What does canine ringworm look like? - briefly
Canine ringworm is often characterized by circular patches of hair loss on the dog's body, typically with a red or inflamed base. These lesions are usually itchy and may appear as raised bumps or scaly skin before hair loss occurs.

Canine ringworm, also known as dermatophytosis, is a fungal infection that affects the skin, hair, and sometimes nails of dogs. It is highly contagious and can be transmitted to humans and other animals. The appearance of canine ringworm varies depending on the stage of infection and the breed of dog, but several distinct features can help identify it.
Initially, canine ringworm may manifest as small, red bumps or patches on the skin, often accompanied by hair loss. These lesions are typically circular in shape, giving rise to the term "ringworm." The center of these circles may appear lighter or scaly due to the fungal infection disrupting the normal growth and pigmentation of the hair follicles.
As the infection progresses, the affected areas can become more pronounced and enlarged. The skin may become inflamed, red, and itchy, leading to persistent scratching or biting by the dog. This can result in secondary bacterial infections, which further complicate the condition. In some cases, the hair loss can be extensive, with large patches of bald skin visible on various parts of the body.
The fungal infection can also affect the nails, causing them to become brittle, thickened, or discolored. In severe cases, the nails may even fall off. Additionally, the skin around the infected areas may appear crusty or scaly, with a distinctive musty odor that is often associated with fungal infections.
It's important to note that not all dogs will exhibit these symptoms, and some may only show mild signs of infection. However, even in subclinical cases where the dog appears healthy, it can still be a carrier and transmit the infection to other animals or humans.
Diagnosis typically involves a combination of physical examination, microscopic analysis of skin scrapings, and sometimes fungal cultures to confirm the presence of the dermatophyte fungi responsible for ringworm. Early detection and treatment are crucial to prevent the spread of the infection and minimize discomfort for the affected dog.
In summary, canine ringworm presents with a range of symptoms including circular areas of hair loss, redness, inflammation, itching, crusty skin, nail changes, and a distinctive odor. Prompt identification and appropriate treatment are essential to manage this common but contagious fungal infection in dogs.
