Deafness In Dogs

Deafness In Dogs: What Breed Of Dog Is Often Deaf?

The deafness in dogs is caused by different causes. There are several types of deafness in dogs. Some of them are inherited, while others are due to other factors such as trauma or infection. These types of deafness may cause some symptoms and signs only at certain times or not at all. For example, if your dog was born with no hearing at all, it will never develop any signs or symptoms of deafness. However, if he/she gets shot during hunting season then the deafness may manifest itself later on.

Some dogs have been known to go deaf overnight without even being touched by anything. They become completely silent and they don’t react when their owners approach them. Other dogs show signs of hearing loss after getting hit by bullets but before going blind from blood loss.

There are many reasons why deafness occurs in dogs. One of the most common ones is due to a genetic defect called spina bifida. Another reason could be due to trauma or infection. Infection can occur through bite wounds, bites from other animals, infections in the mouth or throat, and from parasites like tapeworms.

Other causes of deafness include tumors (brain tumors), tumors (heart tumors) and disorders of the inner ears (otolith dysfunction). Viruses, specifically the degenerative ones, have been known to attack the nerves of the inner ear and damage hearing as well. Other causes can be meningitis, exposure to loud noises, parasites in the ears, low blood sugar, excess calcium in the system, poisoning and some types of medications.

There are also non-medical reasons for why dogs become deaf such as age-related hearing loss and congenital deafness. Age-related hearing loss can occur in dogs as young as four years old. Congenital deafness is a defect that is present at birth.

Deafness In Dogs: What Are The Symptoms?

Some signs and symptoms of deafness in dogs are very clear. These include:

1. Difficulty hearing horns honking, alarms ringing and telephones ringing.

2. Difficulty responding to verbal commands.

3. Difficulty responding to other loud noises.

4. Does not react to the noises of children playing or other loud activities.

Other deaf dogs may not always show these signs. They learn to compensate quite well for their hearing loss. Other signs your dog may show are scratching its ears a lot, tilting its head when you call its name, and not responding to a knock at the door. Sometimes a wagging tail does not necessarily mean that the dog can hear.

It could mean that it feels air movement or that it sees your waving hand.

Deafness In Dogs: How Is It Diagnosed?

In order to get a proper diagnosis of deafness in dogs, many tests must be performed. The veterinarian may do a complete examination including a check up of the ears. A common test for hearing is the ability to respond to a sharp noise (clicking the tongue, snapping the fingers, dropping a pencil on the floor). The animal should respond to this. A vibrating device can also be used to test hearing. Anesthesia may be required in order for the veterinarian to inspect the ears internally. This is especially true for wax buildup. These tests should reveal any physical problems that cause deafness.

Once medical problems have been ruled out, the veterinarian may perform a diagnostic test of hearing. This can be done by placing a vibrating device under water and seeing if the dog reacts to it. This is to rule out the possibility that the problem is excessive earwax or an infection. If that test is passed, then it is assumed that the dog’s hearing loss is due to noise trauma or some other form of age-related hearing loss.

Deafness In Dogs: Treatment

The treatment for deafness will vary depending upon what has caused it. If the dog is deaf due to age-related hearing loss, there really isn’t much that can be done other than to make sure it does not get startled by unexpected noises.

If the dog is deaf due to excessive earwax, an antibiotic such as Clotrimazole will be used to treat the infection. This will usually be given for about a week.

Deafness due to infection or noise trauma usually involves surgery. The veterinarian will cut into the ear and remove the inner ear tissue that is damaged. This tissue will be sent to a lab to be biopsied to determine the exact cause of the hearing loss. After this procedure, the dog’s hearing should gradually return.

As you can see, there are several potential causes for deafness in dogs and each case must be handled accordingly. If you notice that your dog is not responding to loud noises, contact your veterinarian right away. Hearing loss can be temporary or permanent and the sooner it is addressed, the more successful any treatment will be.
