Deafness in animals can occur as either unilateral (one ear affected) or bilateral (both ears affected). This occurrence of either type of deafness seems to be relatively the same in both mixed-breed animals and pure-breed animals. [5] Research has found a significant association between deafness in dogs and the pigment genes piebald and merle ...
The white-spotted cat hisses at the dog, the solid-white deaf cat dozes unaware of the barking. Congenital sensorineural deafness occurs commonly in domestic cats with a white coat. It is a congenital deafness caused by a degeneration of the inner ear. [1] Deafness is far more common in white cats than in those with other coat colours.
As healthy ferrets have poor hearing, deafness may only be detected by lack of reaction to loud noises. As this is an inherited disorder, affected animals should not be used for breeding. A study of the correlation between coat variations and deafness in European ferrets found, "All (n=27) panda, American panda, and blaze ferrets were deaf." [59]
In some breeds of cats congenital sensorineural deafness is very common, with most white cats (but not albinos) being affected, particularly if they also have blue eyes. [1] The gene responsible for this defect is the KIT gene and the disease is studied in the hope that it may shed light on the causes of hereditary deafness in humans. [8]
Cole, the deaf therapy dog, works alongside his owner at the Dr. Mennies School in the South Jersey school district. This precious Pit Bull is deaf and in a recent social media video, this may not ...
A US study found 25.7% of Dalmatians to be deaf in one or both ears. This study found that the evidence of a single gene being responsible for deafness to be unlikely. [21] Researchers now know deafness in albino and piebald animals is caused by the absence of mature melanocytes in the inner ear. [22] This may affect one or both ears.
Deaf Dogs Evie’s deafness is from birth. White dogs have a far higher likelihood of being born death due to the way pigmentation affects the development of their ears.
It is a common misconception that all white cats with blue eyes are deaf. [14] This is not true, as there are many blue-eyed cats with perfect hearing. However, white cats with blue eyes do have slightly higher probability of genetic deafness than white cats of other eye colors. [15]
