Overview
If you think your dog has ringworm, the safest approach is to treat it as a skin change that needs checking rather than trying to guess the cause. Ringworm can be one possibility, but other skin problems can look similar, so it’s best not to assume.
It’s sensible to look for the pattern of the rash, note whether it’s spreading, and keep your dog away from other pets and people until you’ve got clearer advice.
Things To Check
1. Look at the shape of the area. Ringworm often starts as a round or patchy area of hair loss, but other skin issues can look similar.
2. Check whether the skin is red, scaly, crusty or broken, and note if there’s any discharge or bleeding.
3. See if your dog is itchy, licking, scratching or rubbing the area more than usual.
4. Check if there are more than one patch, or if the problem seems to be spreading to other parts of the body.
5. Think about whether any other pets or people in the home have recently developed skin changes, as ringworm can pass between animals and people.
6. Consider any recent contact with other animals, grooming salons, kennels or shared bedding, bowls and brushes.
7. Note whether your dog seems otherwise well, or whether they also seem dull, sore or uncomfortable.
Common Causes
The most common reason for ring-shaped hair loss or scaly patches is a fungal skin infection, but that’s not the only possibility.
Other common causes include allergies, bacterial skin infections, mites, irritation from grooming products, and licking or scratching that damages the coat and skin.
Less commonly, a patch that looks like ringworm may be linked to another skin condition that needs a vet exam or testing to identify properly.
What To Do
Keep the area clean and dry, and avoid bathing or applying anything unless you’ve had advice on what’s suitable for dogs. Try not to let your dog share beds, brushes, towels or grooming tools with other pets while you’re sorting it out.
Wash your hands after touching the area, and if possible, limit close contact with children, older people or anyone with a weaker immune system until you know what’s going on.
Take a few clear photos so you can compare whether the patch is changing. If the area is growing, more patches appear, or your dog seems uncomfortable, contact your vet for advice on the next step.
When To Contact A Vet
Speak to your vet if the patch is spreading, your dog is very itchy or sore, several pets or people in the home are affected, or the skin looks infected. Your vet can help confirm what’s causing it and advise on the most suitable way to manage it.
