What Are the Causes of Ringworm in Dogs?
Several species of fungi are the cause of ringworm in dogs. It most often occurs in fall and winter, and tends to affect younger dogs. Healthy adult dogs often have resistance to ringworm.

Spores
-
Fungus spores cause ringworm. These spores can live--and spread ringworm--for over 18 months.
Cats, Dogs and People
-
Ringworm is very contagious. It can spread from cats to dogs to people and back again. Children are more susceptible, but ringworm can affect adults as well.
-
Environment
-
Floors and living areas of infected animals can harbor ringworm spores. Areas should be disinfected with a bleach solution or disinfectant spray.
Clippers and Grooming Tools
-
Ringworm spores can live on grooming tools. The fungus can spread more easily to broken skin, so clippers are a primary source of infection if they are not disinfected.
Dust
-
Ringworm spores are microscopic and can be found in common household dust. An electrostatic duster is good for safely managing contaminated dust.
Pet Hair
-
Ringworm infects the hair follicle, so the fur and dander left by infected animals can spread the fungus. Wash bedding in hot water and bleach to kill spores.
Compromised Immune Systems
-
Dogs who are ill, treated with steroids or suffering from a compromised immune system are more susceptible to ringworm. Be cautious when boarding or grooming these dogs.
