Ringworm, despite its name, isn't caused by a worm at all. It's a highly contagious fungal infection, technically known as dermatophytosis, that affects the skin, hair, and sometimes nails of dogs (and humans!). Understanding what it looks like is crucial for early detection and treatment. This guide will help you identify ringworm in your canine companion.
What are the common signs of ringworm in dogs?
The appearance of ringworm can vary, making diagnosis sometimes tricky. Common signs include:
- Circular, Hairless Patches: This is the hallmark sign, giving the infection its name. These patches often have a raised, scaly border. The center might appear less inflamed than the edges. However, not all ringworm lesions are circular.
- Redness and Inflammation: The affected skin is often red and inflamed, sometimes appearing irritated or itchy. Your dog might lick or scratch the area excessively.
- Scaling and Crusting: The skin within the affected area may be flaky, scaly, or crusted.
- Hair Loss: This is a significant symptom, with patches of hair falling out within the circular lesions. The hair loss can vary in severity.
- Thickened Skin: In some cases, the affected skin becomes thickened.
How do I know if it's ringworm or something else?
Several skin conditions can mimic ringworm. It’s crucial to consult a veterinarian for a proper diagnosis. Conditions that can resemble ringworm include:
- Allergies: Allergic reactions can cause redness, itching, and hair loss.
- Mange: This parasitic infection can also cause hair loss and skin irritation, but it typically presents differently than ringworm.
- Bacterial Infections: Bacterial skin infections can produce similar symptoms.
Can ringworm spread to humans?
Yes, ringworm is zoonotic, meaning it can spread from animals to humans. Therefore, it's important to practice good hygiene and seek veterinary care immediately if you suspect your dog has ringworm. Good hygiene includes washing your hands thoroughly after handling your dog.
How is ringworm in dogs diagnosed?
Veterinarians use several methods to diagnose ringworm:
- Visual Examination: A physical examination is the first step. The vet will look for the characteristic lesions.
- Wood's Lamp Examination: A Wood's lamp emits ultraviolet light that can cause the fungal spores to fluoresce, making them easier to detect. However, this test isn't always conclusive.
- Microscopic Examination: A sample of skin scrapings or hair is examined under a microscope to identify fungal hyphae (the structures of the fungus).
- Culture: A sample is cultured in a lab to grow the fungus and confirm the diagnosis. This is the most definitive test.
What is the treatment for ringworm in dogs?
Treatment usually involves antifungal medications, either topical or oral, depending on the severity of the infection. Your veterinarian will determine the best course of action. In addition to medication, your vet might recommend:
- Cleaning the affected area: Regular cleaning with an appropriate antifungal shampoo can help manage the infection.
- Environmental sanitation: Thorough cleaning of the dog's bedding, living spaces, and grooming tools is vital to prevent reinfection and spread.
Is ringworm contagious between dogs?
Yes, ringworm is highly contagious among dogs and can easily spread through direct contact or contaminated surfaces.
How long does it take for ringworm to clear up in dogs?
The recovery time varies depending on the severity of the infection and the treatment used. It can take several weeks or even months for the infection to fully clear. Consistent treatment and adherence to your veterinarian's instructions are crucial for successful management.

If you suspect your dog has ringworm, consult your veterinarian immediately for a proper diagnosis and treatment plan. Early intervention is key to preventing the spread of this contagious fungal infection.
