Yes, it is pretty normal... Infact Meka is 10 mo's and she stopped doing it around 8 mo's or so. I use to have to pick her up before someone approached her, because she couldnt help herself. Then we started training her to sit/stay when someone approached us and not let them pet her right away. That way when she saw that its not all about her, she was able to calm down... Hope this helps
