Hi there, I have a 19 month old border collie mix. She's not a big fan of people but she never shows aggression and will approach people but shies away from being touched by most strangers. She'll play ball with them all day long but won't approach a person she doesn't know well for any sort of physical contact. She will play games with children but same deal, doesn't want to be pet by them. We've noticed some very strange behavior with kids though. If a child is picked up by a parent the dog seems to get very anxious and will start barking and jumping up and nipping around the child being held by the parent. She'll also show the same reaction if a parent or adult hugs a child or is in close physical contact with the child. Anyone have any thoughts or ideas as to how I should deal with this behavior or why the dog is exhibiting this sort of behavior around a child? Thanks in advance for any feedback.
