Yorkshire terriers are prone to ear infections due to their narrow ear canals, which can trap moisture and create a perfect environment for bacteria and yeast to grow.

Ear infections can be caused by bacteria, yeast, or a combination of both.

Excessive ear wax, which can be caused by genetics or environmental factors, can also contribute to ear infections.

Yorkshire terriers are more likely to develop ear infections due to their small ear canals, which can be easily blocked by ear wax.

Symptoms and Signs

Symptoms of a Yorkshire Terrier ear infection can be quite varied, but often include redness and swelling of the ear canal, as well as a foul odor.

One common symptom is head shaking, which can be a sign that your dog is trying to relieve the discomfort caused by the infection.

A buildup of wax and discharge in the ear canal is also a common sign, but it's not always accompanied by other symptoms.

Dogs with ear infections may also exhibit pain and itchiness, which can lead to scratching and crusting around the ear flap.

Here are some common signs of a Yorkshire Terrier ear infection:

  • Redness
  • Odor (a yeasty, corn chip-like smell)
  • Itching/scratching at ears
  • Pain
  • Shaking of the head
  • Head tilt
  • Discharge
  • Scabs or crusting around the ear flap
  • Swelling of the ear flap (aural hematoma)

Signs of Infection

Dogs with ear infections often show signs of discomfort and pain. They may shake their head, scratch at the affected ear, and display dark discharge with a foul odor.

Head tilting, leaning, or rolling towards the infected ear is a common sign of inner ear infection. Your dog may also walk in circles or have difficulty staying on their feet.

Redness, swelling, and crusting or scabs in the ears are all signs of ear infection. In chronic cases, the ears may appear crusty or thickened, and the ear canals may become narrowed.

Some dogs with ear infections may develop a black or yellowish discharge, while others may have a cheesy or musty smell coming from the ear. A red or irritated ear is also a common symptom of yeast ear infection.

Here are some common signs of dog ear infections:

  • Redness

There are three main types of dog ear infections, each affecting a different part of the ear. Otitis externa is the most common type, occurring when the ear canal becomes inflamed.

Ear infections can be acute or chronic, with acute infections having a quick onset and chronic infections recurring over time. Otitis externa is often caused by exposure to the outside world, making it more prone to infections.

A yeast ear infection can be distinguished from a bacterial one by the type of discharge and odor it produces. A yeast infection typically has a darker brown discharge with a strong odor.

Here are the three main types of dog ear infections, listed for easy reference:

  • Otitis externa: inflammation of the ear canal
  • Otitis media: inflammation of the middle ear
  • Otitis interna: inflammation of the inner ear

In most cases, a dog with an otitis externa will have a yeast infection, while infections of the middle and inner ear are usually bacterial.

Causes and Prevention

Yorkshire terriers are prone to ear infections, and understanding the causes can help you prevent them. Regular grooming and ear cleaning are crucial, especially if your Yorkie loves to swim.

Moisture is a common culprit behind ear infections, particularly in dogs with long floppy ears. Trapped moisture can lead to yeast infections, so it's essential to dry your Yorkie's ears thoroughly after swimming or bathing.

Antibiotics can also contribute to ear infections by disrupting the natural balance of bacteria in the ear. If your vet prescribes antibiotics, be sure to follow their instructions carefully.

Immunodeficiency, allergies, and excessive bathing can also increase the risk of ear infections. Feeding your Yorkie sugary snacks can contribute to yeast infections, so it's best to stick to a balanced diet.

Here are some common causes of ear infections in Yorkies:

  • Trapped moisture
  • Antibiotics
  • Immunodeficiency
  • Excessive bathing
  • Yeast allergy
  • Frequent swimming
  • Exercise in humid environments
  • Feeding sugary snacks
  • Not cleaning your dog's ears often enough

To prevent ear infections, make sure to dry your Yorkie's ears thoroughly after swimming or bathing. Regular ear cleaning can also help, but be sure to use a vet-approved ear cleaning product.

Diagnosis

Your vet will need to test the ear debris or perform scans of your Yorkshire Terrier's ear to choose the right treatment.

