Like I said in my earlier post, some guys don't understand what you're working to accomplish and can't hold back on birds a young dog will bust. I won't take those guys hunting when I'm in the early years with a young dog. But that one season, or part of one season, it takes to get him staunch is worth watching those busted birds fly off. For a the owner of a pointing dog it's part of the program. You either accept those terms the first year out, or don't get a pointing breed.
Pheasant don't often "behave", but a smart dog will figure it out. I've had young setters in their first season point, relocate, point, several times before pinning them down. That's just good breeding and a smart dog learnign on the fly. My last pup was in his first season at 1 year and 5 months when he worked a bird over 100 yards, pointing and relocating a running bird, until he finally made a wide sweep around and locked up facing me. Pinned the old rooster between he and me. I walked in to flush and nailed a cackling rooster with close to 1", sharp as hell, spurs. The guy hunting with me was a lab guy and didn't have a close as to what kind of job that young dog had just done.
I've had a lot of pheasants hold so tight you would think there wasn't really a bird there, with all the kicking around it took to get them to fly. To say a pheasant won't hold is just not true. I've hunted behind setters for 45 years and have shot a lot of roosters over solid points. My shooting percentage is also a lot better hunting with my setters than with my buddies labs/springers, because I'm closer to the bird when it takes flight.
Ruffed grouse also run. They're masters at putting some blocking cover between you and them before busting out. A good pair of hunters that work well together helps. Pay attention to the wind and be aware of the blocking cover [normally balsam fir in the aspen understory here], make a pincer movement with one guy going around each side, gives one a decent chance.
