This is kinda gross. Enjoy!

Guy: Hello, Vet Emergency Place, can I help you?
Me: Hi, I have a Shiba Inu. He, um, he ate a tampon. He threw it up a little while ago, but before we could take care of it he...he ate it again. Should we make him throw up again or just wait and see what happens?
Guy: He ate what?
Me: A tampon.
Guy: Oh, hold on just a sec...
~music~
Girl: Hi...so we ate a tampon, huh? A couple times?
Me: Yeah. Should I make him vomit again?
Girl: Well, we don't want that in there. Best to make him vomit. Do you have hydrogen peroxide....?
...etc...

Fortunately, we have peroxide just for this reason. And a turkey baster also just for this reason (if you ever need to force liquid down a dogs throat, a turkey baster is the tool of choice). We've only had to administer peroxide once before, but Kobi got antsy as soon as we opened the bottle. So Annie got to hold him and I got to put him in a headlock and we got to force our dog to vomit. Poor guy was so confused. He thought he was going to get his after-dinner treat, and suddenly we've taken him outside and forced awfulness down his throat and then waited patiently while he barfed up the full contents of his stomach on the lawn. Fortunately, everything came out okay and he was too sick to try and re-eat anything. So he napped all evening on the couch, and I got to clean up and hose down the lawn.
