Affiliate disclosure

PawCalculators is free to use. To help keep the lights on, some calculator pages include partner links to retailers like Chewy and Amazon.

If you click a partner link and buy something, we may earn a small commission. It does not change the price you pay.

As an Amazon Associate we earn from qualifying purchases. Chewy and other retailer links may also be affiliate links when those programs are enabled.

We only attach shopping links where they relate to the calculator result (food after calorie math, crates after size math, and so on). We do not push products on emergency or medication tools.

Calculator results are estimates for education, not veterinary advice. Always check labels, size charts, and your vet when it matters.
