What to Do If a Dog Keeps Shaking Head and Scratching Ear

The dog shows obvious discomfort by shaking its head or by holding the head to one side and rubbing the ear along the ground. The dog continually scratches the inflamed ear, thereby increasing the inflammation. The ear feels hot, the lining is reddened and the dog may show some signs of deafness.

1. Ear mites

Puppies may develop an irritating form of ear infection caused by ear mites. These mites are small insects that inhabit the ear canal and produce an intense irritation. The puppy vigorously scratches and shakes its head producing more damage to the lining of the ear.

The ear canal becomes filled with a reddish exudate which can be difficult to remove unless the dog is anesthetized. Whole litters of puppies are affected and the infection can persist into later life. Older dogs can develop ear mites, usually after playing with an infected puppy.

Treatment of ear mites is simple once the ear canal has been cleaned. Oily drops containing an insecticide quickly control the mites. Apparent failures occur when the ear canal is so filled with the waxy exudate that medication is unable to penetrate deeply inside the ear canal.

Infected puppies should be isolated from other dogs until their condition is fully resolved to prevent spreading the ear mites to other dogs.

2. Staphylococcus ear infection

An acute ear infection involving the external tissues of the ear commonly occurs in the summer months. The dog may suddenly begin to shake its head and scratch an ear. Usually, the affected ear is held lower than normal.

An examination inside the ear flap reveals an intense reddening of the tissues often accompanied by a foul-smelling thin exudate. The tissues quickly become painful and the dog resents any handling. This condition is usually caused by a Staphylococci bacterial infection.

Prompt veterinary attention is necessary for acute ear conditions as it is vital to begin the correct treatment before too much damage is done to the sensitive ear tissues. As the condition commonly occurs in the summer months, the possibility of a grass seed lodging in the ear canal must be eliminated.

Treatment is aimed at reducing the intense irritation with the use of anti-inflammatory ointments combined with an appropriate antibiotic. The sedation of the dog is usually advisable in the early stages of treatment to avoid the dog rubbing the ear.

Antibiotics are also administered by mouth to prevent the bacterial infection from spreading to surrounding tissues.

3. Yeast Infection

Yeast infections are most common in dogs who swim or are given regular baths. Thankfully, this type of infection is easy to recognize, but it usually means there is an underlying medical issue. This could be allergies, a small tumor or damage to the inner ear.

The classic signs of a yeast infection in the ear are pawing or scratching at the infected ear, shaking of the head, a waxy discharge or scabbing where the dog has scratched.

The shape and temperature of a dog’s ear canal provide the perfect conditions for yeast to thrive. If not treated quickly, you may notice that the infection spreads to other areas of the body, leaving the skin itchy, red or flaking. Yeast infections also have a distinctive and unpleasant odor.

A yeast infection in the outer ear usually only causes mild discomfort and is easily treatable with antibiotics, however, if not caught quickly it can spread to the middle and inner ear. Once the inner ear is infected, the dog is at risk of more serious conditions such as poor balance and deafness.

4. Ear canker

The most common ear condition encountered in veterinary practice is the chronic infection of the external ear in dogs with long pendulous ear flaps. This condition, commonly called “Canker”, is not a simple disease entity in itself and therefore does not have a simple solution.

It is an aggravating and often painful condition in which the lining of the ear becomes inflamed as a result of blows, accumulation of wax, dirt, and other foreign substances, ear mites, dry eczema, soapy water or general neglect of the ears.

Any treatment must be very gentle and patiently applied. Cleanliness should be of the first consideration. All scabs, discharges, and matted hair should be removed without delay.

This is not by any means easy, as quite often a considerable amount of bathing with a warm solution of borax is necessary before the sticky mass softens and comes away.

If the canker is very bad, it is better to consult a veterinary surgeon, as touching the ear often causes intense pain and resentment, and the owner may do more harm than good in attempting to probe it.

5. Hair and Grass Seed

Other factors such as the presence of plugs of hair in the ear canal or small foreign bodies such as burrs or grass seeds may abrade the lining of the ear canal and encourage the invasion of the organisms already present within the ear.

Treatment is usually sought when the dog begins to shake or rub its ear frequently or spends long periods scratching its ears. Examination of the ears with an otoscope reveals a mess of dark, waxy deposit covering the entire surface of the external canal.

