First off, are you on a team? My recommendation is to get on the team, get active as there is a lot of non-dog stuff to get through first and that will help open contacts for getting a good dog .......... Depending on where you are, some teams won't even let you bring a dog onto the team for up to a year or more.............
I think most of the good breeders of dogs you would want to do SAR are going to want some knowledge that their puppy is likely to reach the training goals.....Border Collies often make good SAR dogs...may be good to get on a team, do some training on the collie so you can make your mistakes there, then when you are ready, get the GSD pup.
