I have been involved with the Fila Brasileiro Breed for almost 20 years now. I got my first
Fila Brasileiro in
November 1988. One of the things that the breeder I bought from warned me to
do was to OFA (Orthopedic Foundation for Animals) my dog's hips.
I was told that it was advisable to prelim ie., x-ray and get a preliminary
report around one year of age, although at that time you could prelim them
after four months of age. Where this comes in to play is if you are showing
your pup. By preliming it, you could find out if your show prospect was
worth the money you would be investing in it by showing.
OFA does not give a permanent certification until your dog is at least 24
months old. You do not want to prelim or have your female dog x-rayed if she
is close to her heat cycle or in it, as that can change the results. (As a breeder,
that is why I changed my Hip/Elbow guarantee to 27 months instead of 24
months, since that gives yhe owner of the female three months after the 24
months, should she be in heat, to get her x-rayed and certified).
The first Filas were OFA evaluated in 1986. There were two evaluated and
both passed. We assumed we had no dysplasia problem in the breed. In 1987
there were seven evaluated, of which three were dysplastic. (“Houston, we
have a problem.")
That's 42.9% that were not certified as hip dysplasia free.
The next year, 1988, only 14.3% were dysplastic. This was
much better, but it still left us with a 19.1% average of hip dysplasia in
the breed for each of the three years. In 1989, 33.3% of the Filas were
dysplastic!
In 22 years now, OFA shows an average of 29.3% of the 583 Filas evaluated
were dysplastic. But this is a false assumption, since there were the early
years when only one or two were evaluated. Last year 44.4% of the Filas
evaluated were dysplastic, which is still much higher than the 22 year
average of 29.3% shown on the OFA website.
It wasn't until 1990 that the first fila was evaluated for elbow dysplasia
and was certified. In 1991 there were two evaluated and only one passed, so
there was a 50% elbow dysplasia rate.
In 18 years there have been 166 Filas
evaluated for elbow dysplasia. OFA shows a yearly average of 23.5% elbow
dysplasia over this 18 year period, but in 2006, 40% of the Filas evaluated
for elbows were dysplastic, and last year, 50% were dysplastic.
Since 1988 I have used the same veterinarian for the whole time I have had
Filas. He and I are beginning to believe that elbow dysplasia may be a
bigger problem in our breed than hip dysplasia according to the database
that we have.
Until we get more owners
and breeders preliming or certifying their dogs, we will not know the extent
of the hip/elbow dysplasia problem in our breed. If we can build the
database by people OFA-ing their dogs it will give us a much better idea of
how extensive hip and elbow dysplasia really are in our Filas. Not only
that, but people will be able to look up a dog in the OFA database and know
which dogs in it's pedigree have been certified.
There is another organization, PennHip, that uses a different technique to
evaluate a dog's hips for hip dysplasia. Unfortunately they don't evaluate
for elbow dysplasia, so if you use PennHip, it is also advisable to have
your veterinarian submit x-rays of the dog's elbows to OFA so that you will
know if their are problems with any of the dog's four limbs. Why do just
half of the dog, especially since a Fila's front legs are shorter and carry
more of it's body weight?
In February 2005, I decided that i would run a small test of the two
organizations, OFA and PennHip. I took seven dogs to the vet over a two day
period. I
had the vet insert an Avid Microchip into each of the dogs to document each
dog's identity. The vet first placed the dog in a foam form to do the
PennHip evaluation so that each dog was positioned the same. The vet did the
PennHip x-ray first, then the x-ray for OFA. He made a copy for me and one
for his records.
Then he did the x-rays for the dogs' elbows.
He then submitted the x-rays to each organization.
PennHip's results came first. Two of the seven dogs were dysplastic. Two
weeks later, I got the OFA results. They had determined that four of the
seven dogs were dysplastic. OFA was tougher on my dogs than PennHip. From
that time forward I have not used PennHip since it seemed a waste of money
doing the PennHip vs OFA, plus I would have to submit elbow x-rays to OFA
anyway.
