Puppy Energy Requirements

The equation used for puppy energy requirements is based on current body weight and expected adult weight.

130 x BW (KG)0.75 x 3.2 x [e(-0.87p) - 0.1]

Where:

p = W/Wm
W = actual body weight
Wm = predicted mature adult weight,
e = base of natural log ~2.718
BW =

However, the columns are 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.
