Understanding Ringworm in Dogs
Ringworm is a common fungal infection that can affect dogs of all ages and breeds. It is important for dog owners to have a good understanding of this condition in order to provide appropriate care and treatment for their furry companions.
What is Ringworm?
Ringworm, despite its name, is not caused by a worm. It is actually a fungal infection that affects the skin, hair, and occasionally the nails of dogs. The term “ringworm” refers to the characteristic circular lesions that often appear on the affected areas of the skin (Moriello, Karen A.).
The fungi responsible for ringworm in dogs belong to a group called dermatophytes, with the most common species being Microsporum canis and Trichophyton mentagrophytes. These fungi thrive in warm, humid environments, making dogs more susceptible to infection, especially in crowded or stressful conditions. It is worth noting that ringworm can also be transmitted from dogs to humans, so proper precautions should be taken to prevent its spread.
Causes of Ringworm in Dogs
Ringworm in dogs is typically transmitted through direct contact with infected animals or contaminated objects, such as bedding, brushes, or grooming tools. The fungi can survive in the environment for extended periods, making it easy for dogs to come into contact with the infectious spores (Moriello, Karen A.). Factors that can contribute to the development of ringworm in dogs include:
- Weakened immune system: Dogs with compromised immune systems are more susceptible to fungal infections, including ringworm. This can occur due to underlying health conditions or certain medications.
- Stress: Stress weakens the immune system, making dogs more vulnerable to infections, including ringworm. Stressful situations, such as overcrowding in shelters, can increase the risk of ringworm transmission among dogs.
It’s important to note that some dog breeds, such as Terriers and Bulldogs, may be more prone to ringworm due to certain genetic factors. Additionally, young puppies have less developed immune systems and are more susceptible to ringworm infection (Moriello, Karen A.).
By understanding the nature of ringworm and its causes, dog owners can take appropriate measures to prevent and treat this fungal infection. Early detection and prompt treatment are crucial in managing ringworm in dogs. For more information on symptoms, diagnosis, and treatment options, continue reading our article on ringworm in dogs.
Symptoms of Ringworm in Dogs
Ringworm is a common fungal infection that can affect dogs. Identifying the symptoms of ringworm is crucial for early detection and effective treatment. The symptoms can manifest in visible signs on the skin as well as behavioral changes in your furry companion.
Visible Signs
One of the most recognizable signs of ringworm in dogs is the appearance of circular or irregularly-shaped patches on the skin. These patches may be scaly, red, or inflamed and often have a raised border. Hair loss is common within these patches, giving them a distinct appearance. It’s important to note that the name “ringworm” can be misleading, as the condition is not caused by worms but rather by a fungal infection.
The affected areas can be found anywhere on the dog’s body, including the head, ears, paws, and tail. Dogs with long or dense fur may have more difficulty noticing these visible signs, making regular grooming and inspection essential. If you suspect ringworm, it can be helpful to refer to ringworm in dogs pictures for visual reference.
Behavioral Changes
In addition to visible signs, ringworm in dogs can also cause behavioral changes. Affected dogs may exhibit increased itchiness or discomfort, leading to excessive scratching, licking, or chewing of the affected areas. This can further exacerbate the condition and potentially introduce secondary bacterial infections. If you notice your dog displaying unusual scratching behavior or paying excessive attention to specific areas of their body, it’s important to investigate further.
It’s worth noting that not all dogs infected with ringworm will display obvious symptoms. Some dogs may be asymptomatic carriers, meaning they can transmit the infection to other animals or humans without showing any signs themselves. Regular veterinary check-ups and screenings can help identify these carriers and prevent the spread of ringworm.
If you suspect your dog may have ringworm based on the visible signs or behavioral changes described above, it is important to consult with your veterinarian for a proper diagnosis. They can perform a thorough examination and conduct diagnostic tests, as discussed in the next section, to confirm the presence of ringworm and develop an appropriate treatment plan.
Understanding and recognizing the symptoms of ringworm in dogs is the first step toward effective treatment. Early detection and intervention can help prevent the spread of infection and provide your furry friend with the necessary care they need.

Diagnosing Ringworm in Dogs
When it comes to diagnosing ringworm in dogs, a veterinary examination along with specific diagnostic tests is essential to confirm the presence of this fungal infection.
Veterinary Examination
During a veterinary examination, the veterinarian will closely examine your dog’s skin and fur for visible signs of ringworm. They will look for characteristic circular lesions, hair loss, redness, and inflammation. The presence of these symptoms, along with a history of exposure to ringworm or contact with infected animals, can strongly indicate ringworm in dogs.
Additionally, the veterinarian may use a Wood’s lamp, also known as a blacklight, to examine your dog’s skin. Some strains of ringworm will fluoresce under ultraviolet light, which can aid in the diagnosis. However, it’s important to note that not all strains of ringworm will fluoresce, so a negative result from the Wood’s lamp doesn’t rule out the possibility of ringworm.
Diagnostic Tests
To confirm the diagnosis and determine the specific fungal species causing the infection, the veterinarian may recommend the following diagnostic tests:
-
Fungal Culture: A fungal culture involves taking a sample of hair or skin cells from the affected areas and placing them on a culture medium. The sample is then observed for fungal growth over a certain period of time. This test helps identify the specific fungal species responsible for the infection and allows for targeted treatment.
-
Microscopic Examination: The veterinarian may perform a microscopic examination of the hair and skin samples. This involves staining the samples and examining them under a microscope for the presence of fungal elements, such as spores or hyphae. Microscopic examination can provide initial evidence of ringworm, but it is often used in conjunction with other diagnostic tests for confirmation (Scott).
-
PCR Test: Polymerase Chain Reaction (PCR) testing is a molecular technique that can rapidly detect and identify the DNA of the fungal species causing the infection. PCR tests are highly sensitive and specific, providing accurate results for diagnosis (Moriello).
These diagnostic tests help veterinarians confirm the presence of ringworm and determine the most appropriate treatment plan for your dog. It’s important to consult with a veterinarian for an accurate diagnosis and to discuss the best course of action to manage and treat ringworm in your furry friend.

Treatment Options for Ringworm in Dogs
When it comes to treating ringworm in dogs, there are several options available. The choice of treatment depends on the severity of the infection and the recommendation of a veterinarian. Two common treatment options for ringworm in dogs are medications and topical treatments.
Medications
Medications are often prescribed by veterinarians to treat ringworm in dogs. These medications may include oral antifungal drugs, such as griseofulvin or itraconazole, which help to eliminate the fungal infection from within the body (Moriello, 2015). The dosage and duration of treatment will vary depending on the individual dog and the severity of the infection.
It’s important to note that some antifungal medications may have potential side effects, and they should only be administered under the guidance of a veterinarian. Regular monitoring of the dog’s health, including liver function, may be necessary during the course of treatment (Scott & Miller, 2012).
Topical Treatments
Topical treatments are another effective option for treating ringworm in dogs. These treatments involve applying antifungal creams, ointments, or shampoos directly to the affected areas of the dog’s skin (Moriello, 2015). Topical treatments help to target and eliminate the fungal infection externally.
Common topical treatments for ringworm in dogs may contain antifungal ingredients such as miconazole or clotrimazole. These products should be applied according to the instructions provided by the veterinarian or the product label. Regular bathing or washing of the dog’s skin with medicated shampoos can also aid in the treatment process.
Combining medications and topical treatments may be necessary for severe cases of ringworm. It’s important to follow the veterinarian’s instructions and complete the full course of treatment to ensure the complete eradication of the fungal infection.
