Every six months, Casey undergoes careful cardiac testing at a lab; she has been through extensive genetic profiling and is now enrolled in a drug trial that researchers believe could extend her life. Casey, an 11-year-old labrador-German shepherd cross who lives with her owner Kate Saunders in Massachusetts, is part of the growing effort to help dogs live better for longer, and which gerontologists hope may improve human longevity too.
Late last year, the US Food and Drug Administration (FDA) centre for veterinary medicine gave conditional approval for a drug created by San Francisco-based biotech company Loyal that could be available as a life-extending tool for large dogs by 2026.
