About the Dog Aging Project

The Dog Aging Project is an innovative initiative that brings together a community of dogs, owners, veterinarians, researchers, and volunteers to carry out the most ambitious canine health study in the world. Our work is centered on two fundamental goals: understanding how biology, lifestyle, and environment influence aging and intervening to increase healthspan, the period of life spent free from disease.
Our team of 40+ researchers, led by Dr. Daniel Promislow and Dr. Matt Kaeberlein at the University of Washington and Dr. Kate Creevy at Texas A&M, has built a collaborative, open data research platform that harnesses the power of community science, allowing dog owners to participate in scientific research efforts. The Dog Aging Project is supported by U19 grant AG057377 from the National Institute on Aging, a part of the National Institutes of Health, and by private donations.

About the Health and Life Experience Survey

The Health and Life Experience Survey is the foundation for all research conducted by the Dog Aging Project. Available through an individualized research portal, the Health and Life Experience Survey consists of ten sections and asks 200+ questions about lifestyle, environment, behavior and health. Upon completion of the Health and Life Experience Survey, enrolled dogs become members of the research cohort called the Dog Aging Project Pack.

About the Owner Contact Instrument

The Dog Aging Project is a longitudinal research study. Dogs of any age can be enrolled in the project. Once they join, our team strives to maintain a lifelong, collaborative relationship with the owner as well as the dog's primary care veterinarian. The Owner Contact Instrument is one of multiple instruments that we use to stay in contact with our participants.

About the Dog Demographics Instrument

The Dog Aging Project is open to all dogs, young and old, purebred and mixed breed, intact and altered. The breadth of diversity represented by the members of the Dog Aging Project Pack is part of the power of the dataset, which includes owner-reported information from the Dog Demographics Instrument. For many cohort members, this information is validated through veterinary electronic medical records and genetic assays.

About the Dog Behavior Instrument

The Dog Behavior Instrument collects data on canine behavioral traits such as excitability, agression, fear, affection, and trainability. These variables provide baseline information. Other validated survey instruments supplement and extend the Dog Behavior Instrument.
Survey Questions: Dog Behavior

Section 1: Excitability

Some dogs show little reaction to exciting events, while others become highly excited at the slightest novelty. By checking a number on the following 5-point scale (0=Calm, 4=Extremely excitable), please indicate your own dog's recent tendency to become excitable in the following circumstances.

Section 2: Aggression

Most dogs display aggressive behavior from time to time (e.g., barking, growling, baring teeth, snapping, etc.). By checking a number on the following 5-point scale (0=No aggression, 4=Serious aggression), please indicate your own dog's aggressive behavior in the following circumstances.

Section 3: Fear and Anxiety

Dogs often show signs of anxiety or fear when exposed to particular sounds, objects, persons or situations (e.g., crouching or cringing with tail tucked between the legs; whimpering or whining, freezing; trembling; or attempting to escape or hide). Using the following 5-point scale (0=No fear, 4=Extreme fear), please indicate your own dog's recent tendency to display fearful behavior in the following circumstances.

Section 4: Separation-related Behavior

Some dogs show signs of anxiety when left alone, even for short periods of time. Thinking back over the recent past, how often has your dog shown each of the following signs of anxiety when left, or about to be left, on its own?

Section 5: Attachment and Attention-seeking

About the Owner Demographics Instrument

The Dog Aging Project is a comprehensive investigation of dog health. That means we want to study all dogs from all kinds of homes. Demographic information about participating dog owners is de-identified and analyzed to identify gaps in participation. Our current participant community is predominately white, with average household incomes and education levels that are higher than the average measured across all people living in the US. We recognize that this does not accurately or adequately represent all American dog owners. We want to change that. Equity is a core value of the Dog Aging Project. We believe that our science is stronger when we include people from diverse backgrounds.
