We often get this question, as our dog looks soft and pet-able. If kids are polite enough to ask, I always try to accommodate them to reward them for doing things the right way. But our dog is a rescue and not all that fond of strangers and children, so I have her sit, get down to her level, put my arms around her, and tell the kids not to touch her head, but pet her body. See how soft she is? I ask. I think it's good for everyone, unless the kids are screaming and overly wild. Then I just say no.
