Hi just moved to Christchurch, Cambridgeshire, I am looking for a ring-craft club either in Norfolk or Cambridgeshire .... anyone know of any please ..thanks

There is an excellent ringcraft class at Upwell village hall on thursday nights.

If you can't find one that does Ringcraft specifically, you should be able to find an Obedience class that lets you attend, with emphasis on ringcraft.   We did this with our hounds, using one just outside Saffron Walden.   It was years ago now.    When they all sat their dogs, we'd put ours into a stack and have the trainer 'go over' them as would happen in the ring.   The atmosphere in the class, with other dogs around, was a good education for a novice puppy too.

Your vet may be able to help you locate a good local class, other than the one already suggested here?
