• Docs Blue Rock (1977) has a localized progeny record concentrated primarily within working ranch, team penning, and sorting lines. Because he served as a regional foundation stallion rather than a high-volume commercial breeding sire, his official American Quarter Horse Association (AQHA) offspring count is modest.

Notable offspring and down-line descendants carrying his traits include:

• Betsy Blue Rock: A direct daughter known for producing sturdy, cow-sense-heavy ranch horses.
• Kings Doc Dun: A performer and line descendant who found success in sorting, team penning, and versatility ranch events.
• Blue Rock Montana: A lineage variant often tracked closely by breeders emphasizing his distinct bone structure and disposition.
