Shih Tzus are prone to ear infections due to their floppy ears, which trap moisture and create a perfect environment for bacteria and yeast to grow.
Bacterial ear infections in Shih Tzus are often caused by Staphylococcus pseudintermedius, a common skin bacterium.
Yeast ear infections, on the other hand, are typically caused by Malassezia, a type of fungus that's naturally found on the skin and in the ears of dogs.
Regular ear cleaning and checking for signs of infection, such as redness, swelling, and discharge, can help prevent ear infections in Shih Tzus.

What Causes?
Shih Tzus are prone to ear infections due to their floppy ears, which can trap moisture and create a warm, humid environment that's perfect for bacteria and yeast to grow.
Moisture is a major contributor to ear infections in dogs, and Shih Tzus are no exception. Trapped moisture can lead to a yeast infection, especially if your dog has long floppy ears.
Ear infections can be caused by a combination of bacteria and yeast, and in puppies, ear mites can also be a source of infection. In Shih Tzus, allergies can lead to ear disease, with about 50 percent of dogs with allergic skin disease and 80 percent of dogs with food sensitivities experiencing ear problems.
Regular grooming and ear cleaning are essential for preventing ear infections in Shih Tzus. Use a vet-approved ear cleaning product and dry your dog's ears thoroughly after bathing or swimming.
Here are some common causes of ear infections in Shih Tzus:
- Foreign bodies, such as grass awn or foxtails, that get into the ear
- Excessive moisture from bathing or swimming
- Food allergies
- Environmental allergies
- Endocrine issues, such as hypothyroidism
- Autoimmune diseases, such as pemphigus, lupus, or vasculitis
- Polyps (fleshy growths inside the ear canal)
- Certain types of cancer
- Trauma to the ear
Symptoms and Diagnosis
Symptoms of ear infections in Shih Tzus can be subtle, but common signs include head shaking, scratching at the affected ear, dark discharge, odor, and redness and swelling of the ear canal.
Dogs may also exhibit pain, itchiness, crusting or scabs in the ears, and a foul odor emitting from the ears.
Here are some common symptoms of ear infections in Shih Tzus:
- Frequent Head Shaking
- Scratching or Pawing at Ears
- Redness and Swelling
- Odor
- Discharge
- Pain and Sensitivity
- Balance Issues
To diagnose an ear infection in your Shih Tzu, your veterinarian will take a detailed history, perform a thorough physical exam, and use an otoscope to examine the ear canals. They may also take a swab of the ear canals to perform an in-house cytological evaluation to identify the type of ear infection.
Symptoms
Symptoms of dog ear infections can be quite varied, but some common signs include head shaking, scratching at the affected ear, and dark discharge.
Head shaking is a common symptom, often accompanied by a head tilt. The affected ear may also have a foul odor or discharge.
Scratching at the ear is another sign, which can lead to crusting or scabs in the ears. Pain and discomfort are also common, causing the dog to exhibit behaviors like rubbing or pawing at the ears.
Some dogs may also experience aural hematoma, a blood accumulation in the ear pinnae. This can cause swelling and pain in the ear flap.
Dogs may show a range of symptoms, including redness, odor, itching/scratching, pain, shaking of the head, head tilt, discharge, and scabs or crusting around the ear flap.
Here are some common symptoms of dog ear infections:
- Head shaking
- Scratching at the affected ear
- Dark discharge
- Foul odor
- Redness and swelling
- Pain and discomfort
- Itching/scratching
- Crusting or scabs in the ears
- Aural hematoma (blood accumulation in the ear pinnae)
- Discharge from the ear canals
- Swelling of the ear flap
In severe cases, dogs may experience hearing loss, balance issues, or even a decrease in appetite.
How Chronic Diagnosed?
To diagnose chronic ear infections in dogs, your veterinarian will start by taking a detailed history of your dog's symptoms and medical history. They'll then perform a thorough physical exam, including an otoscopic examination of the ear canals.
An otoscope can help identify any masses, polyps, or growths within the ear canal. Your veterinarian will use this tool to get a closer look.
A swab of the ear canals is usually taken to perform an in-house cytological evaluation. This will help identify the type of ear infection, such as yeast, bacteria, or ear mites.
Types of Infections
Shih Tzus are prone to ear infections, and understanding the types of infections they can get is crucial for effective home treatment. Yeast infections are one of the most common types of ear infections in dogs, caused by an overgrowth of the naturally occurring fungus found on their skin and in their ears.
Yeast infections can be treated at home with regular cleaning and medicated cleansers. Bacterial infections, on the other hand, are caused by germs like Staphylococcus, Escherichia coli, and Klebsiella spp, which can overtake the ear and cause an infection. Regular cleaning and medicated cleansers can also help with bacterial infections.

Mite infestations occur when parasitic mites like Otodectes cynotis set up shop in your dog's ears, causing extreme itchiness and discomfort. These pesky creatures feed on the wax and oil in the ear, making regular cleaning and medicated cleansers a must for effective treatment.
Yeast vs Bacterial: Key Differences
Yeast infections in dogs can be tricky to spot, but they often have a distinct odor and darker brown discharge.
A sample of ear discharge is usually needed to determine the type of infection under a microscope.
Bacterial infections, on the other hand, tend to have a lighter brown or yellow color.
Most dogs with otitis externa have a yeast infection.
Infections of the middle and inner ear are usually bacterial.

