All calculators

Every PetMathStudio calculator, grouped by the question an owner is actually asking — how much to feed today, whether the weight is on target, how old the dog is in human years, whether something swallowed is dangerous, when the puppies are due. Each one runs the published formulas used in veterinary nutrition references and shows the reasoning underneath the answer. Predictive calcs (age, puppy adult size) render as labeled ranges, not single confident numbers — and the result is a starting point for the vet conversation, not a substitute for it.
