That's what I've found:
4 CAC (minimum 1 at international show) under 3 different judges,
between the first and last CAC, a minimum period of one year and one day must have elapsed
(CAC in Brussels = 2x 'normal' CAC)
what is CQN? And how is the qualifier?
There are other countries, where you need a working test, but in some you can use the one you need for the Interchamp - which makes more sense anyway. Those different rules are not really sensible in many ways.
Well, we will of course have to through Belgium every time we go to Britain, but for the time being we are not going - we have puppies, so no Crufts and Dublin or the Festival will not see us either as my daughter will have her first baby just then. I do have my priorities.
