How to Make Your Dog Vomit Using Hydrogen Peroxide

How to Make Your Dog Vomit Using Hydrogen Peroxide:

This is something that might come in handy if your dog eats someone's sock, or some of those brownies you left cooling on the kitchen table.

Induction of vomiting is best done within 1 hour of your dog eating the inappropriate thing. That being said, do not induce vomiting if you think the object/substance could do more damage on the way back up (e.g. sharp objects, caustic chemicals, etc.). If in doubt, please talk to your veterinarian.

Hydrogen peroxide can cause stomach irritation, and can also cause prolonged vomiting (i.e. more than we want, which can be unpleasant for your pooch) and for those reasons we always suggest having your veterinarian induce vomiting as the better option - they use a drug called Apomorphine that doesn't have these same side effects. That being said, if you're in a pinch and can't get to the vet, try the following:

  • Use a 3% hydrogen peroxide solution, which is widely available over-the-counter in most pharmacies.
  • Measure out 2.2 mL / KG of body weight. Do not exceed a maximum dose of 50 mL, regardless of body weight. See below for some common dose amounts.
  • Get your dog to ingest the hydrogen peroxide liquid - the best way to do this is to mix it with a bit of food.
  • Often they will vomit within a few minutes. If there is no success, you can repeat the same dose once more 10–15 min later, but do not repeat a third time.

Common dosing amounts:
5 kg = 11 mL
10 kg = 22 mL
20 kg = 44 mL
30 kg = 50 mL (max)
40 kg = 50 mL (max)
