So, as Casey eagerly participates in her drug trial, she represents not only the hope for a longer life for dogs but also a beacon of possibility for human health. With each breakthrough, we inch closer to a world where both dogs and humans can lead healthier, happier, and more fulfilling lives.

In the quest to extend the healthspan of our furry companions, researchers and biotech companies are exploring innovative approaches to combat aging in dogs. By targeting specific biological processes and harnessing the power of cutting-edge drugs, they hope to not only improve the lives of our beloved pets but also gain valuable insights into human longevity.

One key area of focus is the role of insulin-like growth factor (IGF-1) in canine aging. Studies have shown that larger dogs tend to have shorter lifespans than smaller ones, and this correlation may be linked to higher levels of IGF-1 in their bodies. San Francisco-based biotech company Loyal has developed a drug called LOY-001 that targets IGF-1, with the goal of reducing its levels and potentially extending the healthspan of larger dogs. While initial results have been promising in terms of reducing IGF-1 levels in the blood, further research is needed to establish a definitive causal relationship between high IGF-1 and accelerated aging.

Another exciting project in the field of canine longevity is the Dog Ageing Project (Dap), a collaboration between the University of Washington and Texas A&M University. Dap is conducting a trial to investigate the effects of the drug rapamycin on canine healthspan. Rapamycin inhibits a protein called mTOR, which plays a crucial role in regulating cell growth and metabolism. Previous studies have shown that low doses of rapamycin can extend the lives of laboratory animals by up to 14% in older age. Preliminary results from the Dap trial have shown improvements in the health and behavior of dogs taking rapamycin, raising hopes for a formulation of the drug that could be available within the next two years. This development could potentially benefit not only dogs but also cats and other animals.

Dogs offer a unique opportunity for studying the aging process due to their close proximity to humans in terms of environment, lifestyle, and diseases. Their microbiota, the community of bacteria present in their digestive tract, is more similar to their owners than to other dogs. Additionally, dogs have electronic medical records in many countries, making it easier to track their health history. By studying the aging process in dogs, researchers hope to gain valuable insights into human longevity and bridge the gap between animal and human research.

Several areas of research show promise for both human and canine healthspan extension. One such area is the exploration of urolithin A, a natural product that activates a process called autophagy. Autophagy is the body’s way of cleaning out damaged cells and recycling their components, and its decline is associated with aging. Urolithin A has been shown to enhance autophagy and improve cellular health in animal studies, offering potential benefits for both humans and dogs.

Another area of interest is parabiosis, a procedure where older mice receive blood from younger mice. This process has shown remarkable results in rejuvenating older mice, with improvements in muscle function, brain health, and overall vitality. While parabiosis has yet to be tested in dogs, it holds promise as a potential avenue for healthspan extension in both species.

Targeting metabolic pathways is another promising approach to extending healthspan. Enzymes like AMP-activated protein kinase (AMPK) and drugs like metformin, commonly used to treat diabetes, have been shown to have potential benefits for longevity. AMPK helps regulate cellular energy levels and has been implicated in the aging process. Metformin, on the other hand, has been shown to have anti-aging effects in animal studies by improving insulin sensitivity and reducing inflammation. These metabolic interventions hold promise for both human and canine healthspan extension.

In conclusion, the field of canine longevity research is rapidly expanding, with innovative approaches being explored to extend the healthspan of our furry companions. By targeting specific biological processes and harnessing the power of cutting-edge drugs, researchers hope to not only improve the lives of dogs but also gain valuable insights into human longevity. From targeting IGF-1 to exploring the effects of rapamycin, dogs are serving as a bridge between animal and human research. With potential crossover areas such as autophagy activation, parabiosis, and metabolic pathway targeting, the future looks promising for both human and canine healthspan extension.


Advancements in veterinary medicine have the potential to revolutionize human longevity. Recent breakthroughs in drugs like LOY-001 and rapamycin have shown promising results in extending the healthspan of dogs, opening the door to similar advancements in human health. Dogs, as our loyal companions, share many of the same health concerns as humans, making them an ideal model for studying the aging process.

While challenges still exist in developing effective longevity drugs, the pursuit of extending our lifespan continues unabated. The desire to live healthier and happier lives drives scientists and researchers to explore new frontiers in medicine. And as we strive to improve the healthspan of those we love, whether they walk on two feet or four, the potential benefits for both humans and animals are vast.
