==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 W<sup>0.75</sup> x 3.2 x [e<sup>(-0.87p)</sup> - 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.
