I would say really think about what kind of temperament you want from your dog. This is the biggest factor on what your lifestyle will look like with your dog. A lot of people think they want a high drive dog until they actually live with a high drive dog. It can be a lot. I love my WLGSD but his energy level can be challenging at times - I'm not a kid anymore. LOL.
After you know what type of temperament you want, start searching out breeders. At a minimum you want the parents to have hips and elbows OFA certified and to be free of DM or one parent is an unaffected carrier, at most. All of the health claims will be associated with paperwork and pedigrees proving the breeders claims. Ask for copies. Also, there should be a health guarantee and a written contract for the puppy.
Good places to look are GoodDog.com and WorkingDog.com. Also, you could find local IGP training clubs, GSD clubs, get involved and ask about reputable breeders etc.
Rescues can make fantastic dogs. I've had several of different breeds. But you don't know what you're getting as far as health is concerned or temperament for that matter.
I'm not sure what type of dog you're looking for but if you're OK with going out to West Virginia or even have your pup shipped, I would recommend Vomhaushighlands. That's where my pup came from and he's the nicest dog I've ever had. Kyle is a small breeder concentrating on high drive, healthy, stable working line dogs. These might not be right for you but if they are, I couldn't recommend him more.
He answered all of my questions 100 times. Spent several hours on the phone with me, shipped my pup and didn't even want payment until the dog was delivered. Just an incredible person to do business with. I wouldn't hesitate to get another dog from him.
Mom, dad and my pup.
