How Do I Make My Dog Throw Up?

If it has been awhile since this has happened you should call animal poison control to ask for their advice.  They will tell you how much of a certain substance a dog can take in their system and be ok and whether or not you should still induce vomiting.

If this is something you catch immediately, you pour a small amount of hydrogen peroxide down his throat.  This takes a bit of wrestling.  You will probably need to stand over your dog and force the mouth open.  Then you wait for the dog to throw up whatever harmful substance he has ingested.  It is not pretty - they will gag, and convulse a little as it bubbles in their tummy.  I usually keep my dog on a leash so that he can't go back to lick it up and then I wipe it up immediately with a paper towel.  This is what my vet told me to do.   

IF YOUR DOG HAS SWALLOWED AN OBJECT OR ABRASIVE SUBSTANCE, DO NOT DO THIS AS IT WILL DAMAGE THE ESOPHAGUS.  YOU SHOULD CALL A 24 HOUR VET AND ASK THEM WHAT TO DO - YOU MAY NEED TO BRING YOUR DOG IN.

If you must induce vomiting, what you do is... Have someone on the dog as sternly as they can, keep the head up, while someone else pours peroxide into his mouth. Make sure he swallow it, wait about a min, and do again, if he has any protein or anything in his tummy that he shouldn't have it will start to fuzz and he will throw up. Sounds crazy? It works! Trust me.
Toast, not funny...

Sometimes if a dog eats something it shouldn't, it is advised for the dog to get rid of it in some way, but most Vets prefer to use laxitives instead of making the dog throw up.

Make sure you aren't wanting to make him throw up something that will do more harm having it come back up.

You can give him a tsp of Peroxide to force him to throw up.

Why would you want to do this? I don't understand it. If there is something that is bothering your pup, you should either call the vet or take the pup in. Hope this helps, good luck to you and the pup.
