Most the GSP ive come across just lose the plot and run about clearing game from a 5 sq mile area, ( I know there are some good ones but not many).
That says more about the trainer/hunter than the dog in most cases. The 2 GSP I know will out hunt every other dog in camp (15 in camp is not uncommon.) They are not my dogs, so I have no ego on the line here. I'll conceed that the hard work is front loaded, and the trainer/owner spent an obsene amount of time and patience preparing the dogs. I've seen some good English Setters (by the same trainer/owner), but they can't hold a candle to the GPS.
