We do not conduct, nor are we associated with, any research on laboratory or captive dogs. All the dogs enrolled in the project are companion dogs, living with their owners in private homes. The Dog Aging Project is primarily a longitudinal observational study. This means following the same research subjects over time (the longitudinal part of the study) and measuring, but not manipulating, the same variables over time (the observational part of the study). You can read more about this type of research in our blog post entitled The Power of Paying Attention.
