PREVALENCE OF CYSTINE AND URATE UROLITHS IN BULLDOGS AND URATE UROLITHS IN DALMATIANS

Data were evaluated from all dogs admitted to the University of Minnes ota Veterinary Teaching Hospital (UMVTH) between June 1, 1981 and Dec 31, 1991. During this period, uroliths were retrieved and analyzed fro m 452 of 37,574 dogs admitted. The odds that uroliths from Bulldogs we re composed of cystine were 32.3 times greater than for other breeds e valuated. The odds that a Bulldog admitted was affected with cystine u roliths were 154.1 times greater than for other breeds. Cystine urolit hs were retrieved only from male Bulldogs. The odds that uroliths from Bulldogs were composed of urate were 7.9 times greater than for other breeds. The odds that a Bulldog admitted was affected with urate urol iths were 43.0 times greater than for other breeds. Male Bulldogs were 14.3 times more likely to be affected with urate uroliths than were f emales. The odds that uroliths from Dalmatians were composed of urate were 228.9 times greater than for other breeds. The odds that a Dalmat ian admitted was affected with urate uroliths were 122.4 times greater than for other breeds. Male Dalmatians were 16.4 times more likely to be affected with urate uroliths than were females. Data also were eva luated from files of canine uroliths submitted to the Minnesota Urolit h Center for quantitative mineral analysis between June 1, 1981 and De c 31, 1991. During this period, 94 of 11,188 uroliths analyzed were ob tained from Bulldogs and 387 were obtained from Dalmatians. The odds t hat uroliths retrieved from Bulldogs were composed of cystine were 40. 7 times greater than for other breeds. Cystine uroliths were retrieved only from male Bulldogs. The odds that uroliths retrieved from Bulldo gs were composed of urate were 16.4 times greater than for other breed s. Although 88.6% of urate uroliths were retrieved from male Bulldogs, the odds ratios for males were not significantly different than for f emales. The odds that uroliths retrieved from Dalmatians were composed of urate were 162.4 times greater than for other breeds. Although 93. 0% of urate uroliths were retrieved from male Dalmatians, the odds rat io for males was not significantly different than for females.
