I find this thread really interesting, in many ways. I'd like to see some of the big name breeders comment- as I felt the same way as you, Kristi. I know the smaller GSDs are out there. Zefra sure rocks, and as I think we've discussed in the past- Lisa Clark's dogs are on the smaller side.
I also cringe when I hear of a nice small female being breed to a much larger, more substantial male. What a shame in my opinion. I have all the same concerns about impact and wear and tear on the body. It's all reasons why I just couldn't pass up on little Jinks. But Pimg- yes, there IS wear and tear on her from agility from her weight/size. Good luck finding what you're looking for. Though they are out there- I think they are few and far between.
