Most the time people get it right with my two. Sometimes people will ask with Tommy, but he's a big boy and I think he looks pretty "male."

However, with my RB collie boys, people were always calling them "she," especially Cody, who had the sable "lassie" coloring. I remember one lady after I told her Cody was a male, she exclaimed "But she's too PRETTY to be a he!"

People have told us his head is so small because we got him neutered too young (6 months).
I had to LOL at that. That's one I hadn't heard before
