Can I give hydrogen peroxide to induce vomiting?

Dr. Marie replied:

I'm afraid I don't have enough information to fully answer your question. I'm not sure why you are trying to make him vomit.

If you are asking whether the hydrogen peroxide is harmful, the answer is likely no. There is a small risk involved with giving peroxide where it can cause a stomach ulcer if too much is given.

Similarly, if a dog were to aspirate hydrogen peroxide (i.e. inhale it into their lungs) it can cause some serious problems.

Because of these risks I usually don't recommend giving peroxide unless we know that a dog has eaten something dangerous and we need to get it out right away. However, a better alternative is to have your vet induce vomiting with safer medications.

If there was aspiration into the lungs you would likely know right away as there would be breathing problems. If there was stomach ulceration then you may see black tarry stools, vomiting (sometimes coffee grounds color) and lethargy.

You did not mention why you were trying to make him vomit, so if you think he may have eaten something harmful I would highly advise a vet visit.

I hope he is ok!

Dr. Marie.
