About Paw Checkups
Paw Checkups builds free, accurate pet health calculators for dog and cat owners. No account required, no ads in the way, no generic advice — just the numbers your vet doesn't have time to calculate at a 15-minute appointment.
Every calculator is built on veterinary-standard formulas — RER/MER for food portions, AAHA life stage guidelines for age conversion, BARF ratios from peer-reviewed raw feeding research. We link to sources and explain the math, so you can verify the results rather than just trust a black box.
The pet insurance comparison page is affiliate-supported — we earn a small commission when you buy a policy through our links. This doesn't influence our rankings. We'd rather recommend fewer, genuinely good products than pad out a list for clicks.
Important: Paw Checkups is an informational tool, not a substitute for veterinary advice. Use these calculators to prepare better questions for your vet, not to replace them. If your pet is losing weight, refusing food, or showing any signs of illness, call your vet.
