Overview
Patchy hair loss on a dog’s face can happen for several reasons, and mange is one possible cause. It can also be linked to allergies, rubbing, minor skin infection, mites, or irritation from something your dog has been brushing against.
The pattern, how quickly it’s appeared, and whether there’s itching, redness or scabbing can all help narrow down what’s going on.
Things To Check
1. Look at exactly where the hair loss is. Around the eyes, muzzle, ears or cheeks can sometimes point towards different causes.
2. Check for itching, rubbing, face scratching or head shaking, as these often suggest irritation or discomfort.
3. Look closely for redness, scabs, flakes, crusting, spots, discharge or broken skin.
4. Notice whether the skin looks greasy, dry, thickened or sore.
5. Think about whether anything has changed recently, such as a new shampoo, bedding, food, grooming routine or outdoor exposure.
6. Check whether any other pets in the household have similar patches, itching or skin changes.
7. Watch for patterns such as worse symptoms after walks, play, grooming or contact with other animals.
Common Causes
Mange is one possible cause, especially if the hair loss is patchy and the skin looks irritated, scaly or crusted. Different types of mites can affect dogs in different ways, and facial areas are sometimes involved.
Allergies are also common. Dogs can react to something in the environment, food, or contact irritants, and the face may be affected if they rub or scratch there a lot.
Skin infection can sometimes develop after irritation or scratching. This may cause small patches of hair loss, redness, soreness or crusting.
Rubbing, pressure or trauma from collars, harnesses, fencing, bedding or grooming can also lead to localised hair loss. Less commonly, hormonal or immune-related skin problems may play a part, especially if the hair loss spreads or keeps returning.
What To Do
Keep a simple note of when you first noticed the patchy hair loss, whether it’s changing, and any signs of itching or discomfort. Photos can be helpful if the area changes over a few days.
Try to avoid over-washing, harsh shampoos or any home remedies that could irritate the skin further. Keep bedding clean and check for anything in the environment that might be rubbing the face or causing contact irritation.
If your dog is scratching or rubbing the area, try to reduce further irritation where you can and monitor whether the skin looks more inflamed. If there are other pets with skin issues, keep an eye on whether symptoms seem to be spreading.
When To Contact A Vet
Speak to your vet if the hair loss is spreading, the skin looks sore or infected, your dog seems itchy or uncomfortable, or there are scabs, discharge or swelling. Facial skin problems can have several causes, and a vet can check for mites, allergy, infection or other skin disease.
It’s also sensible to get advice if more than one pet is affected, or if the problem keeps coming back.
Products That May Help
If your dog’s face looks patchy or irritated, gentle coat and skin care can be useful as part of a sensible home routine while you monitor the area and speak to your vet if needed.
