Within the Dog Aging Project, there are multiple lines of scientific inquiry. Each has specific protocols for data collection, participant selection, and data analysis. These protocols were vetted by the National Institute on Aging during the granting process. Everything that we do is guided by the animal care and welfare requirements of our academic institutions, which we satisfy at the highest level. If your dog is invited into additional studies beyond the Health and Life Experience Survey, you will be provided with details about the specific activities you would be asked to do with your dog in order for you to make an informed decision about whether or not to participate.
