from Sealy Health Guard
This site was originally set up for the use of all Sealy owners to track the prevalence
of Primary Lens Luxation (PLL) in our breed, utilizing all the information in our SIGHT Registry
collected by GDC (Institute for Genetic Disease Control). Thanks to the participation of
nearly 200 Sealyham owners and breeders we were able to send blood samples from dozens of affected
dogs and their relatives to Dr. Gary Johnson's research project at the University of Missouri. Those
samples were crucial to his success in identifying the defective gene that causes PLL in Sealys and
several other terrier breeds. More than 100 Sealy owners have had their dogs tested and these
results have been added here in the Sealyham Terrier Health Guard Database.
With the new DNA test for PLL, all Sealyham Terrier owners can now test their Sealys for
the good of our breed. We can eliminate scourge of Lens Luxation within a few generations.

BUT THIS SITE IS NOT JUST FOR EYE PROBLEMS. It's
designed to track and provide
information for any and all diseases and anomalies
that plague our breed - skin problems, epilepsy,
back problems, cancer, deafness and others. We
need complete health information on our dogs
so we can see where the major problems are
and invest our research dollars accordingly.
In the "Comments" section of your dog's information
sheet you can share with all
of us how you dealt with any health issues
your own Sealy has had.
Through this global database we can
share health, pedigree and breeding status
information from all over the world.

NEW ADDITION! Breeding Guidelines to use with the PLL DNA Test
We've created this online resource as the "go-to" place for health care information. From
a review of flea-control products to a report on vaccination studies, you'll find articles and resources
dedicated to helping you keep your Sealyham Terrier healthy in
Many of the articles recently added are
by Leslie Manis, ASTC Health/Genetics Chairman, and were originally published in the Barks.
We will be adding new resources regularly from a wide range of sources. Do you have
a special request for info? Contact Sandy Schneider, editor of the Health Pages.
DNA Test for Lens Luxation

Thanks to the participation of nearly 200 Sealyham owners and breeders in the Sealyham SIGHT Registry from
2004-2009, we were able to send blood samples from dozens of affected dogs and their relatives to Dr.
Gary Johnson's research project at the University of Missouri. Those samples were crucial to his success
in identifying the defective gene that causes lens luxation in Sealys and several other terrier breeds.
Now, with an inexpensive DNA test available through OFA, you can find out if your dog is at risk for becoming
affected or for carrying the defective gene. CLICK for more
GENE INHERITANCE CHART
Lens Luxation is an "autosomal recessive" genetic disease. To be affected,
the dog must inherit a copy of the defective gene from each parent. A
dog with only one copy won't become affected, but it
will be a "carrier".
For a look at how recessive inheritance works,
