The Dog Aging Project is a long-term biological study of

that influence human life span. Since dogs age significantly more rapidly than humans, data on aging can be generated much more rapidly using a dog model than in human studies. A further premise is that the longitudinal portion of the project seeks to understand the underlying biology of aging, as opposed to understanding individual age-related diseases. In this respect, if the aging process itself is addressed, then several age-related diseases could be delayed or avoided simultaneously. This is important because elderly individuals often have multiple
