Overview
Hair loss around the neck and ears can happen for several reasons, and lice is one possible cause. It often comes down to itching, rubbing, scratching or skin irritation, but it can also be linked to other skin or coat problems.
If the coat is thinning in patches, or your dog is scratching more than usual, it’s worth checking the skin closely and watching for any other changes.
Things To Check
1. Look for scratching, rubbing or head shaking, especially after walks, grooming or time outdoors.
2. Part the coat around the neck and ears and check for flakes, scabs, redness, broken skin or tiny moving insects.
3. Check whether the hair loss is patchy, symmetrical or limited to areas your dog can reach with their paws.
4. Look at the ears for discharge, smell, redness or signs of discomfort when touched.
5. Think about any recent changes such as a new collar, harness, shampoo, bedding or grooming routine.
6. Check other pets in the home for similar itching or coat changes.
7. Note whether the skin looks dry, greasy, sore or warm compared with nearby areas.
Common Causes
Lice are one possible cause, especially if your dog is itchy and you can see coat changes or evidence of skin irritation. They can lead to scratching and rubbing that thins the hair around the neck and ears.
Flea irritation, mites or other parasites can look similar and may also cause irritation in these areas.
Skin sensitivity, contact irritation from collars or grooming products, and simple friction from rubbing can also cause local hair loss.
Less commonly, ear problems or underlying skin conditions may contribute if the ears are sore or your dog is scratching at them a lot.
What To Do
Keep a simple note of when the hair loss started, whether it’s getting worse, and what your dog seems to do most, such as scratching, rubbing or shaking their head.
Use gentle grooming and avoid any harsh brushing or products on the affected area until the skin has settled.
Check bedding, collars and harnesses for rubbing or dirt, and keep the area around your dog’s resting places clean and dry.
If you live with other animals, monitor them too, because similar symptoms can point towards something shared in the environment.
If the skin looks sore, the ears seem uncomfortable, or the hair loss is spreading, veterinary advice is sensible so the cause can be checked properly.
When To Contact A Vet
Contact your vet if the skin is broken, very red or swollen, if there’s discharge or a strong smell from the ears, or if your dog seems in pain. It’s also sensible to get advice if the hair loss is spreading, other pets are affected, or the itching is not settling.
