If you own a cavalier-- you can join the CKCSC,USA. Pet owners, show breeders, people who got rescue cavaliers are members of this club. In the ACKCSC, you need two sponsers and you will be voted in OR NOT. Many people don't join that club because you can show in the AKC without belonging to the breed club.
Thanks, Sandy. That is very interesting to know. Does this include pets that are spayed/neutered also?
