Ringworm in Pets: What It Is and How to Protect Your Family

Despite its name, ringworm has nothing to do with worms. It's a skin infection caused by a fungus, and it can pass between cats, dogs and people, explains the California Department of Public Health (CDPH).

How it spreads

People can catch ringworm by touching an infected animal's skin or fur, or items like pet bedding and towels. In people it usually shows up as an itchy, ring-shaped rash, typically 4 to 14 days after exposure. Children, older adults and people with weakened immune systems are at higher risk (CDPH).

Signs to look for in your pet

  • Patchy hair loss
  • Red, crusty or scaly skin
  • Brittle fur or nails

Many skin conditions look similar, so have your vet examine any suspicious patches. Regular grooming makes it much easier to spot changes early, because you're seeing and feeling your pet's whole coat every few days.

If your pet is diagnosed

CDPH recommends:

  • Keep the infected pet away from other pets and shared areas during treatment, which can take several weeks.
  • Wear gloves and long sleeves when handling them or applying medication.
  • Vacuum areas your pet uses, then disinfect hard surfaces with a fungicidal product or diluted bleach.
  • Wash bedding and towels in hot, soapy water.
  • Have all household pets checked.
  • Wash your hands with soap and water after any contact, and make sure kids do too.

During treatment, follow your vet's advice on grooming. Use dedicated tools for the infected pet and clean them thoroughly, or ask your vet whether to pause brushing.

Everyday prevention

  • Regular vet check-ups
  • Routine grooming to keep an eye on skin and coat
  • Frequent cleaning of pet beds, blankets and favorite furniture spots
