The GSP is not just a short haired version of the GWP - they are similar but different breeds that need a different approach. Neither are breeds for novice dog trainers if you want to get the best out of them and they vary a lot in temperament and working style. They are very very slow to mature and can be incredibly headstrong. On the positive side - when well trained they are excellent. I have trained springers to a high standard and had to chuck the book away when i got into GWP's they take a certain way of handling that will blow your mind if you are used to a springer or leave you sobbing
