Reasons for hearing loss in dogs
Posted on October 07 2018
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.
The dog's hearing abilities are far superior to those of humans. Our 4-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 him because many actions depend on his daily life. Preventing ailments by regularly examining and cleaning your ears helps 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. The bull terriers , Mastiffs Argentine , Australian Shepherds and Dalmatians are included. 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 ...
In most cases, hearing loss in puppies is 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 his hearing by scrutinizing his reaction to sound stimulation , such as clapping his 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 his ears .
Finally, his behavior towards his mother and the other litter puppies provide as many indications as to his hearing ability: if he continues to bite them despite their cries, this may mean that he do not hear these. To be clear, it's up to the veterinarian to turn around. It may then suggest to subject the puppy to auditory and neurological tests to detect a possible deafness.
... and in adultsWhen due to illness or aging , hearing loss can be manifested in different ways in adult or older dogs . It is sometimes enough to observe the attitude and the reactions of the dog in various situations to realize partial or total deafness.
You can, for example, note how he responds to calls and orders , if he obeys after looking at his master to understand what he wants from him. He may often seem surprised when approaching him or when someone approaches him without having been in his visual field. Its lack of reaction to surrounding noises (horns, barking of its congeners, etc.) is also a sign that may suggest a hearing loss.
