We conducted the following analysis to understand the epidemiologic features of domestic dogs, histologically diagnosed tumors, and the crude incidence of tumors in Gifu prefecture, between April 2013 and March 2014. Among the tumor reports of 33.6% of animal hospitals in Gifu prefecture, we analyzed 731 diagnostic cases. We adjusted the number of domestic dogs and tumor cases by the response rate to the questionnaire, and then calculated the crude incidence of tumors and the crude incidence of malignant tumors. The crude incidence of tumors was 1.5% and the crude incidence of malignant tumors was 0.6%. In addition, the crude incidence of tumors (crude incidence of malignant tumors) was significantly (P<0.05) higher in Dachshunds at 2.6% (1.3%), Shih Tzus at 2.4%, Schnauzers at 2.5% (1.4%), Pugs at 3.8% (1.9%), Welsh corgis at 3.3% (2.2%), Beagles at 2.2% (1.4%), French bulldogs at 3.2% (1.3%), Shetland sheepdogs at 3.2%, Labrador retrievers at 3.2% (2.5%), Golden retrievers at 2.7% (2.2%) and Bernese mountain dogs at 8.2% (7.1%) than in all breeds. In contrast, the crude incidence of tumors (crude incidence of malignant tumors) was significantly (P<0.05) lower in Poodles at 1.1% (0.3%), Chihuahuas at 0.5% (0.3%), Pomeranians at 0.9%, Shibas at 0.7% (0.3%) and Mixed breeds at 1.0% (0.6%) than in all breeds.
