Senior Dog Feeding Calculator
Senior dogs often need fewer calories as activity drops, even when the scale stays flat. Less-active seniors use a 1.4 factor in this model — lower than a typical neutered adult at 1.6.
This worked example is a 70-pound senior on two meals. Controls below adjust weight, calories per cup, and paper size. The assumptions block prints every factor and density figure used.
Arthritis, dental disease, and kidney issues change what food is appropriate — this tool estimates quantity only. Your vet's prescription diet instructions override any calculator.
