Retrospective Study of 45 Dogs Diagnosed with Urticaria

Abstract

Forty-five dogs diagnosed with urticaria and treated at an animal hospital in Fukui-shi from June 2018 to January 2014 were analyzed. The following factors were included in the analysis: breed, sex, age, clinical symptoms, trigger factors, medical history, treatment, and progress. The incidence of the disease in the present study was 0.3% (45/14, 312). French bulldogs showed the highest incidence of any breed at 1.3%. The incidence in females was 2.1 times higher than that in males, and the incidence in contraceptive females was 2.5 times higher than that in non-contraceptive females. The average age was 5.2 years. The incidence in younger age animals was higher than that in older age animals. Clinical symptoms, such as angioedema of the eyelids and lips, were observed in 35 of 45 dogs with urticaria. The trigger could not be identified in 20 dogs (44.4%). In contrast, urticaria triggered by a change in side meal or staple food was identified in 14 dogs (31.1%), and by a combination of vaccines, plants, and drugs . The medical histories included atopy and allergic dermatitis (n = 18 : 40.0%), immune-mediated diseases (n = 3 : 6.7%), and recurrent urticaria (n = 5 : 11.1%). There were 19 (42.2%) dogs without any relevant history.
