The appearance of dermatophytosis, a fungal infection commonly affecting canines, can vary significantly. Affected areas may exhibit circular patches of hair loss, often accompanied by scaling, crusting, and inflammation. The lesions are not always ring-shaped, despite the name. Sometimes, it manifests as localized areas of broken hairs or generalized dandruff. In severe cases, deeper infections called kerions can develop, presenting as raised, nodular lesions that may drain fluid.
Accurate identification of this condition is crucial for prompt treatment and prevention of further spread. Early intervention minimizes discomfort for the animal and reduces the risk of transmission to other pets or humans. Historically, diagnosis relied heavily on visual examination and fungal culture, however, newer diagnostic tools have increased speed and accuracy. The benefit of understanding the diverse presentations of dermatophytosis in canines is improved animal welfare and public health.
