Making your dog throw up isn't a pleasant task. If he has eaten something poisonous, however, it can make a big difference in his chance for a full recovery. If you suspect your dog has been poisoned, before making him vomit, contact your veterinarian or the 24 hour Pet Poison Helpline (800-213-6680) or ASPCA Hotline (888-426-4435) right away.

How to Induce Vomiting Using Hydrogen Peroxide

Since your dog will be vomiting, it's a good idea to do this process on a floor surface that's easy to clean, such as kitchen or bathroom tile. Alternatively, lay some newspaper or plastic bags on the floor to capture the vomit and protect your flooring. Also, be sure to ask your veterinarian if they need you to catch a sample of the dog's vomit so you can be prepared with a container. Depending on the substance, the vet may want you to do this although not always.


You'll need the following materials.

  • 3 percent hydrogen peroxide solution: It should be relatively fresh and not flat from sitting in your cupboard for years.
  • Some food if the dog hasn't eaten recently although this is not required: Adding some food just prior to using they hydrogen peroxide can sometimes make it more likely your dog will vomit.
  • A dosing syringe or turkey baster


Do the following:

  1. Use the syringe and draw about one milliliter of hydrogen peroxide per pound to a maximum of 45 milliliters. In other words, if your dog is 40 pounds, draw 40 milliliters. If your dog is 60 pounds, draw 45 milliliters.
  2. Gently squirt the hydrogen peroxide into the back of your dog's mouth and then wait.
  3. If after 15 minutes your dog has not vomited, you can give him one more squirt of the hydrogen peroxide but no more after this.


If you are having trouble getting your dog to hold still to squirt the hydrogen peroxide, a trick you can use is to pour it into a bowl and then place some pieces of white bread in the bowl to soak it up. Then feed the bread to the dog.

Be careful about cleanup if the dog has ingested anything that might be harmful to you. You can use rubber gloves to be safe.

Dogs and Toxic Substances

There are many items inside and outside of your home that can be dangerous to your dog if ingested. Common household items include certain foods like chocolate and onions, household cleaners, medications, and indoor plants. Likewise, your dog is at risk from substances outside the house, such as toxic plants and trees, and chemicals in your shed or garage such as antifreeze and insect repellants.

Once you've spoken to a veterinarian, they will most likely ask you to get your dog to vomit right away to reduce the chances for the poison to do damage to your dog's system. Do not attempt to make your dog vomit without speaking to a medical professional first as there are certain substances where doing this will cause more harm than good. Corrosive and acidic substances such as drain cleaners and items with gasoline or oil in them should not lead to inducing vomiting. Instead, get your dog to the veterinarian immediately and follow his or her instructions.

Helping Your Dog Throw Up

Vomiting is never fun whether you're a dog or a person. In an emergency, knowing how to help your canine best friend throw up can be a lifesaver. A smart pet owner should always keep a bottle of hydrogen peroxide in their medicine cabinet and replace it regularly so it stays effective if a poisoning situation with your dog ever occurs.
