“I drove my Border Collies crazy for a few weeks trying to teach them to wait at the door as a group and then go outside one at a time. Each dog could go out the door after I said his or her name, followed by the word OK. As soon as I said “OK,” not surprisingly, all the dogs would get up and move forward, no matter whose name preceded it. I knew it would be hard for them, since they had all learned as individuals that “OK” meant “Go ahead and do what you want.” But I thought that if I were clear and patient, they would learn to move only if they heard “OK” after their own name. After a couple of weeks, I was frustrated and my dogs were confused. Pip was so distressed that she started to stress-whine. Pip gets the connection between a sound and an action faster than any dog I’ve ever had, but she never could figure out that “OK” only related to her if her name preceded it. She’d sit waiting at the door, I’d say “Luke, OK,” and she’d start to move forward and backward, clearly unsure of how to proceed, searching my face for clues until she began to look stressed when I moved toward the door. She practically wrapped her paws over her ears.”

“If “OK” meant that “it’s all right to get up now,” it makes sense that Pip would respond when she heard it. So if your dog Chief can pick the word sit out of the middle of a sentence, what is he to make of “Good sit” after he already sat? With Pip I got caught up in using words as if I were talking to a human, and I think other owners replicate that mistake often.1”
