Protocol and Instructions for the BAER Tester 

Dogs must be evaluated by brainsterm auditory evoked response (BAER). Bone stimulation transducer will be used in addition when conduction deafness is suspected

The examiner must be a person recognized by the GDC to have expertise in the use of both systems of testing and is agreeable to using the current GDC protocol. A list of acceptable testers is available from GDC.

BAER testing is done on canines at least 35 days old 
A signal sound presure level between 70 and 105 DB is used to obtain a response with peaks I through V judged present at their appropriate latencies. 
Insert earphones will be used 
Chenical restraint is optional. 
The work is done in such a manner that movement will not cause an artifact that could be mistaken for a repopnse to a stimulus. 
At least 200 clicks will be used to obtain the response 
A masking tone is not considered necessary if recordings are made with electrodes positioned along the midline and in the ipsilateral mastoid region; a masking tone is necessaary if the electodes are placed along the midline at the vertex and at T-1. 
Under appropriate circumstances when an ear tests as deaf using air-conducted stimuli and the possibility of conduction deafness exists (chronic otitis, excess ear wax accumulation), repeat testing with a bone stimulation transducer is recommended. 
A printed copy of the BAER Test tracing will be provided to the owner and the GDC. 

By certifying that a dog has BAER BILATERAL hearing, the professional performing the test is making this statement in accordance with their best clincal judgment. The GDC has a system for appeal if there is significant reason to question the test results.
For GDC registration please mail:
  1. this GDC application/release form, signed by owner and the Tester: 
  2. a copy of the BAER test tracing; 
  3. a check for the appropriate amount according to the attached fee schedule.