A thorough examination of your dog's ear canal is crucial, and this can be done with an otoscope, an instrument that provides magnification and light.

Your vet will want to know the history of the problem, including the duration of any symptoms, allergies or other underlying medical conditions, and what your dog has been eating.

A physical examination will also be performed, which may include a visual assessment, examination with an otoscope, gentle palpation of the ear, microscopic examination of samples, culture of samples, and biopsies or X-rays in severe or chronic cases.

Here are some tests your vet may use to diagnose ear infections:

  • Cytology: This test uses special stains on the swab of debris to color the microscopic bacterial cells or yeast.
  • Culture/sensitivity testing: This test uses special medium/broth to grow and identify the specific bacteria or yeast that are causing the infection.
  • Blood testing: This test may be needed to check for endocrine disease as an underlying condition.
  • Skull X-rays, CT scan, or MRI: These tests may be needed to assess the extent of severe or inner ear disease.

Treatment and Management

If your Yorkshire Terrier has a severe ear infection, hospitalization for intravenous fluid therapy may be necessary to control nausea and prevent dehydration.

Your veterinarian will prescribe the appropriate medications, which may include antibiotics or anti-fungal medications, and must be given precisely as prescribed.

In some cases, surgery may be required to drain the middle ear cavity or remove the external ear canal if the infection is severe or chronic.

Most dogs recover uneventfully from ear infections, but if your dog is experiencing frequent or chronic ear infections, your vet will likely recommend additional testing to determine if there is an underlying cause.

To prevent the recurrence of infection, it's essential to follow your veterinarian's instructions closely and return for any recommended recheck appointments, and to finish the full course of medication even if your dog appears to be getting better.

Otitis Interna Treatment

Otitis interna is a serious condition that requires prompt treatment. If your dog can't eat or drink normally due to nausea or disorientation, hospitalization for intravenous fluid therapy may be necessary.

Nausea must be controlled, and dehydration avoided. Your veterinarian will prescribe the appropriate medications to treat the underlying infection.

Antibiotics are commonly used to treat bacterial infections, and must be given precisely as prescribed for a minimum of six to eight weeks. Anti-fungal medications may be prescribed if the infection is fungal.

If your dog has an altered balance, restrict his activity during treatment to prevent falling injuries. You may also need to temporarily hand-feed your dog, as reaching down into a dish may stimulate nausea.

In severe cases, surgery may be required to drain the middle ear cavity or remove the entire external ear canal. This is usually reserved for dogs with fluid build-up in the middle ear, osteomyelitis, or a mass in the middle ear or eustachian tube.

Most dogs recover uneventfully from ear infections, but if your dog is having frequent or chronic ear infections, your vet will likely recommend additional testing to determine if there is an underlying cause.

Long-term management may include weekly preventative ear cleaning and/or a diet change, as food allergies can be an underlying cause of infections.

If your dog has otitis interna, there's a risk of permanent damage to their balance and hearing. A permanently altered sense of balance and persistent signs of Horner's syndrome are two potential long-term complications of inner ear infection.

Your dog may also become permanently deaf in the affected ear. This is a serious consequence of otitis interna, and it's essential to take immediate action to prevent it.

Dogs with otitis interna may require a two to four-month course of oral antibiotics to prevent a relapse. This is a common treatment plan for this condition.

The altered sense of balance that accompanies otitis interna typically improves within two to six weeks. Small dogs may recover their balance more quickly than large breeds.

Otitis Interna Definition

Otitis interna is a serious condition that affects the inner ear of dogs. It's caused by an infection, most often bacterial, but fungus can also be a culprit.

The infection can spread from the external ear canal, where ear mites or other issues can create a problem. Inner ear infections can also develop if disease exists in one ear canal or if a benign polyp grows from the middle ear.

A foreign object, like grass seed, can set the stage for a bacterial infection in the inner ear. This is why it's essential to keep an eye on your dog's ear health, especially after outdoor activities.

The inner ear plays a crucial role in balance and hearing, so otitis interna can have significant effects on your dog's quality of life.

Frequently Asked Questions

Can dog ear infection go away by itself?
