Many genetic resources are available for the breeder of Portuguese Water Dogs. Our breed is fortunate to have several gene tests at our disposal for diseases that would otherwise be devastating to our breed. By utilizing these genotypic and phenotypic testing options, breeders can make breeding choices that limit the occurrence of certain diseases in our dogs. Here are some resources offering testing for the most common diseases found in the Portuguese Water Dog as well as information of other more obscure health issues.
PennGen is a genetic testing facility operated through the Section of Medical Genetics at the University of Pennsylvania’s School of Veterinary Medicine. It is a collection of laboratories that coordinate as a not-for-profit unit, offering routine testing for a variety of genetic diseases, metabolic screening for inborn errors of metabolism, and a number of other diagnostic genetic services. PennGenn also engages in research to uncover the genetic basis of a wide range of disease in domestic animals. PennGenn offers gene test for the JDCM found in the Portuguese Water Dog.
Is a service company established to provide DNA based diagnoses and information about inherited diseases of dogs. Their founding members have collaborated for decades on projects in the fields of veterinary ophthalmology, molecular diagnostics, and genetics. They provide a wide range of genetic testing, offer genetic counseling, and archival of DNA samples for future tests that may come available. Optigen provides testing for prcd-PRA, GM-1 and IC-13 in the Portuguese Water Dog. Consult their website for information on pricing and various available discounts.
Orthopedic Foundation for Animals
Founded and originally incorporated as a private not-for-profit foundation in 1966, the OFFA originally focused on a means of limiting hip dysplasia in dogs. Since that time, the OFFA has expanded to operate an extensive database of genetic disease in all-breeds and they continue to interpret canine hip radiographs. In addition, they offer a number of genetic screenings and maintain a DNA bank for future canine health research in conjunction with the University of Missouri.
Canine Health Information Center
The CHIC database is a tool that collects health information on individual animals from multiple sources. This centralized pool of data is maintained to assist breeders in making more informed breeding choices and for scientists in conducting research. In order for data to be included in CHIC, test results must be based on scientifically valid diagnostic criteria.
Core to the CHIC philosophy is the realization that each breed has different health concerns. Not all diseases have known modes of inheritance, nor do all diseases have screening tests. Some screening tests are based on phenotypic evaluation, others on genetic testing. With all these variables, a key element of CHIC is to customize or tailor the CHIC requirements to the needs of each breed. These unique requirements are established through input from the parent club prior to the breed’s entry into the CHIC program. Breed specific requirements typically consist of the inherited diseases that are of the greatest concern and for which some screening test is available. Each parent club also drives specific screening protocols.
