Dog ringworm treatment

Treatments for Ringworm

Treatment typically involves antifungal shampoos, ointments, or oral medications. Since ringworm is contagious to pets and their humans, it's also important to handle an infected dog with care and clean the environment thoroughly to prevent the spread of the infection. This is how to treat ringworm on dogs:

Topical Therapy:

  • Medicated Shampoos and Ointments: Products containing miconazole, chlorhexidine, or ketoconazole are often recommended for treating ringworm. These antifungal shampoos and ointments help to kill the fungus on the skin and in the hair follicles. Regular bathing (about twice a week) with these medicated shampoos can reduce the spread of the fungus.
  • Lime Sulfur Dip: This is a very effective topical treatment for ringworm. Lime sulfur dips are usually recommended to be applied once or twice a week. They are known for their effectiveness, but they can have a strong odor and can temporarily discolor the coat of light-colored dogs.

Systemic (Oral) Antifungal Medication:

  • Itraconazole: This is one of the most commonly used oral antifungal medications for ringworm in dogs. It's generally well-tolerated and is effective against most strains of the fungi causing ringworm.
  • Terbinafine: Another effective oral antifungal medication, terbinafine is sometimes used, particularly if the dog does not tolerate itraconazole well.
  • Fluconazole: This is another option, often used when other medications aren't effective or can't be used.

Important Considerations:

Veterinary Guidance:

Always consult a veterinarian for a definitive diagnosis and treatment plan. Ringworm can mimic other skin conditions, and misdiagnosis can lead to ineffective treatment.

Duration of Treatment:

Treatment usually needs to continue for several weeks, and it's important to complete the full course of treatment as prescribed by a vet, even if the symptoms seem to have resolved.

Environmental Cleaning:

Ringworm can spread in the environment, so it's important to regularly clean and disinfect areas where the dog spends time. This includes bedding, grooming tools, and surfaces.

Ringworm is a zoonotic disease, meaning it can be transmitted from pets to humans, so it's important to handle infected animals with care and maintain good hygiene practices.
