Abstract
Brainstem auditory evoked response (BAER) is widely usedto detect deafness in human beings for
many years. It is increasingly being used for dogs. Canine studies with needle electrodes are documented
so far. Use of needle electrodes are painful and requires sedation or anesthesia. Disc electrodes allows nonsedation
assessments. However not much BAER studies are done in India. In this study a total of 6 dogs
were evaluated for brainstem auditory evoked response (BAER) using computerized BAER system with disc
electrodes used in human medical practice. Apparently healthy dogs were selected.The mean latency for I,
II, III, IV and waves V were 1.78±0.18, 2.68±0.11, 3.69±0.19, 4.71±0.08, and 5.73±0.20 ms in left ear, and
1.78±0.17, 2.79±0.07, 3.72±0.21, 4.67±0.14, and 5.77±0.09 ms in right ear, respectively. The mean inter
peak latencies for the I-III, III-V and I-V intervals were 1.89±0.32, 2.00±0.42, and 3.95±0.26 ms in left ear
and 1.92±0.25, 4.03±0.19, and 2.09±0.31 ms in right ear, respectively.
