I got Pixie at 8 months and had a problem with biting. I agree with the other post that they did not learn the biting thing from their litter mates.
When Pixie would bite me I would say No in a firm voice or ouch in a shriek and then I would stand up and turn my back on her for a few seconds. If she did it again I would repeat and if that did not work I would put her in her ex-pen for about 3 min and then let her out.
I found that once Pixie got going on that mode sometimes she couldn't stop and needed a time out in her ex-pen.
Your dog will outgrow this and the most important thing is not to show fear when he does it. Remember he is a puppy and you are in charge and he just needs to learn. I would say that it only lasted about 1 month or so and then she stopped. They hate to have you ignore them during play time, so if he starts biting just say no and stand up and turn your back on him!! Good luck!
