Four tools, one prescribing workflow

Most vets juggle a formulary, a calculator, a prescription pad and a textbook. VetDose folds all four into one connected workspace — what you calculate flows straight into the prescription.

Dose Calculator

Exact mg and volume for this patient, with the clinical context to back the call.

Prescription Builder

Turn any calculation into a branded, signed, printable prescription in under a minute.

VetDDx

Enter a presenting sign and get the ranked differentials, each with clinical guidance.

Clinical Workspace

Your clinic, team, patients and full case history, kept together and private.

Small-animal focus

Built for dog & cat practice — every tool

Not just doses. The calculator, prescription builder, VetDDx differentials and clinic records are all tuned for the dog and cat patients in front of you.

Species-specific dosing

Separate indications, dose ranges and routes for dogs and cats — no one-size-fits-all.

VetDDx for dogs & cats

330+ differentials across 45 signs, ranked for dog and cat cases with cited tests.

Cat-aware safety

Per-animal fixed doses for cats that aren't weight-based, with feline warnings flagged.

Dog & cat knowledge base

150+ drugs and 330+ differentials, reviewed against the standard veterinary references.

Beyond mg/kg

The calculations you reach for the manual for

Ten dosing modes and 30+ routes — including the specialist maths most vet apps skip.

CRI infusions

µg/kg/min and mg/kg/hr modes output the infusion rate, pump rate in mL/hr and the 24-hour total volume.

BSA chemotherapy

mg/m² dosing via the Meeh formula with multi-protocol tables — usually a specialist-only feature.

Guided reconstitution

Enter vial mg and diluent mL and it gives the concentration, then the volume to draw.

Per-animal fixed doses

Some drugs aren't weight-based — VetDose knows which, and gives the correct fixed dose.