Types of
Ear infections in dogs can be a real nuisance, but understanding the different types can help you identify the issue and find the right treatment.
There are three main types of ear infections in dogs, depending on the location of the infection. These include otitis externa, otitis media, and otitis interna.

Otitis externa is the most common type of ear infection, affecting the ear canal. It's often caused by exposure to the outside world, making it more prone to infection.
Otitis media and otitis interna affect the middle and inner ear, respectively. These infections can be more serious and require prompt veterinary attention.
In addition to these types of ear infections, there are also specific causes to consider. These include yeast infections, bacterial infections, and mite infestations.
Here's a breakdown of the most common types of ear infections:
- Yeast infections: These occur when the yeast population in the ear overgrows, causing inflammation and discomfort.
- Bacterial infections: Bacteria like Staphylococcus, Escherichia coli, and Klebsiella spp, and pseudomonas can overtake the ear and cause an infection.
- Mite infestations: Otodectes cynotis, a parasitic mite, can set up shop in your dog's ears, causing extreme itchiness and discomfort.
These types of ear infections can be acute or chronic, and treatment depends on the cause and severity of the infection.
Yeast
Yeast is a common culprit behind ear infections in dogs. It's a fungus that naturally lives in the ear, but when it overgrows, inflammation and discomfort occur.
Some breeds are more prone to yeast infections due to their ear shape and size. For example, dogs with long, floppy ears are more susceptible to trapped moisture, which can lead to yeast growth.
Hot and humid weather provides the perfect environment for yeast to thrive. This is why your vet may see more yeast infections in the summer months. Moisture and warmth combined with a lack of airflow in the ear canal can cause yeast to multiply rapidly.
Yeast infections can cause a range of symptoms, including brown, greasy discharge and itchiness. This can be uncomfortable for your dog and may lead to excessive scratching.
Here are some common causes of yeast ear infections in dogs:
- Trapped moisture, particularly in dogs with long floppy ears
- Antibiotics
- Immunodeficiency
- Too much bathing
- Yeast allergy
- Frequent swimming
- Exercise in humid environments
- Feeding your dog sugary snacks
- Not cleaning your dog's ears often enough
What Is an?
An ear infection is a common issue that affects many dogs, causing inflammation in the outer, middle, or inner ear. These infections can be caused by bacteria, yeast, or other irritants.
Some breeds are more prone to ear infections due to their ear structure. Basset Hounds and Cocker Spaniels are two breeds that are particularly at risk because their large, floppy ears create a warm and moist environment that's perfect for bacteria and yeast to thrive.
Dogs with droopy ears are especially susceptible to ear infections if they swim, as water can easily get trapped in their ears, leading to residual moisture and potential infection.
Treatment and Management
If your Shih Tzu has an ear infection, it's essential to get them treated by a vet to determine the underlying cause. Your vet will likely recommend a good ear cleaning to get treatment started.
Most dogs recover uneventfully from ear infections, but if your Shih Tzu is having frequent or chronic ear infections, your vet may suggest additional testing to rule out underlying causes. A diet change may be recommended if food allergies are suspected.
To manage your Shih Tzu's ear infection at home, you'll need to clean their ears regularly with a medicated cleanser, as recommended by your vet. The best treatment will depend on the underlying cause, which may include topical medications, oral antibiotics, or anti-inflammatory medications.
Here are some possible treatments for your Shih Tzu's yeast ear infection:
- Regularly cleaning your pup's ears at-home with a medicated cleanser
- Topical medications
- Oral antibiotics
- Anti-inflammatory medications
Treating Yeast Infections
The best treatment for your dog's yeast ear infection will depend on the underlying cause and may include a combination of treatments.
Your veterinarian will likely recommend regularly cleaning your pup's ears at-home with a medicated cleanser, as well as topical medications, oral antibiotics, or anti-inflammatory medications.
A good cleaning is essential to get treatment started off right, and your vet may perform this during your dog's appointment.
Topical medications can help clear up the infection, while oral antibiotics may be necessary if the infection is caused by bacteria.
Regular cleaning and medicated cleansers can help prevent future yeast infections by keeping the ear canal clean and dry.
Here are some common treatments for yeast ear infections:
- Medicated cleansers
- Topical medications
- Oral antibiotics
- Anti-inflammatory medications
It's essential to follow your veterinarian's recommendations and complete the full treatment course to ensure the infection is fully cleared up and to prevent future occurrences.
Recovery and Management
Recovery from ear infections in dogs is usually uneventful, but if your dog is experiencing frequent or chronic infections, your vet may recommend additional testing to identify any underlying causes.
Frequent ear infections can be a sign of an underlying issue, such as food allergies, which can be a common cause of infections.
Long-term management may include weekly ear cleaning to prevent future infections and reduce the risk of complications.
A diet change may also be recommended to address food allergies, which can be a contributing factor to chronic ear infections.
