It can be a cause for concern if you notice your dog begin to vomit but it is necessary if your dog has ingested items or substances that it should have in order to protect its body from harm. Vomiting is a natural response by your dog's body to remove unwanted materials it is also a reaction to many illnesses.

Even if your dog is in perfect health it could suddenly become ill and begin vomiting. There are many reasons why this could happen.

Your vet will need all information you have about what you've seen your dog do in order to diagnose a treat your pup effectively. 

A Note on Inducing Vomiting in Dogs

Toxins can cause serious damage and gastrointestinal upset and so you may be informed that the ideal thing to do is induce vomiting. The goal is to eliminate the toxin from the body before it’s absorbed. If vomiting occurs before the intestines absorb the toxin, toxicity can be prevented. There is a risk with any caustic substances burning the esophagus while passing through a second time while inducing vomiting. 

Unless in extreme circumstances, inducing vomiting at home is not recommended by any vet. Inducing vomiting should always be done by a licensed veterinarian and you should call your vet and speak with them before ever attempting this solution. 

Typically whatever substance your dog has ingested won't be toxic so the chance inducing vomiting at home would be necessary is low. 

Also, if 3% hydrogen peroxide (the only safe home substance that can be used to induce vomiting in dogs) is incorrectly administered, it can enter the lungs and cause significant problems such as pneumonia. 

If it's needed, having a qualified veterinarian induce vomiting in-clinic is recommended, especially with dogs who have underlying health conditions or other symptoms. 

When Not to Induce Vomiting

Under no circumstances should you induce vomiting in a dog that is:

  • Having a seizure or recently had a seizure
  • Lethargic
  • Unresponsive or unconscious
  • Already vomiting

Additionally, hydrogen peroxide should never be used as a way of inducing vomiting in cats. If you have a cat in distress place contact your Animal Emergency Clinic vet right away.

What do veterinarians do to induce vomiting?

At Animal Emergency Clinic, we thoroughly examine and diagnose in order to determine the appropriate action to take. If inducing vomiting is the best treatment option then special medication with minimal side effects is used (as opposed to hydrogen peroxide). If your dog does experience any side effects, we are equipped to administer proper care and medication.

What should I do if I suspect my dog has ingested a toxin?
