Veterinary medicine is less regulated than human medicine, and so trial and error experiments may allow faster innovation that would benefit both dogs and humans.
(p. D3) In late 2019, scientists began searching for 10,000 Americans willing to enroll their pets in an ambitious new study of health and longevity in dogs. The researchers planned to track the dogs over the course of their lives, collecting detailed information about their bodies, lifestyles and home environments. Over time, the scientists hoped to identify the biological and environmental factors that kept some dogs healthy in their golden years — and uncover insights about aging that could help both dogs and humans lead longer, healthier lives.
Today, the Dog Aging Project has enrolled 47,000 canines and counting, and the data are starting to stream in. The scientists say that they are just getting started.
“We think of the Dog Aging Project as a forever project, so recruitment is ongoing,” said Daniel Promislow, a biogerontologist at the University of Washington and a co-director of the project. “There will always be new questions to ask. We want to always have dogs of all ages participating.”
But Dr. Promislow and his colleagues are now facing the prospect that the Dog Aging Project might have its own life cut short. About 90 percent of the study’s funding comes from the National Institute on Aging, a part of the National Institutes of Health, which has provided more than $28 million since 2018. But that money will run out in June, and the institute does not seem likely to approve the researchers’ recent application for a five-year grant renewal, the scientists say.
“We have been told informally that the grant is not going to be funded,” said Matt Kaeberlein, the other director of the Dog Aging Project and a former biogerontology researcher at the University of Washington. (Dr. Kaeberlein is now the chief executive of Optispan, a health technology company.)
. . .
Steven Austad, a biogerontologist at the University of Alabama at Birmingham who is not part of the research team, said he was surprised that the researchers’ grant might not be renewed. “The importance of the things they publish and the depth of detail will increase over time, but I thought they got off to a really good start,” he said. “A large study like this really deserves a chance to mature.”
Dr. Austad’s miniature dachshund, Emmylou, is enrolled in the Dog Aging Project. But at 2 years old, he noted, Emmylou is “not going to teach them a lot about aging for a long time yet.”
The project’s innovative approach might have worked against it, Dr. Austad added. Reviewers accustomed to evaluating short-term research on lab mice and long-term studies of humans may not have known what to make of an enormous epidemiological study of pet dogs.
Whatever the reason, the refusal to commit to more funding is “wrong,” Dr. Kaeberlein said. “It’s just really, really difficult to justify this decision, if you look at the productivity and the impact of the project.”
That impact extends beyond the findings themselves, he added. “This project has engaged almost 50,000 Americans in biomedical scientific research.”
Over the last few years, Shelley Carpenter, of Gulfport, Miss., has provided the researchers with regular updates on and medical records for her Pembroke Welsh corgi, Murfee. (She also collected a cheek swab for genomic sequencing.) Ms. Carpenter, whose previous corgi died from a neurodegenerative disease similar to A.L.S., hoped that the project might produce new medical knowledge that could help both dogs and people.
