Approach birds from anywhere but alongside your dog. You’ll see steadier points and birds that are more likely to fly than run.
I was again reminded of how working with our dogs, thinking like they think, can produce better shooting from us. In South Dakota, a companion got so nervous (or was he dazzled at Buddy’s performance?) the bird had ample opportunity to fly wild or scoot out from under Buddy’s point.
Luckily the bird held and the outcome was fatal for him. And the lesson will definitely be in my upcoming book. You can preview it here:
First, ensure a solid point and a bird that holds still rather than a scampering off unscathed. Start by being punctual. Once your dog stands the bird, walk in with alacrity. The longer you dawdle, or admire his stunning good looks, or take photos, then the greater the chance a bird will flush wild, run off or the dog will do the flushing for you.
Then, assert yourself. Over many years in many fields one thing is clear: both birds and dogs hold better when the gunner moves with confidence. Once your dog shows you the bird, stride right in and everyone will likely do what’s expected of them. No sneaking, mincing or doubt … this is the time to show you are in charge.
Choose your route with care. Swing wide around the dog and you’ll cut off one of the bird’s escape routes. Two gunners performing a pincer movement means even fewer bolt-holes for a cunning rooster more inclined sprint than fly.
Flanking your dog also minimizes his chance of breaking point. “Allelomimetic behavior” is a highfalutin’ word for the actions of that flock of birds that jinks in unison, or pair of wolves on the hunt, trotting in parallel. Sauntering close alongside a pointing dog is an invitation to follow you into the flush – that’s how we teach “heel,” after all.

I take a lot of photos of my guys while training, I think it helps them become steady to wing since they have to hold point while I’m snapping pictures. But then I’m working with carded birds so I can do it. Not while hunting. As for approaching the birds, like you said I never approach alongside my guys, I approach in the direction I want the bird to fall, usually flushing them upwind and away from cover.
Aside from that, Mia earned her AKC Jr. Hunt title in September, passing her first 4 tests, and we’ve also got a new pup that’s taking up all our spare time – I’ll start working with him after the first of the year.
And good luck!
