The urinary excretion of free, total and non-dialyzable hydroxyproline appeared to be similar in both chondrodysplastic and non-chondrodysplastic Alaskan Malamutes of ages six and twenty-six weeks suggesting the metabolic defect was probably not related to a gross disturbance in collagen metabolism. Urinary hexuronic acids also appeared to be similar in levels for both populations. A four-fold increase in urinary mucopolysaccharide levels observed at age twenty-six weeks in the chondrodysplastic Alaskan Malamute suggested a deviation from normal. The magnitude and variability of deviation were not sufficient to indicate that this condition could serve as a model for the mucopolysaccharidosis of man but probably indicated a delayed maturation process.
