It doesn't happen so much anymore, as people in the area know me and my dogs. But when we first moved here I had a kid state that Keiko was a coyote. Whaaaa??!! I get asked alot if she is part wolf. I actualy have no idea what her other 1/2 is, but it's probably mostly shepherd, so I tell them probably not any wolf (I have actually met two supposed wolf crosses....... ..one wolf/husky/shep and one shep/wolf that look almost identical to her, but slightly bigger) Most people can guess the husky right way........... ..they eye gives it away. One person asked if she was part aussie.
When we got Gunther, and he was smaller, we got the usual pit, greyhound comments. After he passed 8 months old, no one has been wrong since with guessing what he is. I swear everyone I meet has either at one point had a great dane or bred great danes. I never realized how popular they were.
