Ringworm In Dogs



Do Dogs get Ringworm?

Ringworm is a common fungal infection that affects the skin, hair, or sometimes nails (claws) of the dogs. In medical term, it is called Dermatophytosis.

The most commonly isolated fungal organisms are Microsporum canisTrichophyton mentagrophytes, and Microsporum gypseum. This disease also occurs in cats, and other species of animals as well as humans.

Causes of Ringworm

Ringworms can be caught from a variety of sources ranging from the soil, humans and also from other pets. It can also be transferred from animals to humans.

One species of ringworm called as Microsporum gypseum is a fungus that resides in the soil so a dog who plays in soil or garden can encounter it. This can also happen when a dog comes in direct contact with an infected animal or person or touches a contaminated object like a brush, food bowls, pet clothing, bedding, couch, carpet or other household items. The skin disruptions like wounds or a flea infestation, increasing your dog susceptibility to the ringworm.

However, not all dogs can encounter the infection only from contact as the age of the dog, its immune system status, and grooming habits all affect the rate of transmission. The fungal spores responsible for the spread can remain viable for up to 18 months.

What does ringworm look like?

In dogs, the ringworm lesions refer to the areas of hair loss that are roughly circular. When these circular lesions expand, the central area heals, and hairs regrow in the middle of the lesion. The affected area of hair shafts is weak and easily broken. Usually, the lesions are not itchy, but sometimes they become inflamed and develop a scabby covering.

In a few cases, fungal infection of the nails may also occur. The claws become brittle, rough, and broken.

Symptoms of Ringworm

Due to dog fur coats, it can be challenging to see the symptoms. In mild cases of ringworms in dogs, there may be nothing noticeable at all. In severe cases, you may notice the following symptoms:

  • Hair loss, which may be patchy or circular
  • Reddened or ulcerated skin especially on the head, chest, forelegs and the ridge of the back
  • Broken hairs and poor hair coat
  • Dandruff (scales) in the depths of the coat
  • Darkened skin
  • Inflamed, Crusting and thickening of the skin
  • Dry, brittle hair
  • Itchiness may or may not be present
  • Rough and brittle claws

Treatment of Ringworm

After the vet performs a physical exam, takes a diagnostic test, and the ringworm is diagnosed, the treatment plan will depend upon the severity of the case. Usually, the treatment consists of three steps.

  • Topical therapy
  • Oral medications
  • Environmental decontamination

Topical therapy

For mild cases of ringworms in dogs, antifungal creams and ointments can be applied directly to the affected areas of dog’s skin. If the infection is wide, then an antifungal shampoo can be prescribed to treat the dog’s entire body. The infection can take several months to eradicate entirely.

Oral medications

In severe cases, your dog has to take an oral antifungal drug to eradicate the infection. The treatment usually needs to be administered for a minimum of six weeks and sometimes longer.

Environmental decontamination

The worms in dogs live on both skin and hair, so they easily transmit by loose hair on carpet and other furniture. Because of this, it is recommended to do a thorough cleaning of your home and environment to remove all contaminated hairs by vacuuming, washing down the surfaces and restrict the dog to those of areas of the house that are easy to clean in so that you can clean those areas regularly.


Dogs are our friends, family, make us laugh and feel happy with their lovely ways, and we don’t want to see them in pain. So, if you notice any signs mentioned above, immediately contact a vet and have your dog checked to receive a proper treatment.

As Ivan stated Thank you for sharing this article on ringworm in dogs. I too am a pet lover and have my own furry Kids. They give me the greatest joy and I would be lost with out them. I particularly loved this because most pet owners (that I know as well as myself) don’t do any type of reading up read up on things such as this prior to it happening, but having done so now, I see the importance of being informed before that way if something may pop up we will be more knowledgeable about it and or know what to do, if it may occur. I really enjoyed this article and look forward to reading more of them. Can the cost be expensive for treatment?

My brother has a dog, she’s about 10 months old but she’s a big girl. I can’t tell you what breed she is because we found her in Mexico in the streets as a puppy looking for warmth under our car. So yes, she is a “mut” (i don’t like that name haha) not even the vet knew what exactly she was because she has a mixture of so many things. Anyway, it’s crazy to think that our pets can get just as sick as humans. We don’t really think about it much becuase we don’t usually have our pets get sick as often as us but it’s a real thing. I never thought of Ringworm even being a possiblity so thank you so much for this information.

I’ll be forwarding this article to my brother so he can look out for Calceta (that’s her name).

Thanks for sharing so many details on this malady in dogs. I’ll take on your advice and if I see my dog behaving or showing any symptoms, I’ll make sure he gets medical attention ASAP. Are medications for ringworms available in pet stores?
