Ringworm in Dogs: Symptoms, Treatment, and Prevention
September 20, 2023
Ringworm is a common fungal infection that can affect dogs of all breeds and ages. Despite its name, ringworm has nothing to do with worms; rather, it's a skin condition caused by various fungal species. This article will explore ringworm in dogs, its symptoms, causes, treatment options, and ways to prevent its spread.
Understanding Ringworm in Dogs
Ringworm in dogs, also known as dermatophytosis, is a contagious fungal infection that primarily affects a dog's skin, hair, and, occasionally, nails. It is zoonotic, which means it can be transmitted from dogs to humans and vice versa. The three most common fungal species that cause ringworm in dogs are Microsporum canis, Microsporum gypseum, and Trichophyton mentagrophytes. (1)
What Causes Ringworm in Dogs?
Ringworm is highly contagious and can spread through direct contact with an infected dog or indirectly through contaminated objects and environments. Some common sources of infection include:
-
Infected animals: Contact with other infected dogs, cats, or even rodents can transmit the fungus.
- Contaminated objects: Items like grooming tools, bedding, toys, or even shared crates can harbor the fungus.
- Environment: Fungal spores can survive in the environment for an extended period, making places like dog parks, shelters, and boarding facilities potential sources of infection.
Symptoms of Ringworm in Dogs
Identifying ringworm in dogs can be challenging as the symptoms can vary and may resemble other skin conditions. Some common signs to watch for include:
- Circular Skin Lesions: These are the hallmark of ringworm in dogs. They often appear as raised, red, and scaly circles with a clear or slightly raised center.
- Hair Loss: Hair loss around the affected area is a common symptom, making the lesion more noticeable.
- Itching and Irritation: Dogs with ringworm may scratch or chew at the affected areas due to discomfort.
- Crusty or Flaky Skin: The skin around the lesions may become crusty or flaky.
- Brittle or Broken Nails: In some cases, ringworm can affect a dog's nails, causing them to become brittle or break easily.
- Swelling and Redness: The affected area may be swollen and appear red and inflamed.
- Spread of Lesions: Without treatment, the lesions can spread to other parts of the body.
It's essential to consult a veterinarian if you suspect your dog has ringworm or exhibits any of these symptoms.
Untreated Ringworm in Dogs
If left untreated, ringworm in dogs can worsen and potentially lead to more severe complications. These may include:
- Secondary Infections: Scratching and biting at the affected areas can introduce bacterial infections.
- Chronic Infection: Untreated ringworm can become chronic, making it more challenging to eradicate.
- Transmission to Humans: Dogs can transmit the fungus to their owners or other pets in the household. (2)
Treatment for Ringworm in Dogs
Treating ringworm in dogs typically involves a combination of medical intervention and hygiene measures. Here are the primary treatment options:
- Topical Antifungal Medications: Your veterinarian may prescribe antifungal creams, shampoos, or ointments to apply directly to the affected areas. Be sure to follow the vet's instructions carefully.
- Oral Antifungal Medications: In more severe cases, oral antifungal medications may be necessary. These are typically prescribed for several weeks to ensure the infection is fully eradicated.
- Environmental Decontamination: Cleaning and disinfecting your dog's environment is crucial to prevent reinfection. Wash bedding, toys, and grooming tools regularly.
- Isolation: Infected dogs should be isolated from other pets to prevent the spread of the fungus.
- Regular Veterinary Check-ups: Regular follow-up visits to the veterinarian are essential to monitor your dog's progress and ensure the infection is clearing up.
How to Treat Ringworm in Dogs at Home
While it's crucial to consult a veterinarian for proper diagnosis and treatment, there are some additional steps you can take at home to support your dog's recovery:
- Maintain Good Hygiene: Wash your hands thoroughly after handling your dog, especially if you suspect they have ringworm.
- Isolate Infected Dogs: Keep infected dogs away from other pets in the household.
- Clean and Disinfect: Regularly clean and disinfect your home, focusing on areas your dog frequents.
- Antifungal Shampoos and Ointments: Your veterinarian may recommend specific antifungal shampoos or ointments that can be used at home as part of the treatment regimen. Follow your vet's instructions carefully when applying these products. These topical treatments can help kill the fungus and relieve itching and discomfort.
- Boost Immunity: A healthy diet and regular exercise can help boost your dog's immune system, aiding in recovery. Ensure your dog is getting a balanced diet with essential nutrients that support skin and coat health. Consult with your vet to determine if any dietary supplements may be beneficial.

What Does Ringworm Look Like in Dogs?
