Editorial Policy

Who makes this site

PupRange is researched, built, and edited by one person, who runs it alone from Türkiye for dog owners in the United States and is not a veterinarian. Our job is to find the best available published data for each question, apply it carefully, and be clear about its limits.

How we choose sources

We prefer, in this order: guidelines from veterinary professional bodies (for example the American Animal Hospital Association and the World Small Animal Veterinary Association), veterinary reference texts such as the Merck Veterinary Manual, peer-reviewed studies, and breed data published by kennel clubs such as the American Kennel Club. We avoid using other calculator sites, forums, or product marketing as the basis for a number.

• Every tool page has a Sources section that names each source, links to it where possible, and shows the date we last checked it.
• When sources disagree, we use the range they span rather than picking the most convenient figure, and we say that they disagree.
• Breed pages are built from our sourced breed data file. We only publish a page for a breed when we have cited weight and growth data for it.
• We do not invent statistics, quotes, or expert opinions. If we cannot verify something, we leave it out.

How the calculators are built

Each tool has a short "How this is calculated" section with the formula or table it uses, the assumptions behind it, and the cases where it does not apply. The calculation code is tested against worked examples from the cited sources before release. Results are given as ranges, with body condition and breed size taken into account, because a single number would suggest more certainty than the data supports.

Use of software and AI tools

We use software, including AI writing and coding assistants, to help draft text, write code, and check our work. Formulas, numbers, and sources are checked against the original publications, and every formula is covered by automated tests; anything not yet checked against the original is marked on the methodology page. The person who runs the site is responsible for everything that appears on it. No calculator uses AI to generate your result; results come from the published formulas and tables described on each tool page.

Veterinary review status

As of the date at the top of this page, no page on this site carries a veterinarian review label. When a veterinarian's review of a tool or article is published, that page will show the reviewer's name, credentials, state of license, and the review date, and we will list reviewed pages here. We will not use "vet reviewed" labels on any page that has not been reviewed.

Keeping pages current

• We recheck each tool's sources at least every 12 months, and sooner when a source publishes an update.
• Emergency contacts, such as poison hotline numbers and fees, are rechecked at least every 6 months.
• The "Updated" date on a page changes only when we make a real change to its content, not for small layout fixes.

Corrections

If you think a number, formula, or statement is wrong, email hello@puprange.com with the page address, what you believe is wrong, and a source if you have one. We aim to reply within 7 days. If we change a result or a safety statement, we add a dated correction note at the bottom of the page explaining what changed.

Independence from advertisers and partners

Ads and partner links pay for the site, but they do not shape what we publish. Advertisers and affiliate partners do not see content before publication, and no formula or result depends on a partner relationship. See our Advertising Policy and Affiliate Disclosure for details.
