Some things just make sense, whether you hunt with dogs or not. This is one of them.
If your goal is to have a steady dog that holds his point even while a bird rattles into the sky, this might help.
Dogs seem to be curious creatures. Unlike cats, curiosity probably won’t kill the dog, but it could cause him to break on a flushing bird if he feels like he’s being squeezed out of the action. On top of the others I’ve mentioned, here’s another good reason to be strategic about approaching a pointed bird: obscuring his view of the action could encourage him to move so he can watch the proceedings … even when you want him to stand sill.
This was driven home to me in a training situation just yesterday. I’d set up the bird in a launcher so it was hidden by tall sage. I brought Manny in crosswind, and he stopped at the first whiff of pigeon, front leg lifted in anticipation of the joy to come. Unfortunately, he was pointing scent that had wafted through yet another tall sage, so when the bird lifted he couldn’t see it. At the flush, he jumped left as if on springs, back on point when he landed. From his new vantage point, he could see the arc of the flying bird.
There was no intent to break point, or chase the bird. He simply needed a vector on it so when time came to retrieve he’d know where to go.
Yesterday it was a sagebrush. On other days, it’s been me. And there’s the lesson. By marching straight in on a bird, we are effectively blocking our dog’s line of sight. Holding a point with adrenaline flowing and guns blazing is hard enough. It’s understandable that any smart dog would want to know where the flying bird is headed – after all, if things go well, you’ll be asking him to “fetch it up.”
