How to use this tool

Calculate resting energy requirement as a reference for a veterinary feeding discussion.

Enter the values in the units shown, then select Get result. Check the assumptions below before using the output. You can print the result or copy it into your own notes.

Method and assumptions

RER = 70 × body weight in kg ^ 0.75, in kcal/day. Reference: AAHA nutrition and weight management guidelines.

Use the result thoughtfully

RER is not a daily feeding prescription. Growth, pregnancy, disease, weight loss and individual needs require veterinary guidance. Do not restrict food from this result alone.
