Ringworm in Dogs

ADVERTISEMENT

Treatment

 

Most dogs can be treated on an outpatient basis, but quarantine procedures should be considered due to the infective and zoonotic (transmittable to humans) nature of some types of dermatophytosis. If your veterinarian needs to prescribe antifungal medications, the use of an Elizabethan collar (a wide collar placed around the neck) is recommended to prevent ingestion of antifungal medications applied to the dog's skin.

 

Living and Management

 

A fungal culture is the only means of truly monitoring your dog's response to treatment. Many animals will improve clinically, but remain fungal culture positive. It is advisable to repeat fungal cultures toward the end of treatment, and continue treatment until at least one culture result is negative. In resistant cases, fungal cultures may be repeated on a weekly basis, and treatment continued until two to three consecutive negative results are obtained. Complete blood counts should be performed weekly or biweekly for animals receiving griseofulvin, an anti-fungous antibiotic. Also, blood work to monitor the liver may be indicated for dogs receiving ketoconazole or itraconazole, two types of anti-fungal medications.

 

Prevention

 

To prevent reinfection from other animals, the use of a quarantine period, and fungal (dermatophyte) cultures of all animals living in the household are necessary. Treatment of exposed animals should be considered to prevent repeated development of infection. The possibility of rodents aiding in the spread of the disease should be considered. If you suspect that your dog has access to rodents, or that rodents are in your immediate environment, it is highly advised that you take the necessary steps to eliminate the pests.
