and, you're assuming the mugler is dog savvy and would recognize the dobe up close for what it is just uncropped
I've had both cropped and uncropped dobes out in public, and the general public out there, no doubt about it two completely opposite reactions! With the cropped I literally had people crossing the street to the other side walk, people refusing to get in the elevator with us, one guy in the condo literally jumped and screamed and tucked himself up against the wall (I am not exagurating!). There were the odd few who would say, oh I love dobermans can I say hi to him, but the over whelming reaction was fear and distrust.
When I had the uncropped dobe with me, while some people would still be fearful (some people are afraid of big dogs regardless of what it is), it wasn't the same sort of reaction. Some people would start up conversations, oh what a pretty dog, she listens so well, what is she? Not too many people knew she was a dobe. When I told them, some would just say oh really?, some would say oh.. and stop petting her
Don't underestimate the lack of dog knowledge in the general public. You might look at an uncropped dobe and think, duuuh, ofcourse it's a dobe! Other people just see a large houndy looking mutt.
