Health Matters:
 The Sealyham Terrier is a hardy breed with very few serious health problems.  None are life-threatening.  Sealyhams are generally long-lived; most Sealyhams live healthy lives past the age of 14, some up to 17 years old.  Some health concerns affecting Sealyhams include allergies, ear infections (often related to allergies), bladder infections and bladder stones.  Some issues that appear sporadically in the breed include back problems, demodectic mange and epilepsy.  When looking for a Sealyham Terrier puppy, ask breeders if they have seen any of these  health problems in their lines.  Deafness is not seen much at all, despite the white coat color.

One problem that was cropping up in the past was primary lens luxation, or PLL.  It is called primary because if left untreated, it can cause glaucoma, which would be a secondary disease.   In primary lens luxation, the lenses of the eyes become dislodged, requiring corrective surgery.  The ASTC contributed financial support as well as blood samples and pedigree information to Dr. Gary Johnson’s Canine Health Foundation research project which played a pivotal role in identifying the genetic marker for PLL.  By finding the genetic marker, a  DNA test was developed.   PLL is a simple recessive gene.

In many cases, the lens would luxate after the dog was the age of two, usually after he had been bred at least once.  Sealyham Terrier breeders can now utilize this new DNA test on their dogs before  they are used in their  breeding programs.  If you’re looking for a Sealyham Terrier puppy, ask breeders if they are using the PLL DNA test.

Please see our Sealy Health Guard site for more information.
In 2010 the ASTC opened a new health registry called the SealyHealthGuard. In it, owners and breeders can register their dogs for free and track any health information they feel is relevant for each dog. This information is verified by sending veterinary information to the webmaster. The ASTC is now also a member of CHIC, the canine health database sponsored by the AKC Canine Health Foundation and OFA. For a Sealyham to be a part of CHIC, DNA results for primary lens luxation and a yearly CERF test must be submitted.