A lot of people think that you
only need to OFA or PennHip your dog if you're going to be showing it. That
is not a fair assumption. A pet Fila needs to e evaluated just as much as a
show dog. Why?
Wouldn't you give your dog a different
lifestyle if you knew it had bad hips or elbows? Would you allow your Fila
to run up and down the stairs if you knew it was hurting your dog? Remember,
the Fila has a great tolerance for pain and wants to please you, so he/she
will do what they can to make you happy, even though it may be hurting while
doing it. Also, if you knew that there was a problem, you could do
preventative medications and maintenance to give your dog a longer, more
comfortable life.
I actually knew one breeder who said that
only show dogs get hip or elbow dysplasia. (Thank goodness she is no longer
involved with Filas)
The worst case of hip dysplasia that I have had was a male pup I bought. He
had moderate hip dysplasia in both legs. He bunny-hopped when he ran and he
would not jump up against me or the fence since it hurt for him to do that.
With their tolerance for pain, you don't usually see this behavior.
I prelimed him at around a year and it showed moderate hip
dysplasia in both hips. A friend of mine had his sister. When she found out
my results, she had her female prelimed. She not only had moderate hip
dysplasia in both legs, the same as mine, but both of her elbows also failed
OFA - all four legs were bad. She will not be able to have surgery to
correct one ofthe legs since the others are not strong enough to support her
during recovery. When her quality of life is suffering, she will be put
down.
The breeder admitted later that the three
pups sold as show quality were all dysplastic and the two sold as pets were
never checked. What is seldom mentioned is the fact that the parents were
closely bred, as the brother of the mother was the father of the father. It's
also a known fact that this type of breeding either brings out the best of
the best genes or the worst of the worst, with the doubling up of family
genes. This litter was the worst of the worst for dysplasia.
I have had 18 filas x-rayed by my local vet and certified by OFA (one was a
co-ownership). He misjudged on three and said it wasn't worth sending in the
x-rays. Fortunately, i sent them in anyway and they passed. Had i taken his
word for it, they would not have been in my breeding program.
Of the last six that I had prelimed, five
passed while one was borderline and new x-rays should be resubmitted in six
months. My vet commented that I was seeing a lot less dysplasia in my
controlled breeding program of only using dogs who have been OFA certified
or prelimed.
Some of the breeders will tell you they read
the x-rays themselves or their local vet reads them. Filas's hips and elbows
are different from most breeds. It takes a Certified Radiologist to read
them correctly. What's good is the fact that the OFA Radiologists have
already read over 583 Fila hip x-rays and over 166 Fila elbow x-rays, so
they are used to the Fila's hip and elbow x-rays and have the database of
information to back them up.
Preliminary x-rays (under 24 months) are read
by one Certified Radiologist, while the x-rays for permanent certification
(24 months or older) are read by three Certified Radiologists. It takes a
specialist to give you the correct readings vs. a local vet who is used to
many breeds, but is not specialized in reading Hip/Elbow x-rays, much less
Fila hip/elbow x-rays.
Another thing to consider is that this is a buyer's problem, as the puppy
buyer will get stuck with the cost of hip/elbow x-rays, medications,
diagnosi and or hip/elbow surgery if the pup turns out to be dysplastic.
Since dysplasia can come from many genes, we probably will never be able to
eradicate it, but i have found by breeding only prelimed or OFA certified
stock, it lessens the number of dysplastic offspring.
I feel that having good structure is just as
important as having good temperament or a "proper" head.
So, breeders, please OFA or PennHip and help
us build the database so we know how extensive the problem is in our breed.
Buyers, push the breeders you are talking to
about prelim or permanent certification of their breeding stock, and ask to
see the certification of the parents!
Who knows, it could save your Fila a lot of
pain and you a lot of money.
