Deafness in Dogs

Deafness can manifest as temporary, partial, or complete hearing loss in one or both ears. Causes of deafness in dogs include congenital disorders, infection, trauma, old age, and obstruction. Congenital deafness is more common in some dog breeds and in dogs with white or blue-grey fur. Deafness due to genetic predisposition, aging, and trauma is highly likely to be permanent and has no cure. However, some deafness that develops later due to blockage or infection may be temporary and most are treatable.

If you suspect your dog has a hearing problem, it is recommended that you consult a veterinarian without delay. Because in some cases, hearing loss starts mildly and progresses to deafness. Excessive earwax buildup, infection, injury, polyps, tumors, foreign objects, or other blockages in the dog's ear are easier to treat when diagnosed early, and in this way, the condition can be treated before any hearing loss occurs in the dog.

Symptoms of Hearing Loss in Dogs

Hearing loss can lead to various symptoms. One or more of these symptoms may appear at the same time. If symptoms of hearing loss or deafness appear, the dog should be taken to a veterinarian for examination without delay. The main symptom of hearing loss is unresponsiveness to various sounds. These sounds include:

• Sesli oyuncaklar,
• Clapping,
• Doorbell;
• Seslenme
• Other dogs barking, etc. Dogs with hearing problems are difficult to wake up, can be easily frightened, and tend to bark excessively.

Types of Hearing Loss in Dogs

There are different types of hearing loss in dogs. The underlying cause of hearing loss leads to different treatment approaches.

Congenital deafness is usually caused by genetic or congenital anomalies. The failure of the dog's ear or nervous system to develop correctly in the womb can cause congenital deafness.

Acquired deafness, on the other hand, is a type of hearing loss that develops as a result of problems that occur later in life, such as trauma, infection, ear canal blockage, or geriatric nerve degeneration, even though the dog has a normal sense of hearing from birth. Acquired deafness is completely curable in some cases.

Conductive deafness is a rare type of hearing loss. It occurs as a result of problems in the transmission of sound heard from the outside to the nerves in the inner ear.

Another type of hearing loss is sensorineural hearing loss. Hearing loss occurs when nerve receptors fail to transmit signals from the ear to the brain's hearing center. Causes of Hearing Loss in Dogs The causes of hearing loss can vary depending on the breed. Congenital deafness in the ear or nervous system is usually due to a genetic problem or abnormal development. Hearing loss is more common in some dog breeds and in dogs with certain coat colors. Hearing problems are more common among dogs with white or bluish-gray fur on their ears and heads. Other causes of hearing loss include:

Other causes of hearing loss include:

• Aging,
• Constant exposure to loud noise,
• Obstruction,
• Yaralanma,
• Kulak enfeksiyonu,
• Inflammation or tumor in the ear or Eustachian tube,
• Exposure to heavy metals such as arsenic, lead, or mercury,
• Medications used in the treatment of certain diseases can be listed.

Diagnosis and Treatment Methods

When you suspect your dog has hearing loss, you can test it by standing behind it and making sounds like clapping. Partial or unilateral hearing loss may be more difficult to detect. For this, you can test both ears of your dog using softer sounds or snap your fingers near the ears.

To diagnose hearing loss, a veterinarian performs a hearing test and physical examination. During the examination, the veterinarian also checks for earwax or foreign object blockages in the dog's ears. If an ear infection is suspected, a sample is taken from the ear to plan the treatment.

Treatment is usually not possible for congenital or age-related hearing loss. The chance of treatment is higher if the structural defect is in the outer or middle ear. However, the inner ear contains extremely delicate tissues. Congenital disorders seen in these tissues cannot be treated. Hearing loss caused by blockages resulting from a foreign object or earwax is the easiest type of hearing loss to treat. Sometimes even excessive hair growth inside a dog's ear can lead to hearing loss. In the treatment of hearing loss resulting from an ear infection, antibiotic treatment or anti-inflammatory drug treatment is started depending on the severity of the infection. In the treatment of hearing loss resulting from a tumor or polyp in the ear, surgical removal may be necessary depending on the condition of the mass.
