Since its inception in 2018, the Dog Aging Project has been a beacon of hope for dog lovers everywhere, collecting valuable data from over 50,000 dogs to unlock the secrets of aging and potentially enhance the vitality of our furry companions.

The researchers behind this initiative have thoughtfully differentiated between two important concepts: a dog’s lifespan, which refers to the total years they live, and their healthspan, the joyful years they spend in good health. The primary aim of the project is to elevate the quality of life for dogs, focusing on their well-being rather than merely extending the number of years they have.

This ongoing research holds exciting possibilities not only for dogs but also for humans, suggesting that what we learn could benefit us all.

“Given that dogs share the human environment and have a sophisticated health care system but are much shorter-lived than people, they offer a unique opportunity to identify the genetic, environmental, and lifestyle factors associated with a healthy lifespan,” shared Dr. Daniel Promislow, a principal researcher supported by a grant from the National Institute on Aging.

The project is currently exploring an intriguing compound known as rapamycin, which has shown promise in extending the lifespan of mice, to see if it can also bring benefits to dogs.

Lead researcher Kate Creevy explained, “My team has done two previous smaller, shorter studies to ensure that the dogs would tolerate it, we didn’t see side effects, and that we could design it.”

The TRIAD trial, part of this expansive study, aims to enroll 580 dogs across approximately 20 clinical trial sites nationwide. This initiative is a shining example of collaboration and dedication to improving the lives of dogs everywhere.

Scientists have been investigating the effects of rapamycin, also known as sirolimus, on humans for quite some time. They have discovered that this medication can positively impact the immune, cardiovascular, and integumentary systems in individuals facing age-related challenges.

Matt Kaeberlein, a colleague of Creevy, reflected on the complexity of aging, stating, “Aging is an immensely complicated and complex biological process, and we still have far to go before we can claim to understand aging at either a molecular or biochemical level.”

Yet, he remains optimistic, noting, “Despite this, great strides have been made, and we now have multiple interventions that could significantly delay aging and age-related disease in both dogs and people.”

This enlightening journey is not just about adding years to the lives of dogs but enriching the lives they lead, ensuring that our beloved pets can enjoy every moment to the fullest.
