I posted a thread about this on a corgi forum I am a member of. Tegan and I had a day on the town looking for things for Lyla when I first got her, and hardly anyone said "what a beautiful corgi!" they always would say "Is he a corgi mix?" "Corgi and aussie?" etc... because he's a tri color people just did not understand he was in fact pure corgi!
Then, the other day Lyla got called a Greyhound Dalmatian at the dog park which made me laugh SO hard, the girl had no idea I owned her and told her boyfriend, in a very matter of fact tone, that Lyla was a greyhound dalmatian....
Anyway, it just got me thinking, who else has funny uneducated people guessing the breeds of their dogs in the world?
