My Dog Has Ringworm: The Symptoms You Have to Watch Out For
Ringworm. The name itself can conjure images of creeping, circular rashes and uneasy scratching. While the name might suggest worms, ringworm is actually a highly contagious fungal infection that can affect both humans and animals, including your beloved canine companion. If you suspect your dog might have ringworm, it’s crucial to be informed. This article will guide you through the symptoms to watch out for, helping you identify the issue early and seek appropriate veterinary care.
What is Ringworm in Dogs?
Ringworm, scientifically known as dermatophytosis, is caused by a group of fungi that thrive on keratin, the protein that makes up hair, skin, and nails. These fungi infect the outermost layers, leading to the characteristic lesions. While it’s not a life-threatening condition, ringworm is extremely itchy and uncomfortable for your dog, and it can spread easily to other pets and even to you and your family. Early detection and treatment are key to preventing the spread and ensuring your dog’s comfort.
Common Symptoms of Ringworm in Dogs
Recognizing the signs of ringworm is the first step in getting your dog the help they need. Here are the most common symptoms to look out for:
- Circular or Patchy Hair Loss: This is the hallmark symptom. You might notice small, circular patches of hair loss, often on the face, ears, paws, or limbs. The skin within these patches may appear red, inflamed, or scaly.
- Scaly Skin: The affected skin can become dry, flaky, and scaly. This scaling is often accompanied by redness and irritation.
- Itching (Pruritus): Ringworm is incredibly itchy. Your dog might scratch, lick, or chew at the affected areas, potentially worsening the infection and spreading it.
- Crusting: In some cases, crusts may form on the skin, particularly around the edges of the lesions.
- Brittle or Broken Hairs: The fungus weakens the hair shafts, causing them to break easily. You might notice hairs that are stubbly or appear broken off near the skin.
- Inflammation: The skin around the affected areas can become inflamed, appearing red and irritated.
- Nail Infections: In rare cases, ringworm can also affect the nails, causing them to become thick, misshapen, and brittle.
Important Note: The severity of these symptoms can vary depending on the dog’s immune system, the type of fungus involved, and the extent of the infection.
Diagnosis and Treatment of Ringworm in Dogs
If you observe any of these symptoms, it’s essential to consult your veterinarian immediately. They will conduct a thorough examination and may use several methods to diagnose ringworm:
- Physical Examination: The vet will visually assess your dog’s skin and coat.
- Wood’s Lamp Examination: A Wood’s lamp emits ultraviolet light. Some ringworm fungi fluoresce (glow) under this light, making them easier to spot. However, not all ringworm strains fluoresce.
- Fungal Culture: This is the most reliable diagnostic method. A sample of hair and skin is taken and cultured in a lab to identify the specific fungus. This may take several weeks to produce results.
- Microscopic Examination: Your vet might examine hair samples under a microscope to look for fungal spores.
Treatment typically involves a combination of approaches:
- Topical Medications: Antifungal creams, ointments, or shampoos are often prescribed to treat localized infections.
- Oral Medications: In more severe cases or when multiple areas are affected, your vet may prescribe oral antifungal medications.
- Environmental Control: Cleaning and disinfecting your dog’s environment, including bedding, grooming tools, and areas where your dog spends time, is crucial to prevent the spread of the infection and reinfection.
- Isolation: If possible, isolate your infected dog from other pets and people to prevent the spread of the fungus.
- Grooming: Regular grooming, using a brush that can be disinfected, can help remove loose hairs and spores, preventing further spread.
Preventing the Spread of Ringworm
Ringworm is highly contagious. Here are some steps you can take to minimize the risk of transmission:
- Practice Good Hygiene: Wash your hands thoroughly after handling your dog or any potentially contaminated items.
- Clean and Disinfect: Regularly clean and disinfect your home, paying particular attention to surfaces your dog frequents.
- Avoid Sharing: Do not share grooming tools, bedding, or toys with other pets.
- Monitor Other Pets: Keep a close eye on any other pets in your household and watch for signs of ringworm.
- Consult Your Vet: If you suspect ringworm, do not delay seeking professional veterinary advice.
Conclusion
Ringworm can be an unpleasant experience for your dog, but with prompt diagnosis and treatment, it’s manageable. By being vigilant for the telltale symptoms and taking preventative measures, you can protect your dog, other pets, and yourself from this contagious fungal infection. Remember to consult your veterinarian immediately if you suspect your dog has ringworm.

1. Can humans get ringworm from dogs?
Yes, ringworm is zoonotic, meaning it can be transmitted between animals and humans. You can contract ringworm through direct contact with an infected dog or by touching contaminated surfaces.
2. How long does ringworm last in dogs?
The duration of ringworm depends on the severity of the infection and the treatment provided. With proper treatment, ringworm can often resolve within a few weeks to a couple of months.
3. Is ringworm contagious to cats?
Yes, ringworm is highly contagious to cats, as well as other animals. If you have multiple pets, it’s essential to isolate the infected pet and take precautions to prevent the spread.
4. Can ringworm go away on its own?
While it’s possible for ringworm to resolve on its own, it’s unlikely and can take a very long time. Treatment is recommended to speed up recovery and prevent the spread of the infection.
5. Is ringworm dangerous for my dog?
Ringworm itself is not typically life-threatening. However, the itching and discomfort can be significant, and secondary bacterial infections can occur if the dog scratches excessively. Early treatment is crucial to minimize these risks.