When this is removed, the skin lining of the canal is reddened and swollen, and if the condition has been present a long time, it may be so thickened that the canal is almost obliterated.

The ears must be thoroughly, but very gently, cleaned. Accumulations of matted hair must be removed and the hair plucked from the tissues surrounding the external ear to avoid future penetration into the canal.

It is usually necessary to do this under anesthesia. An ointment is then instilled into the depths of the ear and repeated applications are carried out once daily until all signs of irritation are eliminated.

Vigorous cleaning of the ear canals with cotton buds should be discouraged as this serves only to irritate the already damaged tissues and encourage further infection.

Prompt attention to ear infections early in the dog’s life should lessen the possibility of the development of chronic ear diseases.

6. Fleas and Flies

Fleas continue to be a major problem with some dogs. The warm mild weather of autumn encourages a speedy build-up of fleas around the favorite haunts of the family pet.

To control this infestation of the environment it is important to vacuum or sweep up any loose hair, as the flakes of shed skin associated with the hair provide the immature stages of the flea with nourishment while it completes its life cycle.

Most insecticidal sprays suitable for household use are safe to spray around the bedding and sleeping quarters of the dog. Pay particular attention to cracks or crevices in the woodwork or brickwork which shelter the flea eggs and immature fleas.

Dogs should be either washed or powdered with a reliable and safe insecticide.

Biting flies that attack the tips of the ears of dogs are active at the moment. These large blood-sucking flies remain a problem until the cold weather arrives. They are particularly worrying for dogs with large, erect ears, such as German shepherds or cattle dogs.

A thick black scab builds upon the tips of the ears, under which the skin can be quite raw. The scab should be removed with gentle bathing in water to which a little bicarbonate of soda has been added.

Your veterinarian can provide you with a soothing ointment to heal the inflamed tissues, and a fly-repellent cream to be applied each morning.

7. Pseudomonas Infection

This condition is caused by a bacterial infection and can be very difficult to treat due to the bacteria’s resilience to antibiotics. Pseudomonas aeruginosa are what is referred to as gram-negative bacteria. These bacteria can survive in severe conditions and trigger the production of cytokine. This causes an immune response within the body leading to inflammation.

As with other ear infections, a pseudomonas infection will present with lots of head shaking, ear scratching and redness within the ear, however, there may also be ulcers present in the ear due to this type of infection.

Treatment cannot begin until a culture has been run by a veterinarian. This will show which antibiotics the bacteria are sensitive to. In this instance, the vet will prescribe a high dosage alongside more commonplace antibiotics to ensure all bacteria is completely removed. If even a minute number of bacteria remain, the infection will return in a more severe form and will be more difficult to treat.

It is vitally important to keep the ear clean of wax, pus and discharge as these are materials that create the necessary conditions for the bacteria to survive. In extreme cases where the ear canal is swollen or blocked, a veterinarian will recommend a general anesthetic to flush the ear completely clean without causing any pain to the dog. This ensures that the liquid medication can be absorbed into the skin more efficiently.

Can an ear infection kill a dog?

We do not think of ear infections being a serious condition, however, they can cause more serious medical problems if not treated promptly. In some cases, the infection can be cause by a small tumor. If this is not alleviated, the tumor can cause severe symptoms such as problems with coordination, seizures or even death.

Although this is rare, it is a possibility, which is why it is also best to seek veterinary advice as soon as you notice signs of an ear infection. The sooner the cause is treated, the fewer symptoms the dog will exhibit and the faster they will recover.

The infection itself is not a serious condition, however, the complications it causes if left untreated can certainly cause more serious and prolonged problems for your dog. This can include frequent and recurring infections, deafness and mobility issues.

How to clean your dog’s ears at home

When cleaning your dog’s ears, the most important piece of advice is NEVER use a q-tip. This will only push wax or discharge further into the ear canal and if inserted too far, the q-tip can cause permanent damage to the eardrum. Not only is this incredibly painful, but it will most likely lead to deafness in that ear.

It is advisable to use an antibacterial cleaning solution that is free from alcohol and hydrogen peroxide as these are irritants and can actually cause the type of infections you are trying to prevent.

