What happens after my dog drinks hydrogen peroxide?
If she drinks enough for her size she will just vomit. As a matter of fact, we use it a lot in getting a dog or cat to vomit after they’ve eaten something nasty. Sometimes they experience a little irritation and have a lessened appetite for a day or so, and if they don’t vomit after drinking it sometimes they have some loose stool. Don’t panic, if it was a small amount and even if your dog vomits it is normal and nothing scary. Just don’t be surprised if she doesn’t feel too hot for a little while.
