The equation used for puppy energy requirements 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]
+
+
Where:
+
:::p = W/Wm
+
::::W = actual body weight
+
::::Wm = predicted mature adult weight,
+
:::e = base of natural log ~2.718

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.
