Aylesbury area puppy clubs - socialisation/obedience?

Ok a quick plea for help - have now moved to the Calvert Green area, and need to find a couple of puppy clubs so that I can continue my dog training course.

Can anyone recommend any that they have used or know of? I'm about 7 miles from bicester, about 10 from aylesbury, and everything in between!

Cheers,
Chris
