Convert a prescribed dose per kilogram into a volume or tablet count.
The total daily dose is weight multiplied by the prescribed rate, then divided across the number of administrations. Tablet fractions are shown because many tablets are only scored into halves or quarters. Small errors matter disproportionately in small animals, and some drugs safe for dogs are toxic to cats at any dose, which is why the prescribing veterinarian must specify the drug and rate.
