How to Treat Ringworm on a Dog's Tail

Dog tail ringworm may be caused by a moist environment, parasites, or nutritional deficiencies that lead to low skin resistance. Ringworm is a fungal (common in dogs) infection, and most cases are mixed bacterial and fungal infections. The treatment for fungal infections requires patience and persistence, as the cycle is long.

If your dog has ringworm on its tail, it is likely a fungal infection. Treatment involves oral antifungal drugs, along with topical antifungal sprays or medicated bath shampoos. Clinical symptoms of ringworm include moderate to severe itching, accompanied by regional or generalized hair loss, epidermal detachment, redness, and seborrhea. Ringworm spreads quickly, is moderately contagious, and has a long treatment cycle, with a high risk of recurrence.

Here's how to treat dog tail ringworm:

Before treatment, shave the affected area of the dog's tail, and clean the scales and secretions with physiological saline and cotton swabs. Spray the infected area with an antifungal medication containing components such as terbinafine and ketoconazole. Ensure that your dog wears an Elizabethan collar to prevent it from licking the medication.
Orally administer伊曲康唑或特比萘芬according to the dog's weight every 24 hours, lasting for 2 to 4 weeks. You can also combine anti-inflammatory drugs.
Use a medicated shampoo containing one of the following ingredients to bath the affected tail area and the whole body: 2% ketoconazole, 1% ketoconazole, 2% chlorhexidine, 2% miconazole, 2% to 4% chlorhexidine, or 1% selenium sulfide (for dogs), washing every 2 to 3 days. Shampoos containing two active ingredients are more effective. Continue using it until the lesions disappear.

The treatment cycle for fungal infections is long, so be patient. It may take about 4 weeks for the infection to improve. If there is no improvement after 1 to 2 weeks, consult a veterinarian for further skin disease checks, such as skin cytology tests, scrapings, pressing, staining, fungal cultures, etc., to confirm the specific cause and treat accordingly.
