Some breeders may be confused about
the process of completing OFA and CERF certifications for their
Bichons, which certainly can be complicated. After reading all the
material on the OFA web site
www.offa.org and emailing them with questions, I hope this
summary will help.
Breeders need to share health data
with other breeders to facilitate wise breeding decisions, which can
be accomplished by releasing the information to the public, i.e. it
will be posted on the OFA web site. This site contains not only
information and statistics about all of the diseases that can
achieve an OFA certification, but also CERF and OFA reports on each
dog and its relatives. To find a particular Bichon or breeder, just
click on “search OFA records”. Many breeders routinely access the
OFA web site when searching for a mate for their dog. Also, some
wise pet buyers are consulting this web site to find reputable
breeders that complete health clearances prior to breeding. If you
do not submit the OFA or CERF forms to the appropriate certifying
body, there will be no report on your Bichon on the OFA web site.
CERF:
Genetic cataracts continue to
plague Bichons as the #5 health issue in the breed. To
obtain CERF certification, you need to find a canine ophthalmologist
who will provide the forms at the clinic. You will need to complete
the form with data on the dog from its AKC registration paper and
the dog needs a microchip or tattoo for identification. Dr. Gelatt,
who is researching Bichon cataracts, recommends the initial CERF
exam at the age of 1 year, and annually thereafter since CERF
certification is only valid for one year and the Bichon
cataracts can develop anytime from the age of 1 to 8 years. Once
the form and exam is completed, you receive one copy, the
ophthalmologist retains one copy, and one copy is sent to CERF for
research data whether the dog’s eyes are normal or abnormal. CERF
sends data to me at the end of each year that contains the incidence
of specific eye diseases in Bichons, but no names of dogs or
kennels, so the data is anonymous.
If your Bichon’s eyes are normal
and you chose to send your copy to CERF, the data will appear on the
OFA web site as soon as the dog has some type of OFA certification
completed. If you do not complete any OFA certifications on your
dog, the CERF report will never appear on the OFA web site because
OFA requires a database to be established on that particular dog
prior to importing data from CERF. If your Bichon fails the CERF
exam and you send your copy of the completed form to CERF, they will
return it to you with a refund of the fee. Instead, you can send
the form to OFA (their mailing address is on their web site) with a
note that you want the results posted on their web site to share
with other breeders.
OFA HIPS, ELBOWS:
Hip and elbow dysplasia are rare
diseases in Bichons, but do exist and are very debilitating. To
obtain OFA certification of hips and elbows you should find a
veterinarian who is very proficient at achieving the proper xray, or
utilize an orthopedic specialist at a university veterinary clinic.
Your Bichon must be at least 2 years of age for a permanent hip or
elbow certification, but preliminary certifications can be completed
if your dog is at least one year of age. If you plan to complete
both OFA certifications, there is a price break if they are
completed simultaneously. OFA recommends sedation to obtain an
optimal xray, but accepts precise xray films without sedation.
Personally, I prefer no sedation because of the health risks of
anesthesia and the compliance of Bichons.
If your dog passes the OFA
certification process as being free of hip dysplasia, then the hips
are rated as fair, good, or excellent. A rating of fair does not
mean your dog has hip dysplasia, which is a disease that the dog
either has or does not have, like pregnancy—you either are pregnant
or not. Breeding a Bichon with fair hips is the breeder’s option,
however consider only breeding that dog to a dog with hips rated
either excellent or good by OFA.
OFA PATELLAS (KNEES):
Patellar luxation, a kneecap
that pops in and out of place, can be evident at the age of 8 weeks
and causes lameness and pain. Its incidence in Bichons has become
pervasive, climbing from #9 in 1992 to #3. Patella certification
only requires an exam by a veterinarian, not a specialist.
Instructions on the procedure are contained in the application
form. Your dog must be at least 1 year of age, and bitches must not
be in season or pregnant to avoid the effects of hormone
fluctuations. Patellar luxation can develop anytime before or after
one year of age, so BFCA encourages you to do subsequent exams
yearly. Puppies should be examined at the age of 6-8 weeks for
patellar luxation prior to sale, but cannot be certified until 1
year of age.
OFA CARDIAC:
The prevalence of heart diseases in
Bichons has escalated from #11 to #7. To obtain cardiac OFA
certification, the optimal method is to choose a cardiologist at a
university veterinary clinic, the second choice is an internist, but
a veterinarian can also perform the exam if they have received
advanced training in congenital heart disease and detecting soft
murmurs. The exam requires the vet to listen to heart sounds and
examine your dog for signs of heart disease such as weak pulses,
color changes in the skin, and an abnormal heart rate or rhythm.
This certification can be obtained at the age of 1 year.
