Dog breeds with tendency to congenital deafness
Deafness in dogs also has some correlation with whiteness in the dog's coat, but to a much lesser extent than with cats. The particular breed plays a greater role in the chance of a dog's having deafness. There is also a far larger number of distinct dog breeds (78) identified as having consistently higher numbers of congenitally deaf individuals than in other breeds:
|(After George M. Strain)|
Those breeds listed in bold have relatively high prevalences of congenital (hereditary) deafness.
Dalmatians have the highest proven incidence of all, with 8% being born deaf in both ears and up to 22% deaf in one ear. English setters are second, averaging 2.3% bilaterally deaf; third are Australian cattle dogs at 2.1% bilaterally deaf; fourth place is split between bull terriers and English cocker spaniels at 1% each. Each of these breeds also has a higher occurrence of deafness in just one ear.
Jack Russell terriers have tested out with a 10.6% bilaterally deaf rate (plus 8.5% unilaterally deaf), and the Catohoula leopard dog has been tested to have an incredible 41.7% bilaterally deaf rate (plus 27.1% unilaterally deaf). However, it must be pointed out that the numbers tested in each of those two breeds are too low to be statistically significant (less than 50 individuals were tested), and those figures should not be trusted until a larger number of animals in those two breeds can be tested for a better statistical sampling.
