Figure 2. Calculated cellular damage increases as a function of age in two dog breeds. (physiological parameters in Eq. 1 required to produce this figure: B₀ = 3158 Joules/(day.gram^0.69) [7,8], E_m = 5000 Joules/gram, and ε = 0.999) [34,40,53]. The solid and dashed arrows indicate the ages at which ~ 90% of the adult masses are reached in two dog breeds. These ages were estimated from the growth equation, and the birth and adult masses of both dog breeds.
