the problem I see with allowing a pointing breed to flush instead of point is this:

It is in a pointing dog's nature to range out and quarter a longer distance from the gun. If your dog is out of gun range, where most pointers work, and flushes a bird you will not have a shot at it. Further more if you attempt to hold the dog in gun range you are going fighting trates that have been bred into the dog for gerartions.

good luck if it is what want to do but advise is what you came here for so mine is if you want to train this dog train it to be a pointing dog like it was designed.
