It is best to allow the dog space where they will not be distrubed when enjoying a bone. I like that this parent is setting some boundary but then ....allows not such good interaction. Let me ask you....if you are enjoying a FANTASTIC meal...do you want to be disturbed? This dog checks in with Mom and then bucks the baby off. What do you think happened next? Who's fault is it if the baby got hurt when bucked off? Preventing these situations is safes tfor all.
