What Does Ringworm on a Dog Look Like?

Ringworm is a common skin infection that can affect dogs. Despite its name, ringworm is not caused by a worm, but by a fungus called dermatophyte. This fungus thrives in warm and humid environments, making dogs susceptible to it, especially if they have a weakened immune system or come into contact with infected animals or objects.

The appearance of ringworm on a dog can vary depending on the severity of the infection. Here are some common signs to look out for:

1. Circular patches: One of the most distinctive features of ringworm is the appearance of circular patches on a dog’s skin. These patches may be red, scaly, and have a raised border. Hair loss is often seen in the center of the patch, giving it a ring-like appearance.

2. Itchiness: Dogs with ringworm may experience itchiness, which can lead to excessive scratching, licking, and biting of the affected area. This can further aggravate the infection and cause secondary skin problems.

3. Crusts and sores: In severe cases of ringworm, crusts and sores may develop on the affected skin. These can be painful for the dog and may ooze or become infected.

4. Dull and brittle hair: Infected hair may appear dull and brittle, and it may break easily. Hair loss can occur in small patches or be more widespread.

5. Thickened or discolored nails: In some cases, ringworm can affect a dog’s nails, causing them to become thickened, brittle, or discolored. The nails may also separate from the nail bed.

6. Facial involvement: Ringworm can affect any part of a dog’s body, but it is more commonly seen on the face, ears, paws, and tail. These areas are often more humid and provide an ideal environment for the fungus to thrive.

7. Spreading to humans: It’s important to note that ringworm is zoonotic, meaning it can be transmitted from animals to humans. If a dog has ringworm, it’s crucial to take precautions such as wearing gloves when handling the dog and thoroughly washing hands and any other exposed areas after contact.

8. Diagnosis by a veterinarian: If you suspect your dog has ringworm, it’s vital to consult a veterinarian for a proper diagnosis. They can perform tests such as a fungal culture or microscopic examination to confirm the presence of the fungus.
