Ask your vet first
Ondansetron is used in dogs, but dosing decisions belong to your veterinarian. Prescription anti-nausea medication. Vets choose it for specific causes of vomiting; suppressing vomiting without a diagnosis can hide an obstruction or toxin that needs treatment.

About Ondansetron

Ondansetron is a prescription medication, dosed by your veterinarian for a specific diagnosis. You will see it sold as Zofran, and the label strength on the box is what matters for the math, not the brand. Reference data on this page reflects published veterinary sources, not a prescription for your dog.

What to have ready when you call the vet

Whether you are confirming a dose or reporting that your dog already got into something, the call goes faster with four facts ready: your dog's current weight, the exact product name and strength from the label, how much was given or eaten, and roughly when. With those, most clinics can answer in one call.

The safe habit

Confirm any medication decision with your veterinarian, who knows your dog's health history and other medications. VetDose shows published reference data, not prescriptions.
