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 =
- p = W/Wm
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.
