Mature Kerry Blues will grow to a height in between 17 and 20 inches and weigh I between 33 and 40 pounds.
Males tend to be a bit larger than females.
Coat colors range from blue-gray to dark gray, though pups are born black. Their coats require regular grooming and an occasional professional trim.
