A blue heeler gets as big as 20 inches in height and 50 pounds in weight.
Male blue heelers typically stand at around 18-20 inches at the shoulder, while females are smaller at 17-19 inches.
Adult males usually weigh between 35 and 50lbs, while females rarely weigh more than 45lbs.
Their size depends on a combination of genetics, diet, and how much exercise they get when they’re growing.
Despite being medium-sized dogs, blue heelers are very muscular and surprisingly strong.
