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.

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.

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 W0.75 x 3.2 x [e(-0.87p) - 0.1]

Where:

p = W/Wm
W = actual body weight in kg
Wm = predicted mature adult weight in kg
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.


Table 1: Puppy Energy Requirements (kcal/day)
Age in months
Expected adult weight in kg 1 2 3 4 5 6 9 12 15 18 21
1 56 97 123 137 140 141 adult adult adult adult adult
