Partial or complete deafness, affecting one or both ears, can occur in dogs for a variety of reasons. Prevention and treatment are possible in most cases.
➥Detecting hearing loss in puppies
The hearing abilities of the dog are far superior to those of humans. Our four-legged friends are indeed able to hear sounds ranging from 67 (low sounds) to 45000 Hertz (treble), while the man can only hear between 20 and 20000 Hertz.
With flair, hearing is one of the most developed senses in dogs. Preserving the faculties is vital for it because many actions depend on its daily life. Preventing ailments by regularly examining and cleaning your ears helps to reduce the risk of hearing loss. There are also curative measures whose effectiveness is increased when they are applied quickly and after early detection.
Hearing loss in dogs can be partial, total, unilateral (affecting only one ear) or bilateral (affecting both ears). The origin of the dysfunction is, for its part, either congenital or due to disease or aging.
The puppy can be born with partial or complete deafness. It can also come into the world and grow with correct hearing abilities, but see these decline over the years.
Some breeds have predispositions to deafness. Bull Terriers, Argentine Dogs, Australian Shepherds, and Dalmatians are among them. It is estimated, for example, that 5% of Dalmatians suffer from bilateral deafness and 15% have unilateral deafness.
Among the diseases responsible for hearing loss, chronic ear infections are among the conditions that are blacklisted. They can be treated with medical treatments or surgery.
➥Detecting hearing loss in puppies …
The loss of hearing in puppies is, in the majority of cases, a hereditary anomaly. It can be detected early, but not before 3 weeks, because the young animal does not clearly perceive all sounds until this age.
After this time, it is possible to gauge its hearing by scrutinizing its reaction to sound stimulation, such as clapping its hands or shake a bunch of keys when looking elsewhere. Besides the attitude he displays when hearing these sounds, it is interesting to observe the mobility of its ears.
Finally, its behavior towards itsmother and other litter puppies provide as many indications as to its hearing ability: if it continues to bite them despite their cries, this may mean that he does not hear these. To be clear, it’s up to the veterinarian to turn around. It may then suggest subjecting the puppy to auditory and neurological tests to detect possible deafness.
➥… and in adults
When due to illness or aging, hearing loss can occur in different ways in adult and older dogs. It is sometimes enough to observe the attitude and reactions of the dog in various situations to realize partial or total deafness.
You can, for example, note how it responds to calls and orders if it obeys after watching its master understand what he wants from it. He may often seem surprised when approaching it or when someone approaches it without having been in its visual field. Its lack of reaction to surrounding noise (horns, the barking of its congeners, etc.) is also a sign that may suggest a hearing loss.
