Ringworm in dogs: why and how to protect your dog from ringworm

Ringworm in dogs is a common condition – but despite the name and appearance, ringworm isn’t actually a worm. Ringworm is a fungal infection that affects your dog’s skin, and can progress to other areas of the body, such as the claws.

Known medically as dermatophytosis, ringworm is a highly contagious – and usually painless – condition, much like athlete’s foot. Ringworm is spread by direct contact with another dog, animal or person with the condition, or through contact with the bedding, bowls or equipment used by another infected dog.

Because ringworm isn’t a parasite – unlike roundworm or tapeworm – traditional worming treatments won’t get rid of the condition. 

Does my dog have ringworm? Identifying ringworm in dogs

Ringworm gets its name from its appearance – raised, circular areas of skin about the size of a 1p coin. Patches most commonly appear on the dog’s head, ears, paws and legs, and can have a worm-like appearance – hence the name. These crusty-looking lesions often lead to patches of hair loss in your dog. 

Did you know? 

Ringworm is what’s known as a zoonotic condition, which means it can be passed between dogs, other animals, and even humans!

Top tips to avoid catching ringworm from your dog

Ringworm can be hard to get rid of, because it’s easily passed back and forth between infected dogs and their owners. Follow these top tips for avoiding ringworm: 

  • Thoroughly wash your dog’s bedding and bowls, and keep soft furnishings and carpets clean. 
  • Always wear gloves when treating your dog’s ringworm, and wash your hands thoroughly each time you touch your dog.
  • Dust and hoover your home regularly to remove ringworm spores.
  • Wash clothes, towels and bedding regularly.
  • Don’t let your dog sleep on your bed or sofa while they’re infected.

Ringworm treatment for dogs

Ringworm can easily be confused with other skin conditions, so be sure to get a diagnosis from your vet before treating your dog. Ringworm treatment usually involves an antifungal medication or an antifungal shampoo – both of which can help to clear up the condition quickly and effectively.
