She looks as if she could be a little older than 10 weeks, but as you have no papers there is no way of checking.

She looks all cavalier, ( prospective puppy buyers should note that a seller can show you any two adult dogs and say they are the parents, but it may not necessarily be true ) and if she has the lovely, playful, happy, cavalier temperament then hopefully you will find that it really doesn't matter whether you were misinformed a little about her age.
She looks as if she is a real sweetie, so just enjoy your baby.
Cavaliers......Tommy Tuppence 2000-2012 and a half share of Faith.
