 The dog aging project is ready for takeoff. DAP is an initiative to study aging and pet dogs, which may hopefully lead to treatments to slow down or reverse aging. DAP scientists think dogs are good models for human aging, given how dogs get similar age-related diseases and share our same living environment. DAP is currently preparing to enroll large cohorts of dogs to study the effect of rapamycin on dog lifespan as well as several other health-related endpoints.
