CONGENITAL DEAFNESS in DALMATIANS

 

Included on this page are references for more information on inherited congenital deafness in Dalmatians, BAER testing, and BAER testing locations in Canada.  The information is a starting point, if you have questions, or suggestions for other resources that you feel should be included, contact the club dalmatianclubcanada@gmail.com 

 

Inherited congenital deafness is a problem in the Dalmatian breed.  While it has been found present in over 80 breeds, the disorder in the Dalmatian is associated with the piebald gene.  While the exact genetic transmission is not known, there are a lot of resources about this subject, further information can be found at:

BAER TESTING

 

BAER (brainstem auditory evoked response) testing detects electrical activity in the auditory pathways to the brain.  The test itself is non-invasive and does not require sedation.  The test can be performed on puppies starting at 35 days but many breeders wait until 6 weeks to ensure developmental changes have occurred.  If you are buying a puppy, the breeder should supply copies of the printouts of the waveforms from both ears.
