Brainstem Auditory Evoked
Response (BAER)
This test records brain responses to click sounds delivered
to an ear. It does not require a behavioral response from
the animal, hence no chance of misinterpretation of a dog's
response. The test can be done quickly (with the appropriate
equipment), and will give a definitive record of each ear's
response to sound. The BAER is currently being used to
eliminate or reduce the incidence of genetic expression of
deafness from several breeds of dogs (i.e., Dalmatians,
English Setters). Since deafness is a genetic defect, and
since it appears essentially at 2-3 weeks of age, testing
the pup anytime after 5 weeks of age with the BAER has
become an excellent way to identify the auditory status of
individual dogs. This deafness trait has not been observed
to develop gradually in dogs, and does seem to be an
all-or-none situation for each ear.
Bilateral - deaf in both ears (i.e., totally deaf)
Unilateral - deaf in one ear (often called "unis")
Here are some basic steps that responsible Jack Russell
Terrier breeders can take to reduce deafness in Jack
Russells.
- BAER test all breeders and NEVER breed a totally deaf
or unilaterally deaf individual.
- BAER test ALL litters of puppies BEFORE they leave
your kennel to go to new homes.
- Avoid repeating a breeding that produces deafness.
- Responsible stud dog owners should never breed to a
bitch that has not been BAER tested.
- In most cases, do not place or keep a totally deaf
individual. It takes a VERY special person to raise and
train a deaf dog and the club does not recommend it
because of everything it involves. Fear biting is just one
of many problems. However, there are books on the subject
that can help an owner train a deaf terrier.
- Seek normal pet homes for unilaterally deaf puppies
but insist on them being spayed or neutered at the
earliest suitable age and NEVER provide pedigree and stud
certificate paperwork that is not clearly marked that the
individual is unilaterally deaf.
