Pet Care Master Calculator

This all-in-one tool bundles four separate pet-care calculators behind a single mode selector: pet age, daily food/calorie needs, ideal weight and body condition, and medication dosage. For dogs, the age calculator converts age into human-equivalent years using the tiered formula published by the American Veterinary Medical Association (AVMA) as its guidance for estimating a dog's age in human years -- the first year of life counts for 15 human years, the second year adds 9 more (reaching 24 at age two), and every year after that adds a fixed rate that depends on size (larger dog breeds age faster per year after two, reflecting their shorter typical lifespans); the cat mode reuses the same first-two-year shape with a flat rate for cats. The food calculator starts from resting energy requirement (RER, 70 times body weight in kilograms raised to the power 0.75, a standard veterinary starting formula), applies the standard spay/neuter daily-energy baseline (neutered adult ~1.6x RER, intact adult ~1.8x RER), then scales that by activity level and life stage to estimate daily calories, converting the result into approximate cups of dry food or ounces of wet food using typical caloric-density assumptions. The weight/body condition mode estimates an ideal weight from your pet's current weight and a 1-9 body condition score, where 5 is ideal and each point away scales the ideal-weight estimate by roughly 10% per point (compounding rather than strictly additive), bounded to a plausible range for the breed size you select.

The medication mode looks up a per-kilogram dose for common over-the-counter remedies by weight -- these are commonly cited starting-point reference doses, not a veterinarian's personalized prescription. Aspirin and Pepto-Bismol (bismuth subsalicylate) are unsafe for cats at dog dosing frequencies, since cats lack the liver enzyme needed to metabolize them safely, so selecting Cat with either of those medications suppresses the numeric dose entirely and shows a contraindication warning instead of a number. The hydrogen-peroxide emetic dose is capped at 45 mL (3 tablespoons) regardless of body weight, since exceeding that does not improve effectiveness and raises the risk of complications. None of this substitutes for professional guidance -- always confirm any medication, dose, or frequency with a veterinarian before giving anything to a pet.
