contact some people at the German wirehair pointer club of northern Ca. I purchased my dog from Lynn Sandor, from the Wildwings kennel 10 years ago...been a flat out awesome dog. as for Drahthaar vs GWP remember there is very little difference. a Drahthaar is a GWP with a dutch ancestory, geneticaly they are the same. i have owned dogs that were considered a Drahthaar and dogs that were registered GWP and if they were sitting next to each other you would not be able to tell them apart. As far as AKC is concerned they are the same breed. (real hardcore Drahthaar fans will argue against this...and they may have some legitimate points)
anyway..long and short here is a good resource. http://www.gwpcnc.9f.com
like i said, I have owned a couple and would never own anything different. Awesome as a pointer and great in the duck blind. Super with my kids, mellow, doesnt bark, love my GWP's. My 10 year old dog (Roosevelt) is still going strong but I am going to start looking for a puppy, preferrably one that has some of my dogs ancestory...i know his sisters have had a couple litters...going to try and chase some paperwork and find another one.
