Missy is really aggravating my family especially my mom every time someone hugs me she has to join in. When company comes over she jumps all over them and makes her strange noises(not sure what to call it sounds like she's trying to talk) and it's really a problem because I have small nephews that come over a lot she knows not to jump on them but she gets in their face and makes her noises which scare them (my two younger nephews are scared of dogs.) When my nephews are running around screaming I have to put her up because I'm scared she's going to bite them. Also when I'm rough housing with my family or where just playing around hitting each other she gets really protective over me. She starts barking she'll even mouth them(wouldn't call it biting). Lately its gotten worse she always has to be in between me and who ever I'm talking to, hugging, sitting beside. How do I correct these behaviors.
