There are health issues surrounding every breed of dog. Some breeds have more than others. The havanese breed has a few health concerns that you should read up on before making the educated decision to add one to your family.
We've all seen what happens to other breeds when their breed clubs
are reactive instead of proactive with health issues or when the
popularity of the breed explodes and breeders are out to meet the
demand for puppies without any regard to the breed's health. This is
when the breed's general state of health declines.
With that
in mind the Havanese Club of America has set criteria as to what health
tests must be done to all dogs used in a breeding program to
recieve a CHIC number (see paragraph below). The basic health tests are
annual eye examinations (CERFs), BAER testing (hearing), patellas (knees) and hips certified by the Orthopedic Foundation for Animals, better known as OFA.
These test results, if registered with OFA can be verified online at www.offa.org.
All you need is the dog's registered name and the test results will be
available. Look at each test's result....hips for example, have
ratings. If the dog in question has had all four tests registered
with OFA the dog would also receive a CHIC number (canine health information center) which can be verified at www.caninehealthinfo.org. Again, look at each test's result.
If, for some reason, the breeder has not registered the tests
results with OFA obtain copies of the test results before going ahead
and adopting the puppy. Do not accept that 'those health problems
don't exist in my lines' as an acceptable answer. No one can honestly
make that claim.
Currently we just don't know exactly how some
of these issues are inherited Until we know for sure, we feel
that health testing breeding dogs is just one way to help in keeping
these problems from becoming a serious health issue.
The Havanese Club of America has
a page on havanese health. The data and pass/fail percentages seen on
their health page only correlate to those havanese owner's who have
submitted results to OFA. Most breeders submit only those tests with
passing results so therefore, the percentages that are posted on the
HCA website are skewed*.
A perfect example of skewed results is the Legg Calves
Perthes health test. It is a young puppy disease (generally 6
months to one year
old). OFA hip xrays are used for this test but..... the xrays are
taken on dogs 2 years old or older. Therefore, those
dogs with Legg Calves Perthes are not having their hips rayed for OFA
purposes. I know of numerous havanese puppies that have
had this disease, including one of our own. Did we have her
x-rayed at 2
years old so we could submit the results to OFA? No, we know from
her earlier x-rays that her hips are not 'normal'.
*(The only test where veterinarians submit data independant of havanese owners is CERF, so those results are reliable.)
