Canine Ringworm Infections

Canine ringworm is the name of an infection caused by fungus and is not related to worms at all. Ringworm is contagious and can be spread to humans and other pets.

Facts

The ringworm fungus is spread through animal-to-animal contact or animal-to-infected-item contact. This can include grooming supplies, bedding or kennel areas. Ringworm spores can live without a host for up to 18 months.

Types

There are several types of ringworm common in canines, including Trichophyton mentagrophytes, Microsporum canis and Microsporum gypseum. The fungus type does not influence symptoms or treatment.

Symptoms

The fungus causes the dog's hair to fall out in circular or semicircular patches near its head, tail or paws. This is often the first sign of a ringworm problem. In addition, the dog may have red, itchy or scaly skin.

Identification

A veterinarian will perform a physical examination to evaluate the dog's hair follicles. The skin may be viewed under an ultraviolet light, and hair samples may be taken for laboratory tests.

Treatment

Canine ringworm is treated with anti-fungal shampoos, salves applied directly to the skin or an oral anti-fungal. The infected area may be shaved to prevent the spread of the fungus.
