Herding includes the ability to milk cows, sheep, goats and so on. Mustering is a skill at gathering scattered animals together, including for such things as branding, shearing, feeding or droving to another location. Those attempting to herd animals without this skill will find themselves frustrated to bring animals together and will consistently lose 2-5% of their herds weekly to preying animals, accidents or disappearances.
Dogs are helpful in herding animals but this ability gives no special skills in managing or directing dogs. That knowledge must come from elsewhere.
