What Does Ringworm Look Like On a Dog?

Despite its name, ringworm is a fungus, comparable to athlete's foot. It generates infective seeds known as spores, which are difficult to eliminate in the environment. Ringworm can infect the skin of all animals, including dogs. Today, our Novato vets discuss ringworm in dogs and what it looks like.


What does ringworm look like in dogs?

Ringworm can show in a variety of ways in dogs, most commonly as patches of hair loss with a crusty coating, or (rarely) as asymptomatic. Ringworm patches in some dogs resemble a grey, scaly patch, while in others they resemble a scarlet lesion. Dogs who are young, elderly, or have long hair are more likely to be impacted.

Bring your dog to the vet if you notice any of the following symptoms:

  • Dry, brittle hair
  • Inflamed, red skin rash
  • Circular or patchy areas of hair loss
  • Scales that look like dandruff
  • Scabs or lesions on the skin
  • Darkened skin
  • Reddened skin
  • Inflamed folds of the skin around the claws or nails
  • Itchiness

How does ringworm get diagnosed?

If you suspect your dog has ringworm, take them to the clinic immediately since they will require treatment to be cured. Vets utilize a few different procedures to diagnose ringworm. Your veterinarian may examine your dog's fur and skin using an ultraviolet lamp. This is the most trustworthy test, however, it takes 10 days to provide findings.

What are the treatment options for ringworm?

Ringworm may be readily treated with oral drugs as well as several lotions, sprays, and shampoos. If your dog or other pets have a history of skin issues, take them to the veterinarian as soon as you discover any symptoms. Depending on the severity of the infection, your veterinarian may advise treating all of your dogs at the same time. Ringworm can cause hair loss, rashes, and other symptoms that, to the untrained eye, appear to be another illness. If you suspect your dog has ringworm, there are several effective treatments available.

Depending on the severity of your dog's ringworm condition, your veterinarian will assist you in selecting the appropriate remedy for them. The following are the most common treatments for ringworm:

  • Topical medication
  • Anti-fungal oral medication
  • Environmental decontamination (such as deep cleaning a carpet to keep the infection from spreading)

How can I keep ringworm from spreading?

Ringworm is spread by direct contact with an infected animal or through a contaminated substance. If surfaces are not cleaned, ringworm can linger on them or become trapped in the fibers of carpets, curtains, and linens.

A pet may be a ringworm carrier even if there are no obvious signs. Ringworm spores are tenacious and may survive in the environment for a long time, so confine your affected dog to a single room while you treat them. If you heal your dog but do not eliminate the virus from your home, your dog may become sick again.

To eliminate the spores, soft furniture and carpets should be vacuumed thoroughly and regularly, or steam cleaned. Disinfectants should be used to clean any other things. Consult your veterinarian about which disinfectants are effective.

How long should I quarantine a dog with ringworm?

Ringworm can endure anywhere from 6 weeks to 18 months, although it is not as deadly as other illnesses or diseases. It will not kill your dog and will not cause irreparable damage. The best thing you can do is confine your dog to a separate room in your house and limit contact with your other pets or family members while the therapy is ongoing.

Ideally, you should try and keep your dog quarantined for about six weeks while you battle ringworm. Although this might sound difficult, it should be infinitely easier, and much less expensive, than having to constantly battle ringworm.
