i agree & it doesn't matter what the breed or the job, almost none of the modern show dogs look like the original working stock but most modern working stock does look like the original. i think that goes back to original dog shows being a showcase for working dogs. i disagree. there is a shift to a heavier built dog that i think parallels the working focus shifting from stock to manwork. but if you compare the original stock dogs to modern breeds/lines that fill the same role like mcnab, aussie smithfields, ranchbred queensland heelers, smooth BCs, kelpies & coolies (important to note in Oz they are commonly called german koolies), you can see the early GSDs pictured fit VERY comfortably w/ that crowd compared to dogs bred for manwork.
