Canine healthspan medicine
Dogs have eleven body systems. Most care watches one at a time.
K9 Longevity measures every system twice a year, builds a biological age for each, and manages the whole dog against one protocol, so the healthy years last as long as the life does.
11
systems measured, none in isolation
2×
full diagnostic cycles every year
1
protocol, revised as the dog changes
The method
Measure, model, manage, maintain.
01
Measure
A twice-yearly panel across all eleven systems: bloods, imaging, gait, cognition, microbiome and cancer screening.
02
Model
Results become a biological age estimate per system, benchmarked against breed, size and lineage curves.
03
Manage
One protocol for nutrition, loading, sleep, dentistry and pharmacology, revised at every measurement cycle.
04
Maintain
Residential stays at the K9 Longevity Hotel keep the protocol running when you travel, recover or relocate.

Why it matters
The goal is not more years on the calendar. It is more mornings like this one.
The K9 Longevity Hotel
Residency, not boarding.
Private garden suites, circadian lighting, a hydrotherapy hall and a clinical floor with round-the-clock veterinary nursing. Every stay runs your dog's protocol exactly as written, with daily notes and measurements added to their record.
Tour the hotelThought-leadership partner
University of Pennsylvania School of Veterinary Medicine
Our protocols are shaped in dialogue with Penn Vet clinicians and researchers, the reference point for canine internal medicine, oncology and sports medicine. Their scholarship keeps the program honest: nothing enters a protocol without evidence behind it.
How the science works
Membership
The good years, extended.
Membership covers the full diagnostic calendar, your dog's longevity physician, protocol revisions, and priority residency at the hotel. Places are limited per clinician so that every dog is genuinely known.
