Multipurpose breeds may be added to this section at the discretion of the Board based upon research showing use as a herding dog. Multipurpose breeds may also be added by the Board upon request with provision of documentation (such as breed descriptions, photos, accounts, books, etc.) showing historical use as a stock dog and current use as a stock dog, e.g., dogs engaged in practical stock work on a farm or ranch, participation in trials, etc. Serious interest in herding qualities must be shown by owners and breeders. Dogs ineligible for HCT may participate fully in all trial classes and Junior Herding Dog.
