I have found out that application forms & ethics forms can be downloaded from thecavalierclub.co.uk website.
Go into The Club on the menu & then click Membership.
Joint membership is only £2 more than single, gives two votes, & friends can be joint members as long as only one address is given.
People do not have to own a dog.
As I am already a member I would also be happy to help with this.
Best wishes to you all.
