Quick Answer

Ringworm in dogs is a contagious fungal infection causing circular hair loss, flaky skin and bald patches. It is usually treatable with antifungal medication, thorough environmental cleaning and consistent home care under veterinary guidance.

Important: This article is general information only and does not replace veterinary advice. If your dog has skin lesions or irritation, consult your vet for proper diagnosis and treatment.

If your dog has developed patchy hair loss, flaky skin, circular bald spots or unusual irritation, ringworm may be one possible cause.

Despite the name, ringworm is not a worm. It is a contagious fungal infection that can affect a dog's skin, hair and nails — and it can spread to other pets and humans.

The good news is that ringworm in dogs is often treatable with the right veterinary care and consistent home management.

At Bark with Buster®, we spend our days around real dogs through our Australian natural dog treat brand and hands-on dog care experience at Pet Stays Melbourne. One thing we've learned is this: skin problems usually improve faster when owners act early.

What Is Ringworm in Dogs?

Ringworm, also called dermatophytosis, is a fungal infection that affects the outer layer of skin, hair and nails. It can spread through contact with infected animals, shared bedding, grooming brushes or tools, contaminated surfaces and spores in the environment.

Puppies, senior dogs and dogs with weakened immune systems may be more vulnerable.

Common Signs of Ringworm in Dogs

Symptoms can vary depending on the dog and severity. Common signs include:

Circular bald patches

Patchy hair loss

Dry or flaky skin

Redness or crusting

Broken hairs

Mild itching

Nail irritation

Rough coat condition

Some dogs show only mild symptoms at first. Because many skin conditions can look similar, a vet diagnosis is important before starting treatment.

How Vets Diagnose Ringworm

Your vet may use a physical examination, UV Wood's lamp screening, hair or skin sample testing, fungal culture or laboratory testing. Getting the correct diagnosis helps treatment work faster and prevents unnecessary medication.

5 Powerful Ways to Help Your Dog Recover

1. Follow Your Vet's Treatment Plan

Ringworm often requires antifungal treatment. Depending on the case, vets may prescribe medicated shampoo, topical creams, oral medication or a combination. Do not stop treatment early just because the skin looks better — the infection may still be active.

2. Deep Clean the Environment

Ringworm spores can survive in the environment for a long time. Helpful steps include vacuuming regularly, washing bedding in hot water, cleaning bowls and toys, disinfecting hard surfaces, washing grooming tools and limiting access to carpeted rooms if needed. Consistency matters.

3. Reduce Contact With Other Pets

If you have multiple pets, ask your vet whether temporary separation is wise during treatment. Ringworm can spread between animals quickly, so early isolation can protect the rest of your household.

4. Support Healthy Skin From Within

Good overall wellbeing can support recovery. Focus on balanced nutrition, quality sleep, a low-stress routine, clean bedding and regular vet reviews. For broader nutrition guidance, read our guide to healthy foods dogs can eat.

5. Use Calm Reward-Based Care

Baths, creams and check-ups can be stressful for some dogs. Use praise and calm rewards during treatment to keep your dog relaxed and cooperative. Simple, high-value options like Fish Jerky pieces or Roo Cubes work well — small, tasty and easy to give during treatment sessions.

How Long Does Ringworm Take to Clear?

Recovery time varies. Some mild cases improve within several weeks, while stubborn cases may take longer. Your vet may recommend follow-up testing before confirming the infection has cleared. Stick with the full treatment course even if your dog looks better sooner.

Can Humans Catch Ringworm From Dogs?

Yes. Ringworm is zoonotic, meaning it can spread from animals to people. Children, older adults and people with weaker immune systems may be more sensitive. Wash hands after handling your dog and follow hygiene guidance carefully. If you or a family member develop a ring-shaped rash, see your GP promptly.

Ringworm or Something Else?

Many skin conditions can mimic ringworm, including allergies, mites, hot spots, bacterial skin irritation and seasonal dermatitis. That is why a vet diagnosis matters before starting any treatment. For general pet health guidance, RSPCA Australia has helpful resources.

Supporting Senior Dogs During Recovery

If your dog is older and also dealing with ageing concerns, softer rewards and gentler handling can make treatment sessions easier. Read our guide to best dog treats for senior dogs with sensitive teeth for soft, easy-chew options that work well for older dogs.

When to See a Vet Quickly

Book a vet visit if your dog has sudden bald patches, worsening skin irritation, multiple lesions, nail problems, persistent scratching or other pets showing symptoms. Early action helps prevent spreading and speeds recovery.

Final Thoughts

Ringworm in dogs can be frustrating, but it is often manageable with prompt veterinary treatment and disciplined home care. The key is not to panic — act early, follow the treatment plan and stay consistent.
