Hi I Am new to this site and so relieved to find out that this is normal behaviour, starting to think that I had the most vicious dog in the world, even though deep down I knew it is normal behaviour as had researched getting puppy for many years and expected it.. We have an 8 and a half week old lab, she is absolutely gorgeous and is really good at toileting, eating sleeping etc but her nipping is her down side. Have followed the tips of shouting no, down etc, saying ow out loud so she knows she has hurt us and also ignoring her but the main problem is once she has hold she won't let go. Got a kong toy yesterday and hoping to distract her with that. How long does this phase usually last, we have 3 children and obviously don't leave them alone with her, they quite nervous that she will bite and hurt them, although youngest two don't really fuss her too much just eldest as she dog mad and has received few nipps on end of pjs and toes.
