I am almost sure that Lucy would not bite anyone, but I still don't feel comfortable letting some people pet her. You just never know what they are going to do. We have an airbrush business at a mall in a kiosk and I see really crazy stuff all day. One lady was walking her sweet little long haired chihuahua puppy and a mother asked if her little girl could pet the puppy, the woman with the pup said yes and the girl went up to the pup and slapped it with all her might. The mother started to laugh - I sort of let the mother know what I thought. But you never know what people are going to do, or really know what your dog might do. Heck, I got my nose rearranged by the grandson of Lasie when I was ten. Lucy hates the guy that mows the lawn and he loves dogs. Even when the the two terriers were falling all over themselves to get him to pet them, Lucy was trotting around him in a wide circle growling. I was so shocked. He is the only person I have ever seen her not like, she isn't even bothered by the people mumbling to themselves on street corners. I feel mean when I don't let people pet her. I'm just curious what others think or do.
