Where size matters...
ThundeRun Australian Shepherds are bred to the CKC standard and registered with the Canadian Kennel Club as well as being eligible to register with the American Kennel Club and the Austrailain Shepherd Club of America. To be legally sold as purebred stock, animals must be registered or must be eligible to be registered with an authorized registry.
Minis or toy aussies are not considered as purebred dogs by the CKC/ASCA/AKC and/or UKC registries. Therefore, they cannot be verified as purebred and are not considered Australian Shepherds.
Please, check out your sources thoroughly and be sure of the breed you really want.
Plans are underway for a 2014 fall litter.
