About AnimalGrow

What AnimalGrow Is

AnimalGrow is a free, independent website of calculators and reference material for people who live with or keep animals — dog and cat owners, first-time pet parents, and livestock keepers working with cattle, horses, pigs, sheep, and goats. The site is supported by advertising, which is how it stays free to use with no account or sign-up required.

What AnimalGrow Is Not

AnimalGrow is not a veterinary clinic, an animal-science laboratory, or an official body of any kind. It is not affiliated with any veterinary association, breed registry, or agricultural extension service. The tools give estimates built on published formulas and reference ranges — they are a starting point for thinking about an animal, not a diagnosis, prescription, or substitute for hands-on veterinary care. For anything involving an animal’s health, medication, or a real emergency, talk to a licensed veterinarian who can actually examine the animal in front of them.

We don’t claim years in business, a founding story, or a staff of credentialed specialists. This is a small, focused site built around a specific set of tools, kept up and improved over time.

What You’ll Actually Find Here

The core of the site is six calculators, each built around one concrete question a pet owner or livestock keeper runs into:

• The Pet Age Calculatorconverts a dog or cat’s age into human-equivalent years using a size-adjusted veterinary curve rather than the old flat “times seven” rule, and shows the animal’s current life stage.
• The Animal Weight Estimatorturns a heart-girth and body-length tape measurement into an estimated live weight for cattle, horses, pigs, sheep, and goats — useful when there’s no livestock scale on hand.
• The Pet Nutrition Calculatorworks out a dog or cat’s daily calorie needs and grams of food from its weight, life stage, and the food’s energy density.
• The Breeding Calculator projects an expected birth date from a breeding date, covering dogs, cats, cattle, horses, pigs, sheep, goats, and rabbits, each with its own gestation length.
• The Livestock Feed Optimizer sizes a daily feed ration as a percentage of body weight and scales it across a whole herd for daily and monthly totals.
• The Pet Medicine Dosagetool turns a vet-prescribed mg/kg rate into a per-dose and per-day amount. It is educational only — always confirm the actual dose and schedule with your veterinarian before giving any medication.

Alongside the calculators, the Animal Kingdom museum is a browsable collection covering livestock and farm animals, companion pets, popular dog and cat breeds, exotic pets, and wildlife, with every entry, image, and fact sourced from Wikipedia and Wikimedia Commons. The Learn section and blog hold longer articles and guides for readers who want more background than a calculator result gives on its own.

The Honest Version of How the Tools Work

Each calculator uses a published formula or reference range rather than a guess — a size-adjusted dog/cat age curve, gestation lengths by species, standard feed-ration percentages of body weight, and a girth-and-length weight-estimation method used in livestock husbandry. Real animals vary by breed, condition, and individual, so treat every result as an estimate to work from, not a guaranteed figure.
