This study was conducted to investigate the clinical data of two cases of canine sialolithiasis and to analyze 29 cases identified in the Veterinary Medical Database by year of admission, breed, gender, and age. Medical records from the University of Missouri Veterinary Medical Teaching Hospital were reviewed and two dogs diagnosed with sialolithiasis (calcium oxalate) were identified between 1990 and 2010. The two dogs had cervical or pharyngeal sialocele and were successfully treated by sialolith removal and concurrent sialoadenectomy. Signalments of dogs with sialolithiasis between 1964 and 2010 were collected from the Veterinary Medical Database and evaluated. Several breeds of dogs were represented and the 10 to <15 yr old age group was shown to have significant association with sialolithiasis. Sialolithiasis is a rare veterinary condition. In this study, older dogs were at higher risk. In dogs, concurrent sialocele was common and good outcome could be expected after surgical removal of sialoliths with concurrent sialoadenectomy.
