Abstract: Dermatomycosis are common zoonotic diseases that affect the health of animals and humans while affecting appearance. In this study, the disease condition of canines and felines in Taixing's three pet hospitals who were diagnosed with dermatomycosis from November 2020 to October 2021 were investigated and analyzed. The relationships between dermatomycosis of canines and felines in Taixing and factors such as season, sex, age, breed, hair length and so on have been illustrated. The results showed that three pet hospitals in Taixing received a total of 2 008 cases in one year, in which canines and felines with dermatomycosis were 371 cases, accounting for 18.48% of the total cases. Summer was the peak period of the incidence, and the incidence rate accounted for 53.10% of the whole year. The winter incidence was low at 3.77%. The incidence of canines and felines under the age of one was higher than that of other ages, 58.17% and 77.06% respectively. The infection sites were mainly in the abdomen and extremities in canines, and around the eyes and ears in felines. The female-to-male ratio of affected canines was 82∶71, and the female-to-male ratio of affected felines was 89:129. Poodles and British Shorthairs were the common diseased breeds, with incidence rates of 28.10% and 44.50% respectively. These data provide a reference for the prevention and control of dermatomycosis in canines and felines.
