Yes, but they almost ALWAYS come from people who train, work with, and titled
working line dogs. For example, once at the pet store a random man came up to me and told me Kenya looks just like a bitch his friend had with them in Vietnam (military dog). Saturday we did a temperament test but it was at a SchH/police dog club and all the guys there were very nice to me and complimented Kenya. I've also had people tap my shoulder at AKC shows and tell me "that's how a GSD is supposed to look!" Sometimes I get non-GSD people who never knew sables existed praise her coloring. Non-dog people usually compliment her temperament - how calm, controlled, and obedient she is in public and busy places.
Honestly, Coke, our mutt, gets the most compliments as far as looks. It's funny how many people ask me if Kenya is a mix and then ask what breed Coke is. He is a mutt, but I tell them if they really like his looks, to check out the Hovawart because he looks just like one. He has such a sleek, lush coat and rich black and red coloring. He is also a lot more outgoing than Kenya, so he is the first to approach new people and if strangers ask to pet the dogs, we usually have them pet Coke first because he is more resilient to strange behavior. If they pass the "Coke" test, then they are allowed to pet Kenya
