Abstract: In order to know the incidence of skin diseases of pet dogs in Tianjin, an epidemiological survey was conducted on 166 cases of dogs with skin diseases admitted to a large pet hospital in Tianjin from March to June 2018, and statistical analysis was conducted from 5 aspects including breed, age, gender, pathogen and sterilization of the dogs. The results showed that there were 18 breeds of dogs, among which the incidence was 19.28% for poodles, 15.06% for Chinese pastoral dogs and 13.25% for bulldogs. The incidence of juvenile dogs under the age of 2 years was the majority, accounting for 56.02%; 2-9 years old adult dogs and middle-aged and elderly dogs were less at 22.89% and 10.24%, respectively; The incidence of elderly dogs over 10 years old was relatively high at 10.84%; Males accounted for 62.65%, more susceptible than females. Most of the cases were infectious skin diseases, mainly fungal infections, mostly mixed infections, and few other non-infectious skin diseases.
