Ringworm in Cats and Dogs

RingwormBoy_And_Dog_200.jpg
Does My Pet Have Ringworm?

In animals, ringworm usually appears as a crusty or scaly patch on the skin with some hair loss. The affected areas may become red or irritated looking. Ringworm is sometimes itchy. 

Occasionally, ringworm will fluoresce under a black light. 

Unfortunately, a cat can have ringworm and not show any skin lesions at all. 

A fungal culture is the best test to diagnose ringworm; it typically takes one to three weeks to get results. Fungal cultures will also be used to monitor the progress of treatment.

Call your veterinarian if you notice any hair loss or excessive itching in your dog or cat.

What is Ringworm?

Ringworm is not actually caused by a worm, but rather by a fungus that infects the outer layer of skin and hair. It is a zoonotic disease, meaning it can be transmitted from pets to humans, or people to pets.  There are numerous species of ringworm. It is most commonly recognized in cats (often kittens) and dogs, although rabbits and rodents can also become infected. Ringworm can be very contagious.

Can I Get Ringworm from My Pet?

Yes. Anyone that has come into contact with the infected animal or its environment has the chance of contracting ringworm. In people, the infection may appear on the skin as a ring with reddish borders and is usually itchy. If you have any concerns about ringworm in family members, please seek advice from your physician.

How is Ringworm Treated?

Ringworm is easily treatable in humans with only topical medication. However, this is not the case with pets. In order to eliminate ringworm from animals, topical and oral anti-fungal medications are required, and it often takes months for complete resolution.  Oral medication is either itraconazole or fluconazole.  Topical medications are daily miconazole or clotrimazole creams plus weekly lime sulfur dips.  Once the skin starts to improve, a fungal culture  will be obtained and sent out to monitor the status. As soon as there is one negative culture, a second culture will be sent to the lab.  Dermatologists recommend that treatment be continued for one month beyond the second negative culture.  It is important that your pet receive their medication and treatment regularly.

How Do I Clean My House?

  • Ringworm spores can survive in the environment for two years. Pets and people can become re-infected if the house isn’t properly cleaned.
  • The best product to kill ringworm is bleach (1:10 dilution with hot water). You can also use Lysol with Bleach or 409. Make sure to use any product liberally and repeat cleaning daily.
  • Vacuum carpets, floors, and furniture frequently and dispose of the vacuum bag immediately.
  • All curtains, comforters, etc. should be dry cleaned at a professional cleaner.
  • Clean all air vents and change filters often.  
  • It is also recommended that items that cannot be bleached (e.g. floor rug, couch, etc.) be placed outside in the sun on a hot day. 
  • Wash all sheets, blankets, towels, pet beds, plush toys, pet brushes, etc., bleaching items when possible.
  • Throw away anything that cannot be fully cleaned.

Be sure to talk to your veterinarian if you notice any changes in your pet's behavior or if your pet does not appear to be improving.

    I love Balboa Pet Hospital! Balboa Pet Hospital's staff is amazing! The staff is knowledgeable, caring and above all honest! I feel confident that my pets are getting the best possible care there. The staff has always taken time to answer all of my questions and if I think of something after my appointment, I can just email! I know I won’t have to wait too long for response.

    Unfortunately, this year I’ve had to make some really difficult decisions. The compassion the staff showed to both my pet and I made these unbearable times tolerable. I am indebted to both Dr. Del Rosso and (the wonderful) Dr. Ravn for their kindness, compassion and dedication.

    If you are new to the area or just looking for a new vet, please give Balboa pet Hospital a call!

    LOVE everything about this place!!! The people are all super nice & caring. I never feel like they’re trying to sell me stuff I don’t need. The vets (especially Dr. Alice Chan) are wonderful, I always fee; comfortable coming here whenever Walle has an issue. They even help me file the insurance claims after each visit! Would highly recommended any pet owners to see them for their fur-baby needs.

    My dog has been a regular patient since 7 years ago. Once in a while we visit other hospitals due to time conflicts. However, we always go back to Balboa Pet Hospital. My dog has bad allergy and the doctors and assistants always follow up with us after the treatments or visits, help us submit the insurance claims. It’s not a cheapest place to go but their patience and caring are irreplaceable.

    I’m glad to have found Balboa Pet Hospital near my home. It’s definitely a hidden gem! Dr. Chan saw my dog, Oreo, for her skin problem last week, and my three cats, Pepper, Tofu and Cola, today for annual check-up. She’s very patient (especially with Oreo who’s shy to strangers), knowledgeable and approachable. The front staffs are also very friendly and helpful. They are so prompt to reply my email (within a few hours when I checked back my mailbox). All my pets are about 1-year-old and I’ll definitely bring them here for their health issues/checkup in many years followed.

    Brought my dog here for a checkup and some minor concerns. Dr. Chan was very professional. She got my dog the treatment he needed and answered all my questions regarding my concerns. The rest of the staff were very friendly and gentle with my dog. You could tell that the staff are genuine animal lovers; definitely something you want when you entrust the health of your pet to someone.
