Abstract
Common skin diseases (CSD) were compared and discussed in 1,407 dogs, 178 cats, and 24,657 human patients in dermatology services in approximately 6 years. CSDs shared by both dogs and humans were seborrheic dermatitis, atopic dermatitis, and scabies, and CSDs shared by both cats and humans were dermatitis and dermatophytosis. On the other hand, human CSDs not shared by dogs and cats were contact dermatitis, viral infections, and nevus. Although the terminology, definitions, and general concepts of skin diseases are not quite unified, the value of comparative dermatology, particularly in the abovementioned diseases was indicated.
