Eyes
Progressive Retinal Atrophy (PRA) is an eye disease that will eventually cause blindness. Progressive rod-cone degeneration (PRCD) is the form that affects the Portuguese Water Dog. It cannot be diagnosed by an eye exam until the dog is an adult, however, there is a DNA marker gene test than can determine if dogs are normal, carriers or affected. The test is available from Optigen. Go to www.optigen.com for additional information.
To ensure the overall health of the eyes, an annual eye exam by a Board Certified ophthalmologist is recommended for dogs to be used for breeding. The Canine Eye Registry Foundation (CERF), issues a certificate to owners for dogs with normal eyes. The evaluation is only valid for one year. Both parents should have a current CERF exam and Optigen rating, and a copy should be shown to the prospective buyer. Visit 404 Veterinary Hospital at www.veter.ca for more information.
Storage Disease GM-1
GM-1 Storage Disease is a rare disease which affects humans and Portuguese Water Dogs. It is a genetically transmitted fatal metabolic disorder which occurs when two carrier dogs are bred together. Affected puppies will not reach adulthood. Non-Carrier or Carrier and Indeterminate PWDs have a normal life expectancy.
A DNA blood test is available through HealthGene. Results of the blood test will determine "Normal" or "Carrier" status of the tested dog. Certificates are issued by the Laboratory for all tested dogs. For more information visit www.healthgene.com .
