Uncle Buddy is the example: now, to approach strategically so he holds still on the flush.
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.”

I totally agree Scott, but also add coming up behind a dog on point can give the dog added pressure. Be it a person or another dog. His reward is retrieving the bird, if the dog thinks or feels that he is going to be cheated out of the reward by a another dog that bust his point and runs past him he’s not going to hold. The other consideration is pressure from us, and how we train. “What my dog taught me” lol 🙂 is that when we are training especially when by yourself to come from the side of the dog instead of from behind. Dogs learn most things thru site, they need to see you and your commands or body language along with hearing and repetition. If you have a dog and it creaps, or points really close and you come up from behind stand over top which is a dominate posture and reposition him further back, if that correction is always coming from behind no matter how gentle, sutle or slight they dog may start to sling or coward down even if you are praising with happy words its still a dominate correcting posture. Its what we all have been taught and see in the videos and at seminars and never think about. I was running my first hunt tests with our 13 month old gwp was waiting up at the line for my 4th run, with having 3 out of 3 passed test and highest scores of the two days, what could possibly go wrong right. The birds for the test were stage at the front line on the ground in creates and flint wanted to get to them of course, nudging the crate of birds, so what do I do come up behind him very calm and casual and said no bird softly and pulled him away. The team before us comes in and it’s our turn flint has already caught on to the game and is all business an slammed the first point as I start to walk toward him from behind without a word he starts to lower but doesn’t bust, the closer I come he lowers 1 inch at a time. At the time I didn’t know why but new that he felt pressure from me coming up from behind him. I was dumb founded and at a loss, why is he doing that now, he has never done that before, he acted like I beat him, so we got a call back. Again flint slams the point soild, confident and stylish. I start walking up from behind he slightly drops, now what do I do I thought so I backed off he raised up, the judge motioned for me to circle around and come from the front/ side so I did. I made as wide of circle as possible I was able to get closer but then he dropped slightly, with a positive happy face and tone. I said good boy. Because he could see and hear me and the tone and watch my body language he raised up I walk in flush the bird he retrieved it and passed.
This idea got a lot of head nods at Game Fair, James, didn’t it? Great stuff.
