At first you may not notice that your Great Dane is losing its hearing. Nevertheless, deafness in older Great Danes is quite common. Unfortunately, hearing loss is usually irreparable is caused naturally (rather than by sickness.).

A partial or complete loss of hearing.

Deafness is defined by partial or complete hearing loss. Levels of hearing impairment vary from a mild but important loss of sensitivity to a total loss of hearing. Older adults suffer most often from hearing loss. Age-related hearing loss affects 30 to 35 percent of the population between the ages of 65 and 75 years, and 40 percent of the population over the age of 75. The most common cause of hearing loss in children is otitis media, a disorder that affects predominantly infants and young children. A substantial number of hearing impairments are caused by environmental factors such as noise, drugs, and toxins. Many sensorineural hearing losses result from a genetic predisposition.

Causes can be hereditary, as well as other factors, including inner ear disease. Contact your vet, who will check the ears for wax, infection, tumours or parasites. If deafness is permanent, replace voice commands with eye contact and hand signals.

An individual who is totally deaf is unable to hear with or without the use of a hearing aid, whereas a person who is partially deaf may be able to hear with the help of a hearing aid. Deafness can be genetic or also acquired through disease, most commonly from meningitis in the child or rubella in the woman during pregnancy.
