==Puppy Energy Requirements==
The equation used for puppy energy requirements in table 1 is based on current body weight and expected adult weight.
The equation used for puppy energy requirements in table 1 is based on current body weight and expected adult weight.
:::130 x BW (KG)<sup>0.75</sup> x 3.2 x [e<sup>(-0.87p)</sup> - 0.1]
:::130 x W<sup>0.75</sup> x 3.2 x [e<sup>(-0.87p)</sup> - 0.1]
Where:
Where:
:::p = W/Wm
:::p = W/Wm
:::W = actual body weight in kg
:::Wm = predicted mature adult weight in kg
:::e = base of natural log ~2.718
:::e = base of natural log ~2.718
N.B. The table displays the columns in age in months, not current weight of the puppy. This is because the energy requirement data at a given age are calculated from the expected weight at that age – and this varies depending on the anticipated adult weight of the dog.
