Overview
Yes, ringworm in dogs can spread to people and to other pets. It’s a contagious fungal skin infection, so it’s sensible to treat any suspicious patches carefully until a vet has confirmed what’s going on.
That said, not every circular or patchy skin problem is ringworm. Other skin issues can look similar, so it’s worth checking the signs calmly and getting proper advice if you’re unsure.
Things To Check
1. Look for round or irregular patches of hair loss, scaling, broken hairs or crusting.
2. Check whether the skin looks red, flaky or slightly raised at the edges.
3. Note whether your dog is scratching, licking or rubbing the area more than usual.
4. See if any other pets in the home have similar patches or areas of hair loss.
5. Check whether anyone in the household has developed itchy, circular skin lesions.
6. Think about recent contact with other animals, bedding, grooming tools or shared resting areas.
7. Watch whether the patches seem to be spreading or changing over a few days.
Common Causes
The most likely cause is ringworm itself, which is a fungal infection and can pass between animals and sometimes to people.
Other skin problems can look similar at first, including allergies, mites, bacterial skin infections, bites or simple irritation from grooming or rubbing.
Because several conditions can appear patchy or scaly, it’s better not to assume it’s ringworm without proper confirmation.
What To Do
Keep affected dogs apart from other pets where you can, and avoid close face-to-face contact until you’ve had advice.
Wash hands after handling your dog, bedding or grooming tools, and avoid sharing brushes, blankets or towels between animals.
Clean bedding, soft furnishings and grooming items regularly, and vacuum resting areas to help reduce the amount of loose hair and skin debris around the home.
If possible, keep track of any new patches, whether the problem is spreading, and whether anyone else in the household develops skin changes.
Don’t use human creams or random over-the-counter products on the skin unless your vet has told you to, as they may not be suitable for dogs.
When To Contact A Vet
Speak to your vet if you suspect ringworm, especially if there are other pets or people in the home who may have been exposed. A vet can confirm what it is and advise on the safest way to manage it at home.
Contact your vet sooner if the patches are spreading quickly, your dog seems uncomfortable, or the skin is becoming sore, inflamed or infected.
