Plain-English summary
A group of 179 dogs with swelling in their mouths or faces were diagnosed with various salivary gland diseases over an eight-year period. The most common issue was nonspecific sialoadenitis, which is inflammation of the salivary glands, affecting nearly half of the cases. Some dogs had tumors in their salivary glands, with most being malignant. Treatment varied depending on the specific diagnosis, but many dogs were monitored or treated based on their individual conditions.

Abstract
Salivary gland diseases are well characterized in human medicine but are uncommonly reported in dogs. Herein we describe the clinical and pathologic features of 179 canine salivary gland biopsy submissions to the Athens Veterinary Diagnostic Laboratory from 2010 to 2018. The mean age of affected dogs was 8.5 y; no sex or breed predisposition was evident. The main reason for sample submission was regional swelling (107 cases; 59.7%). Extraoral (major) salivary glands were affected in 125 cases (69.8%), and oral (minor) salivary glands were affected in 43 cases (24% of cases). The location of the lesion (extraoral or oral) was not specified in 11 cases (6.1%). The diagnoses included nonspecific sialoadenitis (89 cases; 49.7%), normal salivary gland (42 cases; 23.4%), neoplasia (36 cases; 20.1%), salivary gland lipomatosis (7 cases; 3.9%), necrotizing sialometaplasia (4 cases; 2.2%), and traumatic hemorrhage (1 case; 0.5%). Most cases of sialoadenitis (63 cases), neoplasia (23 cases), and lipomatosis (5 cases), as well as all cases of necrotizing sialometaplasia and the only case of traumatic hemorrhage, affected extraoral glands. Most neoplasms (32 cases, 88.8% of the tumors) were epithelial and malignant, followed by round cell tumors (2 cases; 5.5%), a carcinosarcoma (1 case; 2.7%), and a tumor of undetermined histogenesis (1 case; 2.7%).
