The National Whippet Club of Canada provides information about this breed and hosts the annual Canadian National Whippet Dog Show. You are welcome to become a member (but it not necessary to enjoy the site, participate in shows or trials or to just own your own Whippet!)
The Whippet Club of America is very similar to the Canadian Whippet Club.
The Canadian Kennel Club has information available about the breed standard. The CKC provides a registry for all purebred dogs in this country.
