I have to give a huge shout out to the Rocky Mountain German Shorthair Pointer Rescue, Penrose, CO.
I adopted my GSP 2 years ago and he is an incredible dog. I visted the rescue yesterday to show off my boy and to see the !puppies! Kris has right now. Unfortunately, she has a lot of them: GSP/mix pups that look like GSPs, GSP pups that don't and are much more mellow, and some awesome GSP/English pointer pups.
Of course, there are lots of adult dogs for adoptions as well. She focuses on on German Shorthair Pointers but often has other breeds or mixes as well.
If you are an active, outdoor-sy person looking for an awesome dog to spend time with, check it out:
