As answered by people managing PawRation and ShellNewHandler.
PawRation's answer
Every number is source-verified. Our calorie database of 80 real dog foods is transcribed from manufacturer labels with public check dates — no other feeding calculator offers verified brand-level data alongside the WSAVA veterinary formula, breed-specific charts for 61 breeds, and a transparent methodology page.
PawRation's answer
Three reasons: (1) verified data — portions are calculated from your actual food's label values, not generic estimates; (2) breed-aware — 61 breed guides with growth charts and feeding notes; (3) transparent — a public methodology page with sources, check dates, and a corrections log. Most calculators ask for numbers and give you an answer; we show you where every number came from.
PawRation's answer
US dog owners who want to feed precisely rather than guess — especially owners of growing puppies who need to recalculate portions every few weeks, and anyone switching foods who needs to convert between kcal/cup values.
PawRation's answer
It started with a simple observation: the feeding chart on every dog food bag assumes one generic dog, and it's often wrong by 30% or more. We built PawRation to answer the question every owner asks — "how much should I feed my dog?" — with the same veterinary formula a vet would use, but personalized to the individual dog and the exact food in the cupboard.
