Medical conditions in dogs
What is Ringworm?
Despite its name, ringworm isn’t caused by a worm at all. It’s a fungal infection that affects the skin, hair, and nails. The name comes from the characteristic circular or ring-shaped rash it often produces.
Symptoms and signs
How can I tell if my dog has ringworm?
Recognising the signs of ringworm is important for early intervention. Look for:
- Circular or Ring-Shaped Lesions: These lesions often have a red, raised border and a clear center.
- Hair Loss: Patchy hair loss, often in circular patterns.
- Scaly or Crusty Skin: Dry, flaky, or crusty skin within the lesions.
- Itching: Although not always present, some dogs may experience itching.
- Lesions on the Head, Paws, or Ears: Ringworm often affects these areas.
Diagnosis
How can I tell if my dog has ringworm?
Your veterinarian will use a combination of methods to diagnose ringworm:
- Wood’s Lamp Examination: A special ultraviolet light that can make some ringworm fungi fluoresce (glow).
- Microscopic Examination: Examining hair or skin scrapings under a microscope to look for fungal spores.
- Fungal Culture: Growing a sample of hair or skin in a laboratory to identify the specific fungus.
Causes
What are the causes of ringworm in dogs?
Ringworm is caused by various types of fungi called dermatophytes. These fungi thrive in warm, humid environments and can be spread through:
- Direct Contact: Contact with an infected animal or person.
- Indirect Contact: Contact with contaminated objects, such as bedding, grooming tools, or soil.
- Spores: Ringworm fungi produce spores that can survive in the environment for a long time.
Treatment
What are the treatment options for ringworm in dogs?
Treatment for ringworm typically involves:
- Topical Medications: Antifungal creams, shampoos, or dips applied to the affected areas.
- Oral Medications: Antifungal medications given by mouth in more severe or widespread cases.
- Environmental Decontamination: Cleaning and disinfecting the environment to prevent re-infection. This may involve washing bedding, vacuuming, and using antifungal sprays.
- Clipping Hair: In some cases, clipping the hair around the lesions may be recommended to improve the effectiveness of topical medications.

Important considerations about ringworm
Contagiousness: Ringworm is contagious to other animals and humans. Take precautions to prevent spreading the infection.
Zoonotic Potential: Ringworm can be transmitted from animals to humans (zoonotic). Wash your hands thoroughly after handling your dog and seek medical attention if you develop any skin lesions.
Treatment Duration: Ringworm treatment can take several weeks or even months to be fully effective. It’s important to follow your veterinarian’s instructions carefully and complete the full course of treatment.
If you suspect your dog has ringworm, consult your veterinarian promptly. With proper diagnosis and treatment, ringworm can be effectively managed, and your dog can return to a healthy, comfortable state.
