I laughed when I read your reply.. If you wait 6 more months to jump on her and nibble on her ear and make her cry out; "stop mommy" she may rule the house..
At 4 months you should correct her - then praise her when she act's the correct way you wish, you will gain her respect. Pounce, nibble, listen, cover your face.. Oops, did I just suggest you dominate your dog to protect your daughter's beautiful cheeks, you bet I did..!!
