American Shih Tzu Club The American Shih Tzu Club, Inc. (ASTC) was formed in 1963 by a small group of individuals who shared a common interest in, love for, and commitment to the Shih Tzu breed. Since then, the ASTC has continued to grow in membership, in local Shih Tzu club affiliates, and in liaisons with other Shih Tzu organizations throughout the world. The ASTC is a member club of the American Kennel Club. in Bookmarks Toolbar > Teris Links > Other Miscwith americanastcclubincmiscshihteristzu
