Polynomial smooth plot of average percent fat (95% CI) by age for each longevity category. Groups are based on tertiles of survival: expected (red line), long-lived (white line) and exceptional (orange line) for 39 dogs including all available DEXA data. Mean percent fat increased until approximately 10 years of age for dogs in the expected and 11 years for the long-lived groups and up to 12 years of age for exceptional group. After these ages, the percent fat stabilised
