Currently, we have three additional studies that include subsets of dogs already in the Dog Aging Project Pack. These include a genetic study called Foundation; a physiology study called Precision; and a controlled, clinical trial of a drug called rapamycin called TRIAD. To select dogs for these cohorts, our research team will be trying to balance age, gender, size, breed, and geography. If your dog is invited to join any of these additional studies, we will give you more detailed information, and you will be able to decide whether or not you want to participate.
