Overview
Hair loss around a dog’s eyes and muzzle can happen for several reasons, and ringworm is one possible cause. It’s worth checking the skin closely, but you can’t confirm the cause from the pattern alone. Other common causes include irritation, allergies, mites, grooming friction and skin infection.
Things To Check
1. Look at whether the hair loss is patchy, symmetrical or spreading, and note how quickly it appeared.
2. Check for redness, scaling, crusts, broken hairs, scabs, swelling or any discharge from the eyes or nose.
3. See if your dog is rubbing the face, scratching, pawing at the muzzle or seems sore when touched.
4. Think about recent changes such as new grooming, shampoos, bedding, cleaning products or contact with other animals.
5. Look for hair loss elsewhere on the body, especially around the ears, paws, legs or tail.
6. Check whether other pets or people in the home have new itchy or circular skin lesions, as ringworm can spread between animals and humans.
7. Note any signs of general illness such as reduced appetite, lethargy or eye discomfort.
Common Causes
Ringworm is one possible cause and often leads to patchy hair loss with broken hairs, scaling or mild crusting. Despite the name, it’s a fungal skin problem rather than a worm.
Allergies are also common and may cause facial rubbing, redness and thinning hair from repeated irritation.
Mites, including demodex, can sometimes affect the face and muzzle and may cause patchy hair loss or skin changes.
Skin infection, contact irritation and friction from collars, harnesses or grooming can also lead to hair loss around the face.
What To Do
Keep a close eye on the area and take clear photos every few days so you can spot any change.
Avoid using human creams or harsh antiseptics on the face unless your vet has advised them.
Wash hands after handling the area and try not to let your dog rub on soft furnishings if ringworm is a possibility.
If you have other pets, keep a sensible eye on them too for any skin changes, since some causes can spread within a household.
If the area is getting worse, your dog seems uncomfortable, or the skin changes are not settling, veterinary advice is appropriate.
When To Contact A Vet
Contact your vet if the hair loss is spreading, your dog seems itchy or sore, there is eye involvement, or you notice crusting, swelling or discharge. It’s also sensible to get advice if ringworm is suspected, because the skin needs the right diagnosis and it can spread to other pets and people.
Products That May Help
If your dog needs regular washing or gentle coat care while you’re keeping an eye on the skin, a suitable grooming routine may help support day-to-day hygiene.
