How It Works
Life expectancy is calculated from the breed average adjusted for lifestyle factors. Kealy et al (JAVMA 2002) demonstrated lean-fed dogs lived 1.8 years longer. Urfer et al (Prev Vet Med 2020) identified exercise, veterinary access, and weight as the key modifiable longevity factors. Sources: Michell AR. Longevity of British breeds of dog. Vet Rec 1999; Kealy RD et al. JAVMA 2002; Urfer SR et al. Prev Vet Med 2020.
