I would have had to ask what about her made them think she was a shar pei. Or asked them what they think a shar pei looks like.

Finn always got golden retriever. Not as much anymore, but all the time when he's a puppy. Other than that, people just ask if he's mixed with something. He definitely doesn't look like the usual lab, just because it seems like so many labs are overweight.

I can't think of any really odd guesses...

A little boy in the apartments I just moved from always said Freckles was a chihuahua. She's 20 pounds.
