What Does Ringworm Look Like in Dogs?

Although ringworm can sometimes be hard to spot, you’ll usually notice circular or irregular patches where your dog’s hair is missing, often with crusty or scaly skin. These hair loss spots often have grey, dandruff-like scales or scabs, and the affected skin may appear red or inflamed.
Lesions caused by ringworm commonly show up on your dog’s face, ears, paws, tail, or underbelly. The hair around these patches can become dry and brittle, making the affected areas stand out even more. Sometimes, you might even see raised nodules on the skin.
Keep in mind that some dogs carry ringworm without showing any visible symptoms, which can make it tricky to spot. So, if you notice any unusual hair loss spots or crusty skin on your dog, it’s a good idea to get it checked out. Ringworm could be the culprit and will need some attention.
How Is Ringworm Diagnosed in Dogs?

When you suspect your dog has ringworm, a veterinarian will start by closely examining the affected skin and hair. They’ll look for clinical signs like hair loss and skin lesions, which can indicate fungal infection but might also be caused by other skin conditions.
To confirm the diagnosis, several tests might be done: Using a Woods lamp, the vet checks if affected hairs fluoresce under UV light, suggesting ringworm. Fungal culture involves collecting samples from affected skin or hair; it’s the most reliable but can take up to 10 days.
Microscopy lets the vet inspect hair and skin samples for fungal elements quickly. PCR testing detects fungal DNA and offers a faster diagnosis in some cases.
Since symptoms overlap with other conditions such as mange or yeast infections, these diagnostic tools help verify accurate identification and proper treatment.
