The Miniature American Shepherd Club of the USA, Inc. (MASCUSA) is the American Kennel Club Parent Club for the Miniature American Shepherd. MASCUSA ended their registry services in 2016 but the AKC studbook for this breed remains open. MASCSUA entered into a contract with Stock Dog Registry Services to continue the registry services that had previously been provided by the club. Stock Dog Registry Services is the only registry selected by MASCUSA through which dogs can be registered with AKC.
Stock Dog Registry Services was founded in 2016 to provide a pedigree verification process for dogs entering the American Kennel Club as Miniature American Shepherds (MAS) as well as registering litters for offspring of various crosses that wish to enter AKC.

Please see the AKC Registration page for the acceptable registries and current rules and requirements.

As of 12/31/14 Australian Shepherds may no longer register as Miniature American Shepherds. 

A dog cannot have an Australian Shepherd as a parent regardless if the parent has been registered as a Mini Aussie.

Important upcoming dates for the closing of the studbooks

The AKC Miniature American Shepherd stud book will be closing officially on January 1, 2025.

The studbook closing does not affect any AKC to AKC Miniature American Shepherd litters. They are still registered through AKC.


SDRS will accept litter applications for puppies that are whelped on or before June 30, 2024 from crosses from eligible approved registries.

All applications for litters must be postmarked or emailed to SDRS by August 1, 2024 or they will not be processed.

No litter application for any puppies whelped after the June 30, 2024 date will be accepted.

Anyone who has puppy papers issued by SDRS must submit them to SDRS by December 15, 2026 or the puppy paper will become void.

Breeders, please make sure your puppy owners are aware of this date.
