Plain-English summary
Four dogs were diagnosed with a skin infection caused by a type of fungus called Trichophyton mentagrophytes var erinacei. These dogs showed symptoms like scaling, crusting, and hair loss, primarily on their noses, with some lesions spreading to other areas of their bodies. The infection was confirmed through skin samples, but the fungal elements were often hard to detect under the microscope. Treatment details were not specified, but addressing fungal infections typically involves antifungal medications and proper skin care.

Abstract
A retrospective study of the histological features of four cases of canine Trichophyton mentagrophytes var erinacei infection is reported. In all four dogs the initial lesions affected the dorsal muzzle and in two dogs the lesions spread to more distant sites on the body. Clinically, the lesions were characterized by scaling, crusting and hair loss. Histologically, the main lesions were characterized by acanthosis, epidermal, ostial and infundibular hyperkeratosis, serocellular crusting, mural folliculitis and furunculosis. Fungal hyphae were usually sparse and often difficult to see in haematoxylin and eosin stained sections. When visible they were seen in the epidermal, ostial and infundibular scale and, less frequently, within hair shafts.
