A dog excessively scratching its ear can be worrying for any dog owner. While an occasional itch is normal, constant scratching may point to an underlying issue that needs attention.
We outline the common causes of excessive ear scratching in dogs, what you can do, and when to seek veterinary care.
Dog Excessively Scratching Ear: Why It Happens
Excessive ear scratching in dogs is often linked to discomfort or irritation in the ear canal. This can stem from ear infections, ear mites, allergies, trapped foreign objects, or even excessive wax buildup.
In some cases, the scratching may be so persistent that it leads to redness, sores, or even bleeding around the ear.
Understanding the possible causes is essential to prevent the condition from worsening and to ensure your dog finds relief.
Dog Excessively Scratching Ear: Common Causes
Ear Infections
Ear infections are one of the most common reasons a dog excessively scratches its ear. Bacteria or yeast can thrive in the warm, moist environment of the ear canal, leading to intense itching and irritation.
You may notice your dog shaking its head frequently, tilting its head, or showing sensitivity when the ear is touched.
A strong odor or discharge from the ear may also be present. Left untreated, infections can become painful and potentially spread deeper, making early care very important.

Ear Mites
Ear mites are tiny parasites that can infest a dog’s ear canal, causing relentless scratching. These pests feed on wax and oils in the ear, and their presence leads to intense itching.
Signs of ear mites often include dark, crumbly debris that looks like coffee grounds inside the ear, head shaking, and constant pawing at the ears.
While more common in puppies, adult dogs can also be affected. Without treatment, ear mites can cause significant discomfort and secondary infections.
Allergies
Just like humans, dogs can suffer from allergies that trigger itchy ears. Food sensitivities, environmental allergens such as pollen or dust, and even certain grooming products may lead to inflammation in the ear canal.
When allergies are the culprit, scratching may affect both ears and can sometimes coincide with skin irritation, paw licking, or chronic ear infections.
Allergic reactions tend to be recurring, so addressing the root cause is key to reducing ear scratching.
Foreign Objects
Sometimes, a foreign object such as grass seeds, dirt, or small debris can get lodged in the ear canal. This causes immediate irritation and drives a dog to scratch or shake its head excessively.
Foreign objects can lead to redness, swelling, and even injury if they remain stuck for too long.
Because dogs cannot remove these items on their own, veterinary assistance is often needed to safely clear the blockage.
Excessive Ear Wax
A buildup of wax inside the ear canal may also be the reason behind persistent scratching. Some dogs naturally produce more ear wax, and if it accumulates, it can cause irritation or even create an environment for infections.
You might notice a yellowish or brownish waxy substance, along with an occasional odor. While mild wax buildup may not always be serious, consistent scratching suggests the need for cleaning or further evaluation.
Skin Conditions
Certain skin conditions, such as dermatitis or fungal infections, may also extend to the ear area, leading to constant scratching. In these cases, redness, bumps, or flaky patches may appear around the ear in addition to itching.
Skin-related issues often need medical management, as scratching can worsen the condition and lead to open wounds or secondary infections.

Dog Scratching Ear and Shaking Head at Night
Scratching the ear and shaking the head at night often suggests irritation or discomfort that becomes more noticeable during rest.
Common causes include ear infections, mites, foreign objects, or trapped moisture in the ear canal. Allergies can also worsen symptoms at night.
If this behavior disrupts sleep or continues for several nights, veterinary evaluation is needed to identify the cause and prevent worsening infection.
Dog Keeps Scratching Ear and Licking Paw
When a dog scratches its ear and also licks its paw, it often points to allergies, either environmental or food-related.
Dogs with allergic reactions commonly show symptoms in multiple areas, including ears, paws, and skin.
Ear infections may also cause secondary behaviors like paw licking due to generalized discomfort.
This pattern usually requires both ear treatment and allergy management to fully resolve.
Dog Excessively Scratching Ear and Shaking
Excessive ear scratching combined with head shaking is a strong sign of ear irritation or infection. This may be due to bacterial or yeast infections, mites, wax buildup, or even a foreign object in the ear canal.
The shaking occurs as the dog tries to relieve pressure or discomfort inside the ear.
Because infections can worsen quickly and affect hearing or balance, prompt veterinary treatment is needed.
Old Dog Excessively Scratching Ear
Excessive ear scratching in an older dog is often caused by ear infections, ear mites, allergies, or buildup of wax and debris.
Senior dogs are also more prone to chronic ear problems due to weaker immunity and long-term inflammation.
Sometimes, underlying issues like skin disease or hormonal imbalance can also contribute.
If the scratching is persistent, it can quickly lead to pain, swelling, or ear hematomas, so it should be checked early to prevent complications.
Dog Excessively Scratching Ear: What to Do
If your dog is excessively scratching its ear, start by gently examining the outer ear for redness, discharge, or debris. Use a soft cloth to wipe away any visible dirt, but avoid inserting anything deep into the ear canal.
Keeping ears dry is important, as moisture can worsen infections or irritation. After swimming or bathing, gently dry your dog’s ears with a towel.
You can use a vet-approved ear cleaner to help manage mild wax buildup. However, avoid using human ear products or remedies without veterinary guidance.
If you suspect allergies, keeping a diary of your dog’s diet, environment, and flare-ups may help identify triggers. Small changes, such as switching food or avoiding certain products, may provide relief.
Monitor your dog closely. If scratching continues despite basic care, professional evaluation is needed to identify the root cause.
When to Call or Visit Your Vet
If your dog shows signs of pain, swelling, foul odor, or discharge from the ear, contact your veterinarian promptly. These symptoms often indicate infection or mites that require medical treatment.
Persistent head shaking, tilting of the head, or loss of balance are also concerning signs that should not be ignored.
If your dog’s scratching leads to sores, bleeding, or hair loss around the ears, veterinary attention is necessary to prevent complications.
Even if the symptoms seem mild, ongoing scratching is not normal and should be checked to avoid long-term damage to the ear.

Dog Excessively Scratching Ear: Treatment
Treatment depends on the cause of the ear problem. The veterinarian may examine the ear canal and prescribe medicated ear drops for bacterial or yeast infections, anti-parasitic treatment for mites, or allergy management if the cause is chronic inflammation. Pain relief may also be given if the ear is very sore.
Early treatment is important because untreated ear issues can become chronic, painful, and even affect balance or hearing over time.
Key Takeaway
Excessive ear scratching in dogs is usually a sign of discomfort and should not be overlooked. Whether the cause is an infection, mites, allergies, or another condition, timely care can bring your dog relief and prevent serious problems.
If basic at-home measures do not improve your dog’s condition, or if concerning symptoms appear, seeking veterinary advice is the best step. By addressing the issue early, you can help your dog stay healthy, comfortable, and free from ear pain.
