Ringworm in canines manifests primarily as circular patches of hair loss, often accompanied by scaling, crusting, and inflammation. These lesions are typically found on the head, ears, paws, and tail, though they can appear anywhere on the body. While the name implies a worm infestation, this condition is actually a fungal infection of the skin, hair, and nails. The appearance can vary, sometimes presenting as mild flakiness, while in other cases, it can result in severe, inflamed sores.
Prompt identification of the characteristic skin changes associated with ringworm is important to prevent its spread to other animals and humans. It is a zoonotic disease, meaning it can be transmitted between animals and people. Early diagnosis and treatment not only alleviate discomfort for the affected dog, but also minimize the risk of contagion. Historically, recognition of fungal skin conditions in animals has been essential in managing public health concerns related to zoonotic diseases.
