Can We Make Our Pets Live Longer? The Science of Pet Longevity

ReProgram Episode 22: 🐾 *EPISODE OVERVIEW* This episode asks a deceptively simple question: Can we actually help our dogs and cats live longer, healthier lives? We explore why companion animals are unusually powerful models of aging, why “one dog year equals seven human years” is biologically wrong, what the Dog Aging Project is revealing, what pet owners can reasonably do today, and where emerging interventions like rapamycin, canine longevity drugs, AIM therapy, and gene therapy fit into the evidence. 🔑 *KEYWORDS* Pet longevity, dog aging, cat aging, healthspan, Dog Aging Project, rapamycin, TRIAD Trial, Loyal, feline kidney disease, AIM/CD5L, gene therapy, pet nutrition, body condition, muscle preservation, geroscience, comparative aging, healthy aging, veterinary medicine 💡 *KEY TAKEAWAYS* • Dogs and cats may be powerful real-world models of aging because they share our homes, environments, behaviors, and many naturally occurring diseases. • Dog years are not human years. Aging rates change throughout life and vary dramatically by breed and body size. • For most pets, the strongest longevity strategies today remain surprisingly conventional: appropriate body composition, good nutrition, movement, muscle preservation, dental care, pain management, preventive medicine, and early disease detection. • Rapamycin, dedicated canine longevity drugs, AIM therapy, and gene therapies are scientifically exciting—but they remain at different stages of experimental validation. • Healthspan matters more than lifespan at any cost. More time only matters if we preserve the experiences that make an animal recognizably itself. 🎙️ *THE REPROGRAM PERSPECTIVE* Pet longevity is a perfect example of why we need to separate mechanistic plausibility from meaningful outcomes. A supplement that changes a biomarker is not necessarily extending healthspan. An intervention that treats one age-related disease is not necessarily slowing aging throughout the entire organism. And an exciting mouse study is not a reason to start experimenting on your pet. *Mechanism over marketing. Evidence over anecdotes. Healthspan over lifespan at any cost.* *OFFICE ARTIFACT* On the desk: Tut, 3 year old Hairless Peterbald Sphinx: https://www.instagram.com/tutandbeebe.sphynx/ ⏱️ *CHAPTERS* 0:00 Can Our Pets Live Longer? 2:10 Welcome: The Science of Pet Longevity 3:52 Why Pets Are Living Aging Studies 7:58 The Myth of “Dog Years” 10:57 Inside the Dog Aging Project 14:19 What Pet Owners Can Do Right Now 16:56 Is There a Longevity Diet for Pets? 20:08 Oral Health and Preventative Care in Pets 21:40 Rapamycin and the TRIAD Trial 23:27 The First Canine Longevity Drugs? 24:30 AIM Therapy and Feline Kidney Disease 27:48 Gene Therapy for Aging-Related Disease 29:06 Purina and the Pet Longevity Industry 31:02 The ReProgram Pet Longevity Scorecard 33:54 Tut, Healthspan & Why More Time Matters 🔬 *SCIENCE & PROGRAMS MENTIONED* Dog Aging Project A large longitudinal effort studying how genetics, environment, lifestyle, and molecular factors shape aging and health in companion dogs.
