Noticing itchy spots on your dog’s skin? Wondering if it might be ringworm? Despite its name, ringworm isn’t caused by worms at all—it's a common fungal infection that can affect your dog’s skin, fur, and nails. The good news? It’s treatable with the right care. Let’s dive into the symptoms, causes, and treatment options so you can help your furry friend feel better fast.

⚠️ What to Watch For

Ringworm in dogs can look different depending on the severity of the infection and your dog’s coat type. Knowing the key signs can help you catch it early and prevent it from spreading to other pets—or even to humans.

  • Circular patches of hair loss, often with scaly or crusty skin
  • Red, inflamed, or irritated skin
  • Excessive scratching or licking at affected areas
  • Brittle, discolored nails if the fungus affects the nail bed
  • Dandruff-like flakes on the coat

Keep in mind that some dogs may show mild or no symptoms at all, making it tricky to detect. If you suspect ringworm, it’s always best to consult a vet for a proper diagnosis.

🔍 Possible Causes

Ringworm is caused by a group of fungi called dermatophytes. These fungi thrive in warm, humid environments and can spread through direct or indirect contact. Here are some common ways dogs can pick up ringworm:

  • Contact with an infected animal (dog, cat, or other pets)
  • Exposure to contaminated objects like bedding, grooming tools, or toys
  • Spending time in damp or crowded spaces, such as dog parks or kennels

Puppies, senior dogs, and those with weakened immune systems are more vulnerable to ringworm infections. Healthy adult dogs are generally more resistant, but they can still carry and spread the fungus.

✅ What You Can Do at Home

While ringworm requires veterinary treatment, there are steps you can take at home to manage the infection and reduce the risk of spreading it to other pets or family members:

  • Isolate the infected dog from other pets and people until treatment begins
  • Wash your hands thoroughly after handling your dog
  • Clean and disinfect areas your dog frequents, including bedding, crates, and floors
  • Vacuum regularly to remove fungal spores from carpets and furniture
  • Launder your dog’s bedding and any washable items in hot water

It’s crucial to avoid using over-the-counter antifungal creams or remedies without consulting your vet, as these may not be safe or effective for your dog.

💡 When to Call a Vet

If you suspect your dog has ringworm, don’t wait to seek professional advice. A veterinarian can confirm the diagnosis through a physical exam, fungal culture, or other tests. Early treatment is key to preventing the infection from worsening or spreading.

Your vet may recommend one or more of the following treatments:

  • Topical antifungal creams, shampoos, or ointments
  • Oral antifungal medications for more severe cases
  • Regular medicated baths to remove fungal spores

According to VCA Animal Hospitals, treatment for ringworm typically lasts several weeks and requires consistency to fully eliminate the infection (source). Follow your vet’s instructions closely, and don’t stop treatment prematurely, even if your dog’s symptoms improve.

FAQs

Q: Can I catch ringworm from my dog?
A: Yes, ringworm is zoonotic, meaning it can spread from animals to humans. Wash your hands after handling your dog and keep their environment clean to minimize the risk.

Q: How long does it take to treat ringworm in dogs?
A: Treatment can take anywhere from 2 to 6 weeks, depending on the severity of the infection and how well your dog responds to the prescribed medications.

Q: Can ringworm go away on its own?
A: While mild cases may resolve without treatment, it’s not recommended to wait. Untreated ringworm can spread to other pets or humans and may worsen over time.
