Overview
Facial hair loss and scaly skin in dogs can be caused by mange, but it’s not the only possibility. Other common reasons include skin irritation, allergies, infection, ringworm, or self-trauma from scratching and rubbing, so it’s best to look at the full picture rather than assume one cause.
Things To Check
1. Check whether the hair loss is patchy, symmetrical, or limited to the face, muzzle, ears or around the eyes.
2. Look closely for redness, dandruff-like scaling, crusts, scabs, broken skin, discharge, or areas that feel warm.
3. Note whether your dog is itchy, rubbing the face, shaking the head, or scratching more than usual.
4. Think about whether the problem started after contact with another animal, a new bedding area, a change in grooming, or time outdoors in a different place.
5. Check for similar signs elsewhere on the body, especially the ears, paws, belly, or around the eyes.
6. Look for any change in your dog’s comfort, appetite, energy, or behaviour.
7. If it’s safe to do so, part the coat gently and see whether there are fleas, flea dirt, or any obvious skin debris.
Common Causes
Mange is one possible cause, especially if the skin is scaly, irritated, and the hair loss is spreading. It’s often considered when facial changes come with itching or crusting, but it can’t be confirmed just by looking.
Allergies are another common reason, including environmental or food-related irritation. These can make dogs rub their faces and overgroom, which can lead to hair loss and flaky skin.
Skin infections can also sit behind the problem. Bacterial or yeast overgrowth may make the skin sore, greasy, scabby, or flaky, and the hair may fall out in patches.
Ringworm and other fungal skin problems can sometimes cause hair loss with scaling too. These can look similar to other skin conditions, so they’re easy to mix up at home.
Less commonly, the issue may be linked to parasites other than mange, contact irritation, or a hormonal skin problem, especially if the pattern is ongoing or keeps returning.
What To Do
Keep a note of when you first noticed the change and whether it’s getting worse, staying the same, or improving. A few clear photos over several days can help you track the pattern.
Try to avoid harsh shampoos, home remedies, or picking at flakes and crusts, as this can make the skin more sore and muddy the picture.
Use a gentle, calm grooming routine and keep bedding, collars and any shared resting areas clean so you can reduce extra irritation while you monitor the skin.
If the area is itchy, try to stop repeated rubbing or scratching where you can, since that often makes facial hair loss look worse than it started.
If the signs are spreading, your dog seems uncomfortable, or the skin changes aren’t settling, it’s sensible to speak to your vet for a proper skin check.
When To Contact A Vet
Contact your vet if the skin is rapidly worsening, your dog seems very itchy or painful, there is swelling, discharge, or broken skin, or if the problem is affecting the eyes, ears, or a large area of the face.
You should also get advice if more than one pet in the home has similar signs, or if the skin issue is not improving with sensible home monitoring.
Products That May Help
If your dog has facial hair loss and scaly skin, a gentle skin and coat routine can help you keep an eye on changes and support day-to-day grooming. The arlo.® Pet Care collection may be useful as part of that routine.
