I got a shaved chow-chow at a dog show once…
Our local Caesar Milan Wanna-be claims she's a stunning Pitty (while grabbing her face and pushing it up to his, as she's snarling... I kicked him in the crotch). Incidentally, he is currently in jail for animal abuse charges and for stealing aka. not giving back client's dogs after training them..
The best was when I was asked how I tamed a fox. I pointed to her tail and said after I used a curling iron, I had no other issues. This was from an Animal Control Officer that bragged about knowing every breed of dog, and having been a handler to many of the best dog shows world wide... my dry wit could not be contained!
The best positive ID came from a wheel chair bound senior in my Husband's Grandma's small town senior complex. We went to visit with Cricket, who was just sitting next to Grandma and me on the floor (we were actually trying to hide her from the nurses because we weren't sure if she was allowed there...). This older gentleman slowly wheeled up with this awed look on his face, but didn't actually say anything as he just stared at her in wonder. I jokingly asked if he was going to tell on us and get her kicked out, he said "god no, is that a real Basenji?" and he said the actual African name, which I had never heard before. I told him she was a basenji, but I had no idea what the other words were. He then told us about his trip to Africa in the early 50's as a young missionary and seeing Basenjis in the villages, how they hunted, etc. He had never seen one since. Our next visit, he had some albums out, which were amazing! I wish I knew what happened to those after he passed.
