This reminds me of the time Shaggy was discovered to have a gum wrapper in his "Droppings"! He was over at his "Girlfriend's" house and her owner discovered it! We laughed so hard. I am glad he was okay. It was just funny!
The funniest story isn't about my dog but my brother... When he was a baby my mother was changing his diaper. She found a tag in his doo-doo. The tag said: "Made in Tawain". My mother then had to start questioning who the "real" father was!!!!
Anyways, the next time you suspect your dog or cat of eating something poisonous or harmful there is a way to make them throw up. Give them a teaspoon (depending on weight) of hydrogen peroxide. The same stuff used in toothpaste and used in treating cuts. This will produce vomitting in about 10 minutes. Don't over do it. It can be dangerous and should ONLY be used in emergency.
Scooby ate a plate full of chocolate chip cookies while I was talking to a neighbor. I had overloaded the cookies with chocolate chips because they were for me! I gave him about a teaspoon and a half. Within 10 minutes they came up. I recommend doing this outside! They can eat grass AFTERWARD! I promise the dog/cat will hate it but they will spit it up!
