Ringworm (Dermatophytosis) in Dogs
Ringworm (Dermatophytosis) is a low-severity dermatological condition that can affect dogs of all ages and breeds. Ringworm is a fungal infection of the skin, hair, and nails caused by Microsporum or Trichophyton species. Despite the name it is not caused by a worm. It is highly contagious to other animals and humans (zoonosis), making management important. It is documented across 3 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at Young animals and immunocompromised individuals. Early signs to watch for include circular patches of hair loss, scaling and crusting, mild itching, and broken hairs. When treatment is required, costs are estimated at £300-£800 depending on severity, location, and the specific intervention needed. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
