hi my 12 week old puppy still keeps biting me and tha rest  of the family i keep telling her no and if she carries on i put her in another room but  it doesnt work she will start biting again any advice would be great thanks

Be calm and consistent and she will learn. We humans expect dogs to 'unlearn' many things that they are 'hard-wired' to do, and it takes them time. This 'biting' will usually have died away by about 6 months. In the meantime, make a note of the circumstances in which she does it (is it during rough games, etc) and prevent the circumstances happening - don't let her get too wound up!

At 12 weeks the pup will probably be mouthing alot. They naturally investigate things with their mouths, plus as the pup will be teething chewing will be a nessecary evil. You have to say 'OW!' very loudly everytime the pup acts this way and make a point of standing firm, nose in the air, ignoring her completely so she knows that behaviour won't be tolerated.  Puppy teeth can be like needles, very sharp. I doubt at 12 weeks she is biting in an aggressive way. Make sure she has plenty of safe chewable toys. 

Not many dogs acutally understand the word 'no' - most simply learn that whatever they were doing made their owners angry or started them behaving in an unpredictable way.......
IMHO it's far better to remove yourslef by simply walking away, then to give the puppy more attention by picking it up and then ignoring it - so much happens between the action you dislike (puppy mouthing) and being ignored that the pup can't make any connection :(
