Ringworm is not, as the name suggests, a disease caused by a worm. It is instead a fungal infection of the skin, also known as "dermatophytosis."

Ringworm is contagious and very easily passed from one individual to another. Many species of animals are susceptible to ringworm, including both dogs and cats. Humans are also susceptible to ringworm, and you can become infected from an infected pet or from another infected person.

How Can a Dog or Cat Get Ringworm?

Ringworm can be passed to your dog or cat by contact with another animal or a person who is infected with ringworm. He can also be infected by exposure to contaminated objects, such as grooming utensils, bedding, ​and dishes. They can also be infected by fungal spores found in the soil.

Ringworm occurs more commonly in cats than in dogs, though both species can be affected. Puppies and kittens have an increased risk of infection compared to adults. Yorkshire Terriers, hunting and working dog breeds, and Persian cats appear to be predisposed to the disease.

How Can a Person Get Ringworm?

People can become infected with ringworm through contact with infected pets. However, they can also become infected through contact with other infected people and through contact with contaminated objects and surfaces.

How Can You Protect Yourself From Ringworm?

If you believe your pet has ringworm, you should visit your veterinarian as soon as possible. All animals in the household may need to be treated. Even pets that are not showing signs may have been exposed to the disease.

Ringworm spores are very hard to kill and can survive for over a year in a contaminated environment. It is important to get rid of the spores when treating ringworm for your dog or cat.

  • Wash your hands thoroughly after handling your pet. Traumatized skin (open wounds and abrasions) is more susceptible to ringworm, so keep these areas clean and covered.
  • Wash your pet's bedding, toys, grooming utensils, dishes and other paraphernalia with a disinfectant that kills ringworm spores.
  • Any pet supplies that cannot be disinfected should be discarded.
  • Vacuum your flooring regularly to remove loose hair. The spores can survive on these hairs.
  • If possible, keep infected animals isolated in an easy to clean and disinfect area.

Remember, you can get ringworm from people as well. Avoid sharing clothing, towels, or other items with any individual that has ringworm. Wear sandals or slippers when in public locker rooms or shower areas.

If you suspect your pet is sick, call your vet immediately. For health-related questions, always consult your veterinarian, as they have examined your pet, know the pet's health history, and can make the best recommendations for your pet.
