How to Induce Vomiting in Dogs (and Should You?)
By : Trupanion Staff | Updated Mar 28, 2024
Although vomiting will safely bring up most toxins, some will cause more damage by passing through the esophagus a second time than by moving through the GI tract. These include:
- Caustic chemicals, such as bleach and other cleaning products, that can cause chemical burns to sensitive esophageal tissue
- Petroleum-based products that can be aspirated into the lungs during vomiting
Ingested material stays in the stomach for about four hours before moving on to the small intestine. If it has been less than four hours (preferably less than one hour) since ingestion of the toxin, inducing vomiting may be successful; however, if it has been more than four hours, vomiting is less likely to help.
Other instances when vomiting is not a good idea
- Never induce vomiting in a dog that is unresponsive or unconscious.
- Do not cause vomiting if your dog is having a seizure, as he will be unable to protect his airway and could aspirate material into the lungs or choke.
- Don’t induce vomiting if your dog has recently had a seizure, as the stimulation of vomiting may cause another one.
- It is not useful to cause vomiting in a dog that is already vomiting.
Seek veterinary help immediately if you believe your pet has ingested a toxin or if you are not comfortable inducing vomiting at home—ultimately, vomiting is not recommended.
How to induce vomiting in dogs
The only safe home substance that can induce vomiting is 3% hydrogen peroxide. Never use salt, syrup of ipecac, mustard, or other home remedies, and keep in mind there is no guarantee vomiting will remove the toxin.
To induce vomiting in dogs, follow these steps:
- Make sure the peroxide has not expired, because it will only work if it’s bubbly. A fresh bottle will be most effective.
- Load the correct amount of hydrogen peroxide into an oral syringe or turkey baster.
- With your dog sitting or standing, pull back his upper lip and insert the end of the oral syringe or baster into the corner of the mouth.
- Hold your dog’s head upright and slowly push the hydrogen peroxide into his mouth. He should swallow the peroxide as it fills his mouth.
- After the entire amount has been given, walk your dog around the yard to encourage the peroxide’s bubbling action to irritate his stomach and cause vomiting.
- If your dog has not vomited after 15 minutes, give him a second dose of the same amount.
- If your dog does not vomit after two doses, take him to your veterinarian or an emergency veterinarian immediately.
