Your dog ate rat poison. Now what?

In case your dog actually DID eat rat bait, I'll skip to the chase: Open his mouth and pour hydrogen peroxide down his throat. About 1/2 cup - 1 cup. Don't worry too much about measuring it out - this is an emergency. Start pouring. He's not going to he happy, but he'll thank you later.
If you caught it early enough, he'll start to vomit small green chunks followed by green ick. The green will gradually turn to yellow then clear as he proceeds to vomit.
If you're not sure how much he ate, or think you might have caught it late you might want to visit your vet in person. Either way CALL YOUR VET and get professional advice. I'm not a vet - I'm just someone who has been through this.
Rat bait is made to be appealing... to more than just rats. Unfortunately, dogs really like this stuff. Be a responsible pet owner and nature lover. Protect all wildlife from harm. Except rats.
Don't let rats watch this.
