Only part of the weight is important for nutrient requirements. It's the metabolic weight. In a food package for dogs or cats, the need for a nutrient can be informed per kg of metabolic weight.
Metabolic weight is calculated as weight0.75. Thus, for example small dogs have a proportionally higher metabolic weight than large dogs.
Metabolic weight is only indicative. The amount of energy or nutrient required varies depending, for example, on the activity of a pet. Especially the energy needs of dogs can vary greatly.
The above counter will give you a calculated metabolic weight. Below are some metabolic weights for certain weight values.
