Shih Tzus do not inherently have bad hearing, but they can experience hearing loss due to age, ear infections, or other health issues. Let’s explore the factors that can affect a Shih Tzu’s hearing, how to recognize signs of hearing loss, and ways to care for their ears to maintain good hearing health.
Shih Tzus are beloved for their charming personalities, luxurious coats, and affectionate nature. However, like all breeds, they can face certain health challenges, including hearing issues. Understanding the causes of hearing loss in Shih Tzus, recognizing the signs, and knowing how to care for their ears can help ensure your furry friend enjoys a healthy and happy life.
Hearing Range: Dogs have a broader hearing range than humans, capable of detecting sounds between 40 Hz to 60,000 Hz. This allows them to hear higher-pitched sounds that are inaudible to us.
Ear Structure: A dog’s ear consists of three parts: the outer ear, middle ear, and inner ear. Each part plays a crucial role in capturing and transmitting sound waves to the brain.
2. Hearing in Shih Tzus
Breed Characteristics: Shih Tzus do not have significant genetic predispositions to hearing loss. However, their long, floppy ears can make them more susceptible to ear infections, which can impact hearing.
Age-Related Hearing Loss: Like many breeds, Shih Tzus can experience age-related hearing loss (ARHL) as they get older. This type of hearing loss typically begins with a reduced ability to hear high-frequency sounds.
Causes of Hearing Loss in Shih Tzus
1. Age-Related Hearing Loss (ARHL)
Natural Aging Process: As Shih Tzus age, the structures within their ears can deteriorate, leading to gradual hearing loss. This is a common condition in senior dogs and is often irreversible.
Symptoms: Signs of ARHL include a lack of response to verbal commands, difficulty waking up, and increased startle responses when approached.
Susceptibility: Shih Tzus are prone to ear infections due to their long, floppy ears, which can trap moisture and debris. Chronic ear infections can lead to inflammation and damage to the ear structures, resulting in hearing loss.
Symptoms: Symptoms of ear infections include head shaking, scratching at the ears, redness, swelling, and discharge.
3. Congenital Deafness
Genetic Factors: While congenital deafness is rare in Shih Tzus, it can occur due to genetic factors. Puppies born with congenital deafness may show signs of hearing impairment from a young age.
Diagnosis: Congenital deafness can be diagnosed through specialized hearing tests, such as the Brainstem Auditory Evoked Response (BAER) test.
4. Environmental Factors
Noise Exposure: Prolonged exposure to loud noises can damage a dog’s hearing over time. This type of hearing loss is more common in dogs that live in noisy environments or are frequently exposed to loud sounds.
Trauma: Physical trauma to the head or ears can also result in hearing loss.
Recognizing Signs of Hearing Loss
1. Behavioral Changes
Lack of Response: One of the most common signs of hearing loss is a lack of response to verbal commands or familiar sounds. Your Shih Tzu may not come when called or may seem disinterested in their surroundings.
Increased Startle Response: Dogs with hearing loss may startle more easily when approached from behind or when touched unexpectedly.
2. Changes in Vocalization
Barking: Some dogs may bark more frequently or at inappropriate times due to their inability to hear environmental cues. Conversely, some dogs may become quieter as they lose their hearing.
3. Physical Symptoms
Ear Scratching and Head Shaking: Frequent scratching at the ears or shaking the head can indicate ear infections or discomfort. These behaviors should be investigated by a veterinarian.
4. Difficulty Waking Up
Deep Sleep: Dogs with hearing loss may sleep more deeply and be harder to wake up. They may not respond to noises that would typically rouse them.
Caring for Your Shih Tzu’s Ears
1. Regular Ear Cleaning
Cleaning Routine: Regular ear cleaning can help prevent ear infections and maintain good ear health. Use a veterinarian-recommended ear cleaner and gently clean the outer ear with a cotton ball or soft cloth.
Avoiding Damage: Never insert objects into your dog’s ear canal, as this can cause injury or push debris further into the ear.
Check for Symptoms: Regularly check your Shih Tzu’s ears for signs of infection, such as redness, swelling, discharge, or a foul odor. Early detection and treatment can prevent complications.
Veterinary Visits: Schedule regular veterinary check-ups to monitor your dog’s ear health and address any concerns promptly.
3. Protecting Against Noise
Noise Reduction: Minimize your dog’s exposure to loud noises, such as fireworks, loud music, or construction sounds. Consider using noise-canceling devices or creating a quiet space for your dog during noisy events.
Ear Protection: In situations where loud noises are unavoidable, consider using ear protection designed for dogs.
4. Training with Hand Signals
Hand Signal Training: Training your Shih Tzu to respond to hand signals can be beneficial, especially if they experience hearing loss. Start by pairing verbal commands with hand signals and gradually phase out the verbal cues.
Consistency: Consistency is key when training with hand signals. Use the same signals for specific commands to avoid confusion.
Health and Veterinary Care
1. Regular Check-Ups
Veterinary Visits: Regular veterinary visits are essential for monitoring your Shih Tzu’s overall health, including their hearing. Your vet can perform ear exams and recommend treatments if necessary.
Preventive Care: Preventive care, such as vaccinations and parasite control, can help maintain your dog’s health and prevent conditions that could impact their hearing.
2. Specialized Hearing Tests
BAER Test: The Brainstem Auditory Evoked Response (BAER) test is a specialized hearing test that can diagnose hearing loss in dogs. This test measures the electrical activity in the brain in response to sound and can determine the extent of hearing loss.
Routine Screening: Routine hearing screenings can help detect hearing loss early and allow for timely intervention.
3. Managing Hearing Loss
Adapting to Changes: If your Shih Tzu experiences hearing loss, it’s important to adapt to their changing needs. Use visual cues, maintain a consistent routine, and provide extra support and reassurance.
Communication: Communicate with your dog using hand signals, vibrations, and other non-verbal cues to maintain a strong bond and ensure their safety.
Shih Tzus do not inherently have bad hearing, but they can experience hearing loss due to age, ear infections, or other health issues. By understanding the causes of hearing loss, recognizing the signs, and providing proper ear care, you can help maintain your Shih Tzu’s hearing health and overall well-being. Regular veterinary check-ups, preventive care, and training with hand signals can make a significant difference in managing hearing loss and ensuring a happy, healthy life for your furry friend.
