I couldn't tell you in your area but, the German Shorthair Club of America has a web site, I just went there. Scroll down a way's and there's site's for rescue dog's. Rescue dog's can be a good deal but you don't know what you've got for sure until you get it. I've a friend that got a Corgy thru rescue and the dog is screwed up. It was used as a brood bitch and kept in a small pen, scared to death of people. I knew a guy from Salem, Ore years ago that got a GSP thru rescue. It was a real nice dog but absolutely gun shy. Somebody really worked that one over befor getting rid of it. Sometime's you can go to field trials and pick up pup's reasonable if they're getting older. To find field trials check with GSP of Amer, National Shoot to Retrieve Assoc and in your area maybe National Bird Hunter's Assoc. All should have web sites.
Sorry I can't be of more help.
