As a dog lover I don't find that offensive at all.

As the mother of a child who used to do these things I do find what you said about that child offensive, both to that particular child and to his parents. Like I said in my previous post, the only thing YOU can do to protect your dd (because she is too young to protect herself and to play unattended) is to be with her and teach this boy how you want him to treat your dd. That is all you can do if they are going to be associating with each other on a regular basis.
