Little kids are often confused when they see my bull terrier. They say "Look at that horsey!" or "Moo" when they see her. Once, I got stopped on the street by someone from Africa - he could not believe that the creature before his eyes is a dog. Here are some photos that confirm that it is indeed very easy to get confused. :)
