What monthly budget feeds a medium-sized dog on premium food?

A medium-sized dog of around 15 kg (33 lb) sits between the small and large profiles, with a maintenance need on the order of 600 to 750 kcal a day. Its food budget is intermediate and stays driven by the food's density and the price per gram, converted into a cost per day rather than a price per kilo. In depth ### An intermediate profile, an identical method A medium dog does not change the calculation rule, only the values: a maintenance need of about 600 to 750 kcal a day for 15 kg, a ration derived from the food's density, and a cost obtained by multiplying the ration by the price per gram. The budget lodges between the public small-dog and large-dog benchmarks, scaling with body weight (Woopets, consulted 2026). On this profile, the two saving levers coexist without either dominating. A large format stays consumable within a reasonable window and lowers the price per gram, while a high density reduces the ration. A useful point: at equal need, moving from a 350 kcal per 100 g kibble to a 400 kcal per 100 g kibble lowers the ration by about one eighth, which stretches the bag by as much. ### Verify before concluding to a saving A higher density only lightens the budget if it is verified, ideally tested by the maker and not merely calculated. The modified Atwater calculation can underestimate the real kcal and distort the ration (Petfoodindustry, on the WSAVA guidelines). Asking for the measured metabolisable energy secures the cost-per-day calculation.
