Good puppy classes in Chelmsford/Essex area?

As you may have seen from my other posts, we are just about to take home an 11 week old Doberman girl. I am very keen on getting her along to puppy parties and classes as soon as possible for the socialisation. Does anybody have any recommendations in the Chelmsford, Essex area? Google comes up with a couple but it's always better to go on recommendations...

I know a few I wouldn`t recommend but obviously I`m not going to put them on the forum!
Can personally recommend these two though...

or

(avoid sundays with that one - gets overcrowded)

I`ve heard that Waggybums is good but haven`t been to it.

I`ve tried most of them... heck, I`ve been thrown out of some and walked out of more... so pm me if you have seen one you like

I can personally recommend Gary and Caroline, both lovely people
