Healthspan in companion animals
The central question is not only how long dogs live. It is how many of those years are spent in full function: mobile, mentally sharp, metabolically healthy, and able to recover when things go wrong. That is the frame I work in.
Most durable gains available to owners today come from unglamorous inputs: nutrition, body composition, daily movement, sleep, dental and preventive care, and catching metabolic drift early. Pharmacologic approaches, including rapamycin trials, metabolic compounds, and longevity supplements, are worth following honestly. They are one input, not the answer.
This is an active area of my writing, lecturing, and clinical work, and one I'm happy to discuss with press, students, and colleagues.