To apply the cleaning solution, a cotton ball or cotton gauze pad is best. They will not scratch or irritate the lining of the ears and are absorbant to help remove dirt, discharge and waxy build-up.

With your dog sitting or laying in front of you, gently lift one ear flap and squeeze the ear cleaner into their ear. Always follow the guidance on the instructions regarding the acceptable amount of solution to use. Using your thumb, gently massage the base of the ear to assist the solution in breaking up the debris within the ear canal. This process usually takes around 30 seconds.

Begin to lightly rub the outer area of the ear with a cotton ball. Remember to praise your dog for being calm and still. Slowly rub further into the ear, going no deeper than the first knuckle of your fingers. If your dog needs to shake his head at any point, this is fine, as the motion will help to remove any remaining solution from his ear canal.

When you switch ears, change to a clean cotton ball to prevent spreading bacteria or dirt between the ears.

How do you put drops in a dog’s ear?

As with the method for cleaning the ears, have your dog sit or lay in front of you. Gently lift one ear flap and squeeze the drop bottle until the prescribed number of drops is in the ear. Now, gently massage the base of the ear in small circular motions. Allow your dog to shake his head, then check for any loosened debris. You can remove this with a cotton pad and lukewarm water. Wash your hands straight away to prevent spreading the infection.

Colloidal silver for dog ear infection

Touted as a wonder homeopathic treatment for infections, many holistic and natural remedies companies swear by the use of colloidal silver liquid drops to treat ear infections in dogs.

There is no scientific proof that colloidal silver treats an infection, but many dog owners have reported seeing improvement in their dog’s condition after taking this supplemental treatment.

It works by attacking the enzymes that bacteria need to utilize oxygen. Without these enzymes, the bacteria cannot survive. The most common side effect of using colloidal silver is that it causes permanent discoloration to the teeth, gums, eyes and skin. If used for too long or in too high a dosage, it can cause more serious conditions such as kidney failure and toxic shock.

When considering the use of natural remedies, you should always consult your veterinarian. While many homeopathic ingredients are beneficial, others can cause more problems than they claim to solve.

Best dog food for ear infections

If your dog suffers from recurrent infections or those caused by allergies, your veterinarian may advise a change of diet.

The best alterations are towards brands that do not contain any wheat, gluten or additives. Many dog food companies have veterinary-approved allergy diets and this will be displayed on their packaging.

These are recipes that only use natural ingredients such as brown rice, root vegetables and beneficial supplements like omega 3 fish oil or canola oil. Your veterinarian will most likely stock specialized dog food for dogs with allergies or prone to infections.

When changing your dog’s diet, be mindful not to shock their system. This should be done slowly, ideally over a 2 week period by adding a small amount of the new food to their regular food.

Over the 2 weeks, you can begin to increase the amount of the new food and decrease the amount of the old food. If you notice loose stool, decrease the amount of the new food and add smaller amounts over a longer period so they have time to adjust.

  1. Thanks, I took my dog to the vet yesterday because she started shaking her head and scratching her left ear. But the vet did not find anything wrong. He suggested that it might be a flea. I would like to know about behavioral problems because she shakes her head when I’m around.

    1. External parasites are the dog’s worst enemies during the hot weather. Fleas, flies and mosquitoes all cause intense irritation, unless the dog has been “dressed” with a suitable repellent.

      Apart from keeping kennels and surroundings free from droppings, scraps of food and the like, all of which attract pests, the kennels and dogs should be treated at frequent intervals.

      Fleas, attacking the ears of certain breeds, notably Kelpies, Airedales, Irish Terriers, Alsatians and Collies, are a real menace to the health and well-being of the dog.

      The early onslaughts leave a nasty sore, which is aggravated by the dog rubbing his ears on the ground to dislodge his tormentors.

  2. My dog too shakes her head but also rubs the side of her face on grass, street, rug anything as soon as she eats but also the middle of the night she will wake and do it. She had her hairy ear wax removed, CT scan and has never had fleas. She also swallows a lot. Vets can diagnose her so they say allergies or behavior. I’m thinking inner ear is clogged or eustachian tube dysfunction but fluid doesn’t show up in CT scan. She’s hurting, behavior is a vet’s excuse because they don’t have an answer.
