About PupRange

PupRange is a small set of free puppy and dog calculators. Each one turns published veterinary growth, nutrition and toxicity data into a range, so you can see how sure an estimate is.

Who runs it

PupRange is built and run by one person in Izmir, Türkiye, who is not a veterinarian and has no veterinary training. The site is not a clinic, a pet store or an insurance agency.

How the calculators are built

  • Every formula starts from a published source: veterinary guidelines, textbooks or peer-reviewed studies. Steps that are our own, such as the 70% lower edge for “up to” breeds, are labeled on the methodology page. Each tool lists its sources with the date we last checked them.
  • Results come from fixed formulas and data tables that run in your browser. No calculator uses AI to produce a result.
  • AI assistants help draft page text and code. Formulas, numbers and sources are checked against the original publications, with automated tests for every formula, and anything not yet checked is marked on the methodology page.
  • No page carries a veterinarian review label yet. A label appears only with the reviewer's name and the review date, here and on the tool.

Read the editorial policy for how we choose sources and fix mistakes, and the veterinary disclaimer for what an estimate can and can't tell you.

How the site makes money

The calculators are free. The site may show ads and some labeled partner links, which pay us a commission if you buy or request a quote. Neither ever changes a result. There are no paid placements. See advertising and the affiliate disclosure.
