Calculated Energy Requirements

Puppy Energy Requirements

The equation used for puppy energy requirements in table 1 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 =

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.
