Ringworm in canines manifests as a fungal infection of the skin, hair, and nails. Its appearance is not always characterized by a circular, ring-shaped lesion, despite its name. Instead, it commonly presents as areas of hair loss, scaling, and inflammation. Lesions may appear as dry, scaly patches, often with broken hairs at the periphery. In some cases, pustules or raised bumps might be observed. The affected areas are typically itchy, leading the dog to scratch and potentially spread the infection to other parts of its body or to humans and other animals.
Accurate identification of the infection is important for prompt treatment, minimizing discomfort for the affected animal and preventing further transmission. The infection can persist for an extended period if left untreated, causing chronic skin problems and potential secondary bacterial infections. Historical understanding of this dermatophyte infection has improved diagnostic methods, allowing for more effective treatment strategies. These strategies aim to eliminate the fungus and restore the health of the skin and coat.