OFA CONGENITAL DEAFNESS:
According to OFA “Congenital
deafness has been reported for approximately 80 breeds, with the
list growing at a regular rate”. Bichons are included in this list,
most of which are dogs with light colored coats that may indicate a
pigment-associated genetic link. Dogs that have unilateral deafness
are at as much risk to pass this to offspring as dogs with bilateral
deafness. However, a
dog with unilateral deafness shows no signs of hearing loss (since
the other ear is functional) but DOES pass the gene, indicating the
need to test dogs that appear to have adequate hearing.
The test for deafness is the
Brainstem Auditory Evoked Response (BAER), which can be performed by
preferably a veterinary neurologist or an experienced
veterinarians/audiologists at the age of at least 35 days, with
chemical restraint optional. Three of my dogs, the only Bichons
ever BAER certified, completed this test without problems. It
involves attaching tiny electrodes to the scalp and placing
earphones in the ears, all attached to a monitor that displays a
waveform with each sound introduced to the dog. The dog must lie
still to avoid artifact from movement, which was easily accomplished
on my adult Bichons, but may be a challenge for puppies.
OFA THYROID:
This certification is accomplished
by sending a blood sample to an approved laboratory that tests the
dog for hypothyroidism, most commonly caused by autoimmune
thyroiditis. The onset of the disease is variable, most commonly at
2-5 years of age. However, the blood test measures autoantibodies
for this disease that are most often present in the blood by the age
of 3-4 years. Testing at 1 year of age and retesting yearly is
recommended, and bitches must not be in season or pregnant to avoid
the effects of hormone fluctuations. Hypothyroid disease is rare in
Bichons.
OFA Legg-Calve-Perthes Disease (LCPD):
LCPD is another hip disease that can be included in OFA
certifications, free of charge as long as the dog’s hips have been
OFA certified. The same xray can be used to evaluate for hip
dysplasia and LCPD, however a dog that has LCPD will not pass OFA
certification of the hips. The LCPD form, which can be downloaded
from the OFA web site, is submitted either with the hip OFA form or
separately. This hereditary disease is more serious and more common
in Bichons than hip dysplasia. The femoral head that sits inside
the hip socket becomes necrotic from lack of blood supply, which
results in degeneration of the bone. If your dog receives an OFA
hip certificate, it does not have this disease. If your dog does
not have OFA hip certification you can obtain LCPD certification
after the age of 1 year by submitting an xray and the LCPD form to
OFA with the required fee. You can read more about this disease at
http://www.bichonhealth.org/HealthInfo/LeggCalvesPerthes.asp.
FORMS:
The forms for OFA certifications
can be downloaded from the OFA web site by clicking on “OFA
applications”. On these forms there is a box where you can sign to
authorize the abnormal results to be published:
Authorization to Release Abnormal Results
I hereby authorize the OFA to release the results of its
radiographic evaluation of the animal described on this
application to the public if the results are
abnormal_______________ (initials of registered
owner).____________
If you chose not to sign this area,
and later you wish to publish abnormal results, there is a form you
can download from the OFA web site by clicking on “open database
authorization”. If you chose to publish abnormal results, the
veterinarian must send the xray and a copy of the form to OFA.
If you do not chose to publish abnormal results, please assure
that the vet sends the xrays and forms to OFA so the data can be
utilized for research, which remains anonymous. Data
obtained from the OFA reflects the incidence of these diseases in
Bichons and helps us determine research priorities. If abnormal
xrays and forms are not sent to OFA, showing a false low incidence
for that particular disease will skew the data.
OFA and VPI:
OFA recommends that all dogs
examined for OFA certifications have their identity verified by the
examining veterinarian, evidenced by an addition to their new forms
this year—the area where the veterinarian indicates whether they
verified the identification of the dog via the tattoo or microchip:
If the examining vet has the old
OFA forms without this VPI (verification of permanent
identification) area added, a separate VPI form can be submitted
with the old OFA form, which can be downloaded from the OFA web
site:
http://www.offa.org/vpiapp_bw.pdf.
As of January 1, 2008 AKC will no
longer accept OFA data from hip and elbow certifications into their
registry unless the VPI requirements are met. This means that your
Bichon must have permanent identification (tattoo or microchip)
verified by the examining vet, indicated in the VPI area of the hip
or elbow OFA form or on a separate VPI form, in order for the OFA
numbers for hips and elbows to appear on official AKC pedigrees and
registration papers. If you have any doubts about the identity of a
dog certified, refer to the suffixes of the OFA numbers for a dog
that is listed on the OFA web site:
NOPI = number issued
to a dog without any permanent ID
PI = number issued to
a dog WITH permanent ID, but the ID was not verified and signed off by the examining
veterinarian
VPI = number issued
to a dog WITH permanent ID, and the ID was verified by the vet,
and these results go to the AKC
(as of 1/1/08)
