Understanding Ringworm in Dogs
Ringworm, also known as dermatophytosis, is a common fungal infection that can affect dogs. It is important for dog owners to have a good understanding of the causes and transmission of ringworm in dogs to ensure early detection and appropriate treatment.
Causes of Ringworm in Dogs
Ringworm in dogs is caused by different types of fungi, with the majority of cases (about 70%) caused by Microsporum canis, 20% by Microsporum gypseum, and 10% by Trichophyton mentagrophytes (Merck Veterinary Manual). These fungi are present in the environment and can infect dogs when they come into contact with them.
Certain factors can increase the risk of ringworm infection in dogs, such as a weakened immune system, young age, or living in crowded or unsanitary conditions. Yorkshire Terriers may be more susceptible to persistent and widespread infections (Merck Veterinary Manual).
Transmission of Ringworm in Dogs
Ringworm in dogs is highly contagious and can be transmitted through various means. The primary mode of transmission is direct contact with infected animals, such as during playing, grooming, or mating. Additionally, ringworm can spread through contact with contaminated objects, including furniture, grooming tools, bedding, or even household surfaces (Merck Veterinary Manual).
The spores responsible for the spread of ringworm can survive in the environment for an extended period, up to 18 months, making it important to thoroughly clean and disinfect areas where an infected dog has been (American Kennel Club). It’s worth noting that humans can also catch ringworm from infected dogs, as it is a zoonotic infection. Proper hygiene practices and prompt treatment are crucial to prevent the spread of ringworm between animals and humans (GoodRx).

Early detection and treatment are key to managing ringworm effectively and ensuring the well-being of both the infected dog and other animals or people in contact with the dog.
Symptoms of Ringworm in Dogs
When it comes to identifying ringworm in dogs, it’s important to be aware of the common symptoms that may indicate an infection. Ringworm in dogs is characterized by specific skin changes and hair loss. Here are the two primary symptoms to look out for:
Skin Lesions and Hair Loss
Ringworm typically presents as circular areas of hair loss throughout the body. These lesions may start small and gradually enlarge over time. The affected areas may have a red, inflamed appearance, and in some cases, scabs may develop. As the lesions progress, they may begin to heal in the center while still expanding at the edges, giving them a characteristic ring-like appearance. It’s important to note that not all ringworm lesions exhibit the classic ring shape, and some may have a more irregular appearance.
Commonly Affected Areas
In dogs, ringworm tends to affect specific areas of the body. The face, ears, tail, and feet are commonly affected due to a higher concentration of hair and moisture in these areas. The fungus responsible for ringworm thrives in warm and humid environments, making these regions more susceptible to infection.
In addition to hair loss and skin lesions, other symptoms may include:
- Dry, scaly skin
- Inflamed areas of skin
- Darkened patches of skin
- Itchiness and scratching
- Excessive grooming
- Inflamed nail beds
- Darkened or dry nails
- Dry, brittle, or misshapen nails
It’s important to note that these symptoms can vary in severity and may not always be present in every case of ringworm in dogs. If you suspect that your dog may have ringworm, it’s crucial to consult with a veterinarian for an accurate diagnosis and appropriate treatment.

By recognizing the symptoms of ringworm in dogs and seeking timely veterinary care, you can effectively protect your furry friend and prevent the spread of this contagious fungal infection.
Diagnosing Ringworm in Dogs
When it comes to ringworm in dogs, accurate diagnosis is essential for effective treatment. There are several methods used by veterinarians to diagnose ringworm in dogs, including fungal culture examination and ultraviolet (UV) lamp examination.
Fungal Culture Examination
Fungal culture examination is considered the most accurate method for diagnosing ringworm in dogs. This involves taking samples of hair and skin scrapings from the affected areas and sending them to a laboratory for analysis. The samples are placed in a culture medium that promotes the growth of fungal organisms (Merck Veterinary Manual).
The laboratory then observes the samples over a period of time, typically one to three weeks, to see if any fungal spores grow. A positive culture confirms the presence of ringworm. This method allows for the identification of the specific fungus causing the infection, which helps determine the most appropriate treatment plan.
Ultraviolet Lamp Examination
Another method used to diagnose ringworm in dogs is the ultraviolet (UV) lamp examination, also known as a Wood’s lamp examination. In this procedure, a handheld UV lamp is used to shine ultraviolet light on the affected areas of the dog’s skin. Certain types of ringworm fungi will fluoresce under the UV light, appearing as a greenish glow (PetMD).
While the UV lamp examination can be a useful tool to aid in the diagnosis of ringworm, it is important to note that not all types of ringworm fungi fluoresce under the UV light. Therefore, a negative result does not definitively rule out ringworm. Additional diagnostic methods, such as fungal culture examination, may be necessary for a conclusive diagnosis.
It’s important to consult with a veterinarian if you suspect your dog has ringworm. They will be able to perform the necessary diagnostic tests to confirm the presence of ringworm and develop an appropriate treatment plan.

By accurately diagnosing ringworm in dogs, veterinarians can provide the appropriate treatment to help your furry friend recover from this fungal infection. Remember, prompt diagnosis and treatment not only alleviate your dog’s discomfort but also help prevent the spread of ringworm to other pets and humans in the household.
Treating Ringworm in Dogs
When it comes to treating ringworm in dogs, a comprehensive approach is essential to eliminate the fungal infection and prevent its spread. Treatment usually involves a combination of medicated shampoos and dips, as well as oral medications. Let’s explore these treatment options in more detail.
Medicated Shampoos and Dips
Medicated shampoos and dips are commonly used to treat the entire coat of dogs infected with ringworm. These topical treatments contain antifungal agents that help eliminate the fungal infection. The active ingredients in these products can include miconazole, chlorhexidine, or lime sulfur.
To effectively use medicated shampoos or dips, it’s important to follow the instructions provided by your veterinarian. Generally, you’ll need to thoroughly wet your dog’s coat and apply the shampoo or dip, making sure to work it into a lather and cover all affected areas. Leave the product on for the recommended amount of time before rinsing it off. Repeat the treatment as directed by your veterinarian.
In addition to medicated shampoos and dips, your veterinarian may recommend other topical treatments such as antifungal creams or ointments for localized lesions. It’s crucial to follow your veterinarian’s instructions and complete the full course of treatment to ensure effective eradication of the infection.
Oral Medications
In more severe or long-term cases of ringworm, oral medications may be prescribed by your veterinarian. These medications, such as itraconazole or terbinafine, work systemically to eliminate the fungal infection from within the body.
Oral medications are typically reserved for cases that are more difficult to treat or when the infection has spread extensively. The duration of oral medication treatment can vary, ranging from several weeks to months. It’s important to strictly adhere to the prescribed dosage and duration, as stopping treatment prematurely can lead to a recurrence of the infection.
Your veterinarian will assess your dog’s condition and determine the most appropriate oral medication, dosage, and treatment duration based on the severity of the infection and your dog’s overall health.
It’s worth mentioning that treatment for ringworm in dogs requires a multi-faceted approach. In addition to medicated shampoos, dips, and oral medications, environmental decontamination is crucial to prevent reinfection. Cleaning and disinfecting your dog’s bedding, grooming tools, and living areas with a diluted bleach solution can help eliminate any remaining fungal spores (Merck Veterinary Manual).
