Interesting reading other people's experiences. I hope I didn't give the wrong impression about my friend. She is a very experienced pointer lady and has been in the breed many years and does put a lot of time into their training.
The dog who is the worst culprit is trained up to KCGC Gold and the most delightful dog you could know. Get him on the scent of something though and his nose takes over. I regularly see one of his litter brothers being exercised in the distance and the ground he covers is phenominal, swinging back to his owner in huge great circles. There is no way either of these two could be safely exercised in a normal park as the area they range over is just too large.
The bitch in question is only young but from a very early age my friend feared she was going to be like her dog so put in a huge amount of work, but she still goes deaf if on the scent of something. As mentioned previously these two are not let off lead together, but one at a time with the rest of her dogs, all of who have a good recall.
The other dogs all still run and hunt, but stay closer and respond to the whistle. Having said that I couldn't help but laugh when she was in a panic a few months ago thinking she had lost a bitch who always returns to the whistle. This time no response and some 15 minutes later when she was fearing the worst and rounding up the search party, she spotted a white flash in the long grass. Lo and behold it was the bitch pointing at a bird and as the grass was so long it had hidden her from view.
Good luck if you decide to go ahead. If it helps I will ask my friend if she would mind me passing over her contact details.
