RE: Sorry but More puppy questions
Have you been crate training him? I just picked up my French Brittany a week ago, he was 7 weeks, so I have been going through much the same. Although mine doesn't bark.
On the biting thing I have just been saying "Ouch" kind of luder like it is painful and he stops. I was reading somewhere they learn not to bite hard from their littermates so since he was taken prematurely from that stage, you have to become that with him.
