First time poster with two BC Questions in General Border Collie Discussion Posted November 11, 2017 · Report reply What I'm going to say seems to be the minority view on these Boards, but I'd say it's the majority view among working dog people. IMO, a dog should know what a correction is. I use "Ahhp" and it's important to me that the dog learn that if she hears it, it means that what she is doing, or is about to do, is wrong. You don't have to bellow it or use an intimidating tone -- once the pup learns that it's a correction, you can use it in a soft, reminding tone. The length of time it takes for a pup to learn that it's a universal "No" can vary a lot, but you'll know it's happened when she discontinues doing what she was doing or was thinking about doing. Very seldom do I care what she does instead. When she's little, I would likely give her a chew toy at that point to show her that there are other okay things to do that are fun, or take her outside to show her that's where she's supposed to go. But that's early in training, when she's pretty clueless in general. I would hope not to have a grown up dog that had to be shown "what I want her to do," when there isn't anything I want her to do except stop doing what she's doing. My ultimate aim is for her to know that she has to stop what she's doing, and then decide for herself what she wants to do instead. A working sheepdog needs to think for herself in many situations, and by approaching training this way I feel you're more likely to develop a thinking dog. I think it does matter somewhat what word/sound you use as a correction/interruptor. I like "ahhp" because it is not used in ordinary conversation, and because it is a sharper sound (no matter how you say it) than "no." Just by its sound, to the dog it comes across more like a warning than "no." And the person who says it is less likely to feel oppositional when they say it than when they say "no." Which matters, because you are not your dog's opponent in training, you are her partner. This may seem fanciful, but I do think these subtle characteristics of sound and usage make a difference. For those reasons, I think "stop" would come across better than "no" for what you would want to convey. But not as well as "ahhp."
