Sometimes there is a fine line between correction and over-correction. It’s often hard for a novice to know when they are correctly on the “line”, when they have gone over the line or sometimes … which side of the line they are on.
Unfortunately in some dogs this line is razor-thin between getting your point across and shutting your dog down and making him harder to correct in the future. You need to make sure that the dog understands your correction but not at the expense of pushing him over “his” line.
So, how do you make sure your corrections are “correct”? Take your clues from your dog … what are his ears doing, his eyes, his body. Do his eyes have panic look in them? Then you are putting too much pressure on or he’s just not understanding what you are asking of him. Is his body trying to lean away from you because he’s trying to go wider? Or is he just trying to avoid you because he doesn’t want to acknowledge your input. Is he leaning toward the sheep and the only “thing on his mind” is when does he get to move again (implying he’s really not all that interested in what you have to say). If so then he’s not taking your correction seriously.
Your correction needs to get into his MIND and what he’s THINKING not just his body. You may have gotten him to lie down BUT if all he’s thinking about is getting back up … he didn’t get a correction … you just stopped the action. A lot of people train by making the body correct but never get into the dogs mind. This either transfers into a dog that won’t move without being told or one that spends all his energy fighting the handler – never working with them. He needs to acknowledge you and try to understand what he did wrong and what you want from him.
Some times a hard dog will respond better to a soft correction … the harder you push … the harder it makes him. However, “sometimes” hard dogs need someone to convince them they can’t always have it their way or they won’t get to work. It takes experience to know the difference. Of course, the only way to get experience is by doing it … which is a bit of a dichotomy for novices :@).
Learn to read your dog to see if your corrections are “hitting home”. Then to complicate things you need to keep the sheep “in the back of your mind” during a correction. If the sheep are running off it’s going to be hard for a dog to pay total attention to your correction. Like everything else is life … timing is critical :@)
