Dedicated to making a genuine impact on the future health of the breed.
In 1997, a small community of Portuguese Water Dog enthusiasts joined together and dedicated their time, money, hard work, and hearts to building a healthier future for Portuguese Water Dogs (PWDs). From their collaborative efforts, the Portuguese Water Dog Foundation was formed for the sole purpose of supporting research to improve the health of the breed in not only breed specific diseases but also diseases like the various cancers and viral diseases that affect the general canine population including PWDs.
The Portuguese Water Dog Foundation is a permanent and separate entity that was established for the sole purpose of supporting health research for the benefit of the Portuguese Water Dog. The Foundation followed the lead of many other breed specific groups, which have established Foundations that are separate entities successfully supporting research for the health of their specific breed. While the Foundation is not affiliated with the Portuguese Water Dog Club of America, we do share a common goal – the health of the breed.
The Portuguese Water Dog Foundation is a 501(c)(3) charitable organization. All Officers and Board members of the Foundation serve as unpaid volunteers.
RESEARCH
Research the Foundation has sponsored or co-sponsored has contributed to the future health of the breed in significant ways:
The gene that caused Juvenile Cardiomyopathy (JDCM) and Puppy Eye Syndrome (MOS), which resulted in puppies dying, was found, and a genetic test was developed.
The gene that caused prcd PRA (prcd Progressive Retinal Atrophy) and non-prcd PRA (EOPRA), which caused dogs to go blind, was found and a genetic test was developed.
In addition to the above successes, the Foundation continues to sponsor research related to cancer (hemangiosarcoma and lymphoma), IBD and Addison’s.
PARTNERSHIP
The Foundation partners with the AKC Canine Health Foundation and the Morris Animal Foundation on multi-breed health related research that also affects Portuguese Water Dogs.
In addition, the Foundation partners and communicates with the Portuguese Water Dog Club of America to co-sponsor breed specific health research.
Over the years the Foundation has partnered with major universities in breed specific research as well as the Rabies Challenge Fund.
The Foundation is proud to partner with a major university to build a reference genome of the Portuguese Water Dog that will be publicly available to researchers.

Our History
The 2025 PWD Foundation Health Survey provides the most comprehensive look at the health of Portuguese Water Dogs in more than 20 years. More than 3,300 dogs were represented, providing valuable information about health conditions, longevity, causes of death, and other aspects of health in the breed.
Rapid Response funding to determine risk of Portuguese Water Dogs with frequent exposure to freshwater developing canine schistosomiasis as a result of exposure to heterobilharzia americana (HA). The concern that the dogs of the PWD breed have at least as much risk as the general population of dogs based on…Read More
This project will generate a high-quality, reference genome combining the latest technologies, to produce a PWD genome assembly of unprecedented accuracy and completeness. Additionally, this assembly will enable researchers to compare PWD genomes with those of other breeds – unlocking insights into inherited variation that governs morphology, disease risk, and…Read More
Launched a comprehensive health survey inviting all Portuguese Water Dog owners—across the U.S. and around the world to complete a survey for any PWD they own/have owned born since 2005. Results will be critical to helping us better understand the current health status of PWDs and to identify any emerging…Read More
