02 Oct Ringworm in Dogs: Causes, Symptoms, and Treatment

Ringworm is a common fungal infection that can affect dogs. Despite its name, ringworm is not caused by worms, but rather by a group of fungi known as dermatophytes. These fungi can infect a dog’s skin, fur, and sometimes even their nails. In this blog post, we will explore the causes, symptoms, and treatment options for ringworms in dogs helping you better understand this condition and how to care for your furry friend.

Causes of Ringworms in Dogs

Ringworm in dogs is caused by a group of fungi known as dermatophytes. These fungi can infect a dog’s skin, fur, and sometimes even their nails. The primary causes of ringworms in dogs include:

1. Fungal Spores: Dermatophytes responsible for ringworm shed fungal spores that can survive in the environment for an extended period. When a dog comes into contact with these spores, they can become infected.
2. Direct Contact: The most common mode of transmission is direct contact with an infected animal. This can occur through play, grooming, or even when sharing bedding or other personal items.
3. Contaminated Objects: Ringworm spores can also be found on contaminated objects, such as brushes, combs, or bedding. If a dog uses or shares these items, they can become exposed to the fungus.
4. Environmental Factors: In some cases, dogs can contract ringworm from the environment itself. Dermatophytes can thrive in damp and warm areas, such as soil or decaying organic matter. If a dog has open wounds or scratches, they may pick up the fungus from contaminated soil.
5. Carrier Animals: Even asymptomatic carrier animals, those that carry the fungus without showing symptoms, can transmit ringworm to other animals. It’s crucial to be cautious around animals of unknown health status.
6. Weakened Immune System: Dogs with weakened immune systems, such as puppies, elderly dogs, or those with underlying health conditions, are more susceptible to ringworm infections. Their immune systems may struggle to combat the invading fungus effectively.
7. Stress: High levels of stress or a stressful environment can compromise a dog’s immune system, making them more vulnerable to ringworm and other infections.

Symptoms of Ringworms in Dogs

Ringworms in dogs can manifest with various symptoms, and their appearance may vary from one dog to another. It’s essential to be vigilant and recognize the signs of ringworm to seek prompt veterinary care and prevent its spread. Common symptoms of ringworm in dogs include:

1. Circular Patches: The hallmark symptom of ringworms in dogs is the development of circular, red, and scaly patches on the skin. These patches often have a raised, ring-like edge, giving the condition its name. The centre of these lesions may appear more normal or crusty.
2. Hair Loss: Affected areas usually lead to hair loss, causing bald patches or thinning of the fur. Hair loss may vary in severity, and it can be more pronounced at the edges of the circular lesions.
3. Dry, Flaky Skin: The skin around the affected area can become dry, crusty, or flaky. This may result in discomfort and itching for the dog.
4. Inflammation and Redness: Infected skin may appear inflamed and reddened, particularly around the circular patches. This inflammation can contribute to itching and discomfort.
5. Itching: Some dogs with ringworms may experience itching and scratching, while others may not exhibit any signs of discomfort. Itchiness can depend on the individual dog’s immune response to the infection.
6. Spread of Lesions: If left untreated, ringworms in dogs can spread to other areas of the body. It creates multiple circular lesions. Finally, this can make the condition more challenging to manage.
7. Nail Changes: In some cases, ringworms in dogs can affect the nails, causing them to become brittle, discoloured, or deformed. This is less common but can occur.

1. Itching: Some dogs may experience itching and discomfort, while others may not exhibit any signs of discomfort at all.

Diagnosis and Treatment

If you suspect your dog has ringworm, it’s crucial to consult a veterinarian for a proper diagnosis and treatment plan. The vet will perform tests, including a fungal culture and microscopic examination of hair and skin samples, to confirm the presence of ringworms in dogs.

Treatment options for ringworms in dogs may include:

1. Topical Antifungal Medications: These are usually applied directly to the affected area and are effective for mild cases.
2. Oral Antifungal Medications: For more severe or widespread infections, oral antifungal medications may be prescribed by the vet.
3. Environmental Cleaning: It’s essential to thoroughly clean and disinfect your dog’s living area, including bedding, grooming tools, and toys, to prevent reinfection.
4. Isolation: Infected dogs should be isolated from other animals to prevent the spread of the fungus.
5. Regular Check-ups: Follow-up visits to the vet are crucial to monitor your dog’s progress and ensure the infection has cleared.

Preventing Ringworm

Continuing from where we left off, let’s delve further into the preventive measures you can take to protect your beloved canine companion from ringworm:

4. Regular Vet Check-ups: Schedule regular veterinary check-ups for your dog. Routine examinations can help detect early signs of ringworms in dogs or other health issues before they become severe.
5. Vaccinations: Ensure that your dog’s vaccinations are up-to-date. While vaccines specifically for ringworm are not available, maintaining overall health can help your dog’s immune system fight off infections more effectively.
6. Proper Nutrition: Feed your dog a balanced and nutritious diet. A healthy diet supports a strong immune system, which can play a crucial role in preventing and recovering from ringworm infections.
7. Limit Exposure: If you’re aware of a ringworm outbreak in your local area or among other dogs your pet interacts with, take extra precautions. Avoid visits to places where infected dogs have been and limit contact with unfamiliar animals.
8. Fungal Shampoos: Consider using antifungal shampoos as a preventive measure, especially if your dog frequently interacts with other animals or spends time in environments where ringworm may be more prevalent.
9. Educate Yourself: Learn more about the signs and symptoms of ringworm in dogs so you can quickly recognize any potential issues. Early detection can lead to faster treatment and better outcomes.
10. Hand Hygiene: Practice good hand hygiene after handling your dog, especially if they have been in contact with other animals. Wash your hands thoroughly with soap and water to reduce the risk of transmitting the fungus to yourself or other pets.
11. Limit Stress: High levels of stress can weaken your dog’s immune system. It also makes them more susceptible to infections like ringworm. Therefore, ensure your pet’s environment is as stress-free as possible.

The Last Word

In conclusion, ringworm in dogs is a contagious fungal infection that can be effectively managed with prompt diagnosis and appropriate treatment. By following the preventive measures outlined in this article, you can significantly reduce the risk of your dog contracting ringworm. Remember that maintaining your dog’s overall health through proper nutrition, regular veterinary care and a clean living environment can play a vital role in keeping them ringworm-free.
