagle runs to the puppy and baits her into chasing him into the house.
The beep one of my monitors makes at power off (at the end of my workday) catalyzes my three cats into immediate action. They could be passed out or hidden, and ignore me when I walk by (I've tested this), but the moment they hear that "beep-chime" they materialize.
They know it means I'm available for cuddles and snacks. Confuses the hell out of them on the occasional weekend when I take a Zoom call for one of my volunteer gigs. I'll also use it to summon them when one vanishes for too long and I need to make sure they didn't get out.
