Ringworm in dogs can also be transmitted by humans who are carrying the fungi on their skin or nails.

What are the symptoms of ringworm in dogs?

The most common symptoms of ringworm in dogs include:

  • Circular, scaly, and red-shaped rash on the skin

How is ringworm in dogs diagnosed?

If you suspect your dog has ringworm, take them to a vet immediately. The vet will examine your dog’s skin and coat for signs of ringworm infection. The vet may use a UV light test to check for the presence of fungus on the skin. A skin sample may also be taken and examined under a microscope to confirm the diagnosis.
