How it works
Divide the weight of the bag by the amount fed each day, then round down to whole days. Feeding amounts on food labels are a starting point. Your vet can suggest a better amount for your pet.
Worked example
A bag of 15 lb that is fed at 0.5 lb a day lasts about 30 days.
Questions
Why round down?
Rounding down leaves a margin, so you can reorder before the bag runs out.
Does the bag weight include the packaging?
No. Use the food weight printed on the bag, not the weight with the bag.
What about treats?
Treats are food too. Subtract the treat amount from the daily total for a more accurate count.
