It might surprise you to know that ringworm is not actually a worm at all, but a fungal infection. Common in all regions of the world, ringworm can infect almost any animal, including dogs, which is why dog owners should be aware of the signs, causes, symptoms, and treatment.


1. What is Ringworm Exactly?

Ringworm gets its confusing name from its raised, round, red ring appearance that can be clearly seen in human ringworm infections. Scientifically known as dermatophytes, ringworm in dogs is commonly caused by a fungus known as Microsporum Canis. This fungus lives and grows in the top layer of skin and also in the hair follicles. You might also find cases of ringworm that spread to the dog’s claws. The good news is that ringworm usually affects a few areas of the dog’s body rather than causing widespread infection. Senior dogs, puppies, and dogs with lower immunity may sometimes suffer from a more severe infection.
