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.
It's not as exciting as an 80's movie. She just was staring at me one day after she just came in from a walk, had food and water available so I just started saying random words until I got a reaction. It's the only phrase that has no meaning to her to makes her speak out at all.
The only other phrase that makes her speak (and run away) is "bath time."
