Ringworm in dogs – symptoms, treatment, and prevention in Dubai

What is ringworm in dogs?

• A contagious skin infection affecting the skin and sometimes the claws.
• It’s usually acquired through direct contact with infected dogs or contaminated items, such as brushes, bedding, or furniture.
• Several fungal species can cause ringworm in dogs.
• Healthy skin usually resists infection, but small scratches or a weakened immune system allow the fungus to take hold.
• Ringworm may look like mange, flea allergy, or bacterial infections.
• Though serious illness is rare, treatment is recommended to prevent spread and relieve discomfort.

If you think your dog might have ringworm, call your vet for help and advice on diagnosis and safe, effective treatment options.

Symptoms of ringworm in dogs

• Small circular patches of hair loss, often with scabs or a crusty edge
• Dry, scaly skin; dandruff
• Red, inflamed or darkened areas of skin
• Itching, scratching or grooming more than usual
• One patch or widespread areas of skin
• Nail beds that are red and inflamed, with dry or darkened nails (claws)
• Claws that become brittle, cracked, or deformed

Because many skin problems have a similar appearance, only a vet can confirm if your dog has ringworm.

Dogs more at risk of ringworm

• Puppies: have immature and weaker immune systems
• Dogs with weakened immune defences (immunocompromised): dogs suffering from chronic illness or taking certain medications
• Yorkshire Terriers: known to suffer more severe infections
• Hunting and outdoor dogs: more risk from contact with wildlife or community animals
• Dogs visiting grooming salons or boarding kennels: shared brushes, clippers, or bedding and close exposure to other dogs

Considerations:

• Warm and humid conditions in Dubai help spores survive longer in the environment.
• Multi-dog households have a greater risk of ongoing reinfection cycling between pets unless all dogs are checked and treated.

Can humans and other pets get ringworm from dogs?

Yes. Ringworm is a zoonotic disease, meaning people can catch it from infected dogs.

Children and people with weakened immunity are more at risk. Signs include small, round, red patches of itchy skin. If you notice these changes, contact your GP and mention possible exposure to an infected pet.

Diagnosing ringworm in dogs

Ringworm can be tricky to diagnose because it can look like other skin conditions. Testing options include:

• Wood’s lamp test: certain types of fungus glow green under UV (ultraviolet) light.
• Microscopy: examining hairs under a microscope; looking for fungal spores and filaments.
• Fungal culture: growing the fungus in a lab from samples of hair, skin, or claws (takes 2–3 weeks).
• ‘PCR’ testing for fungal DNA: the newest test. Suitable for initial diagnosis, but not post-treatment follow-up, as it doesn’t distinguish between living and dead ringworm parasites.

Some dogs carry spores without visible signs, so your vet is likely to recommend testing all pets in your home.

Veterinary treatment for ringworm in dogs

Because ringworm spreads so easily, treatment is aimed at eliminating the fungus from the dog and its environment, rather than simply treating the symptoms.

• Topical prescription antifungal creams or ointments: for mild, localised infections affecting a small area.
• Medicated shampoos or washes: combined with oral (by mouth) prescription antifungal drugs for more severe/established cases.
• Oral prescription antifungal medication: requires a long course of treatment, several weeks to months.
• Supportive care: for very unwell dogs, particularly those with other illnesses.

Key factors

• Treatment takes time, often several months, and stopping early usually causes relapse.
• Your vet will repeat ringworm tests before confirming your dog is clear of infection.

It’s also important to check and possibly treat other pets in the household to prevent constant reinfection.

Tips to prevent ringworm from spreading

Ringworm spores can survive for months in the environment, even longer in Dubai’s hot, humid climate. Cleaning is as important as medical treatment.

• Keep infected dogs in an easily cleaned area, separated from other pets.
• Wash bedding, toys, clothing, and bowls regularly: ideally twice in succession on the hottest cycle, using your normal detergent.
• Vacuum carpets, sofas, and dog beds frequently to remove shed hair.
• Disinfect grooming tools and clippers after every use.
• Wear gloves and change your clothes after handling infected pets.
• Children and people with weakened immunity should avoid direct contact with affected dogs until treatment is successfully completed.

When to worry about ringworm in dogs

Contact your vet if:

• You notice patches of hair loss or scaly skin.
• Your dog becomes very itchy.
• The affected areas are spreading, swollen, or starting to cause your dog distress.
• Your dog develops abnormalities with their claws.

Early identification and treatment can help prevent the spread and speed recovery.
