Ringworm in Dogs

If you suspect your dog has ringworm, don’t panic. There are many treatment options available to clear up the infection once it’s diagnosed. While ringworm can spread from animal to human, it’s more common for humans to get ringworm from other humans and for animals to get it from other animals.

Ringworm is a contagious, superficial fungal infection of the hair, nails and upper layers of the skin.

Ringworm is not a worm, but is named after the circular pattern of the infection. The fungus that causes ringworm lives on skin or in hair and can be spread through contact with spores or microscopic fungus particles. Ringworm manifests as bald patches on your dog’s fur; if you think your dog may have this condition consult with your vet immediately.

Ringworm manifests as bald patches on your dog’s fur, which is why it’s named ringworm.

Ringworm is a fungal infection of the skin that manifests as bald patches on your dog’s fur. It’s named for its circular shape, which resembles a ring. In fact, it’s not worm at all—it’s a fungus that grows on the skin and can be spread from animal to animal by physical contact or from an infected animal to humans by touch or contact with infected objects (like grooming tools).

Ringworm is spread through contact with spores or microscopic fungus particles. Spores are the reproductive part of a fungus that can survive in dead wood, soil and animal hair for years. If a person touches an infected area on an animal, they can easily become infected by touching their own skin. The spores spread when you touch anything contaminated by the animal’s skin, including furniture and bedding.

Ringworm is a fungal infection of the skin, hair, or nails that’s caused by microscopic fungi known as dermatophytes. You can contract ringworm from an infected person’s skin (or any other surface they touch). It’s also possible to get it when you inhale spores or microscopic fungus particles (like when an infected dog licks you) or when you touch your eyes after petting a pet with ringworm. The ringworm fungus lives on dead skin cells and thrives in warm moist areas of the body like armpits and groins.

If you suspect ringworm on your dog, take him to your vet right away.

If you suspect ringworm on your dog, take him to your vet right away. The sooner you can get treatment for the infection, the less likely it is that it will spread to other pets or people in your home. Ringworm may not be a serious disease but it can be contagious, so prevention is important.

Your veterinarian will do a Wood’s lamp test to diagnose ringworm. The Wood’s lamp is an ultraviolet (UV) light that can help identify ringworm because it causes a red or orange fluorescence on the skin when it comes in contact with the fungus. However, this method is not always used to diagnose ringworm since some infected dogs don’t exhibit this characteristic glow.

Your vet will also culture your pet’s skin samples to confirm the presence of the fungus. Samples are taken from an affected area and grown in a culture dish for several days. The fungus is identified under a microscope by its shape and size, or with staining techniques that highlight certain features (e.g., color).
