Personally I think the "need" for an upland pointing dog is greatly exaggerated. Flushing dogs are just as much fun to watch and just as productive ... more productive if the birds are jumpy. I must admit my pointing Lab is the best of both worlds. Tough enough for the worst conditions, can handle cold water, long legged and lean she can last all day chasing pheasants, rock solid on point, very close working (+++), unbelievable marking downed birds, anxious to please. Take out the pointing bit and she'd still be outstanding.
I think the mistake many people getting into this game make is thinking retreivers are only good for that. Wrong! Flushing dogs are fun to hunt over. It's exciting when they get birdy. At some point the rooster is going in the air, you just don't know exactly when or where. Suddenly up it goes and you have to ID it and get on it before the bird is out of range. That kind of shooting separates the men from the boys! Much more so than walking up on a dog on point, adjusting your feet, tipping back your hat, pulling off sunglasses, changing barrel selection, and waiting ... and waiting. Finally up goes the bird. An idiot can make the shot.
