How To Induce Vomiting In A Dog

Dog vomiting

If you suspect that your dog has swallowed something harmful (such as antifreeze), if possible call a vet immediately.

Your vet may tell you to make your dog vomit, in order to limit the amount of any toxic substance that is absorbed into the body.

Before inducing vomiting

If not certain, call your vet or the poison control center (info at bottom of page). There are quite a few substances, that if swallowed and then a dog is made to vomit, can make the situation worse.

Do NOT induce vomiting in the following circumstances, unless instructed to do so by a vet.

  • Dog has swallowed an acid or alkali (caustic)
  • Dog has swallowed a petroleum-based product
  • Dog has swallowed a household chemical including cleaning products
  • Label on container of substance swallowed says, “Do not induce vomiting”.
  • Dog has already vomited
  • Dog has swallowed a sharp object
  • Dog is too sleepy, uncoordinated, or impaired in some way, including having had a seizure, to be able to safely vomit. If a dog inhales vomit in the lungs they are at a high risk of developing aspiration pneumonia.
     

Use 3% hydrogen peroxide to induce vomiting

Make sure that the hydrogen peroxide is the standard drugstore concentration of 3%.

Give your dog 1 tsp (5 ml) per 10 lbs of body weight. This is 0.5 ml per lb. So a 60 lb dog would get 6 tsp or 30 ml.

How to give hydrogen peroxide

If you have syringe (without a needle) or (clean) eyedropper, squirt bottle or even a turkey baster, this is the easiest way to get your dog to swallow fluid.

  • Put one hand under the dogs muzzle with fingers on one side and thumb coming up the other side.
  • On one side insert the syringe between the back teeth and cheek in the cheek pouch with the end of the syringe pointing in the throat direction.
  • Hold the lips together and tip dogs head back slightly. Start gently squirting the fluid
  • Depending on volume, pause one or more times to give dog time to swallow
     

If you do not have a syringe or anything else suitable for squirting in the cheek pouch, put the hydrogen peroxide directly into the dog’s mouth.

It is probably worthwhile, before you need it, to get something suitable for squirting in the dogs mouth. Measure out the appropriate amount of water, suck it up into the turkey baster or whatever you will use and make a mark with a Sharpie at the correct level. Then if you do need to make your dog vomit quickly, you will not waste time figuring out the volume required.

After giving hydrogen peroxide

Vomiting can occur anywhere from almost immediately to 15 to 20 minutes after giving the hydrogen peroxide.

To help promote vomiting, if possible, after giving the hydrogen peroxide make the dog walk around a bit. If not possible briefly jiggle the stomach area around.

If the dog does not vomit within about 15 to 20 minutes, repeat again up to 3 times in total. If the dog still does not vomit, take the dog to the vet, if you are not already doing so.
