I was babysitting my daughter's dogs, a 4lb pomeranian and a 3 lb chihuahua. I woke up one morning and they were both unconscious on the kitchen floor. I thought that they had been poisoned by something, so I poured peroxide down their throats to make them puke. Then I noticed little bits of foil all over the floor, along with my purse. I had gone to a party the night before and someone gave me a brownie wrapped in foil. They were unconscious for about 8 hours, barely breathing. I think the chocolate in the brownie is what really made them sick. I think if they hadn't thrown up they might have died. Not funny!
