Pet Insulin Dose Calculator

About this calculator

Diabetic dogs and cats are typically started on insulin at a conservative units-per-kilogram dose set by a veterinarian, then adjusted based on blood glucose curves and response over the following weeks. Most protocols split the daily dose into two injections given roughly 12 hours apart — BID (bis in die) dosing — because insulin's effect duration in cats and dogs is usually shorter than 24 hours.

This calculator multiplies your pet's weight by the prescribed units/kg rate and optionally splits the result across two injections, giving a quick number to double-check against what's written on the prescription label. It's meant to support pet owners managing an existing veterinary insulin protocol, not to set or change a dose — always confirm any number here with your veterinarian before injecting.
