EVERY puppy bites so dont worry and think you have some sort of aggressive , uncontrollable dog on your hands . It is usually called mouthing and is perfectly nomal . They will bite fingers, hands, toes, shoes , generally anything they can and some breeds are more renowned for it than others .
I do sympathise as those litle needle sharp teeth can really hurt . I know when my Staffy Gus was smaller we went through a period when we couldnt even stroke him without being bitten to death .
You need to start leting him know straight away that its not acceptable behaviour. Yell "OUCH" when he does it as if he was still with the rest of thelitter they would yelp loudly . Do this everytime and remain consistant . It will stop with time :)
