dogsaver...I noticed your confusion about the shelter labels. ALOT of shelter automatically put the "mix" there....for a variety of reasons...namely...because these are dogs they usually have little background on. Don't go by the shelter label. Use your eye. Many times there are even GSD's labeled some other breed.
Don't I know! I thought it was pretty likely that this one was pure but always like to get the experts' input. Posted one earlier today (can't think of the name) that was listed as a collie (only one pic of her from the front sitting) that I knew had to be a GS; everyone seems to think it's a long haired pup. There was another one "Canton OH #05" that had a perfect GS head and profile but the body was iffy; posted it and most seemed to think it was pure; then noticed today the shelter site said adopted.
