Frequently asked questions
How is daily dog food calculated?
We use the standard resting energy requirement formula (70 × body-weight-in-kg^0.75) multiplied by a life-stage factor, then divide by your food's calories per cup.
Should I ask my vet?
Yes — especially for puppies, seniors, or dogs with health conditions. Use our numbers as a starting point for that conversation.
