This is Simon...to date he has eaten the following (that I know of) in random order: his own hair, his own poo, a birth control pill (mine), several hair scrunchies (also mine), a book (roommate's), part of a lipstick (mine again) and about 4 pounds of toilet paper...this has resulted in no less than 4 trips to the vet for x-rays all to reveal excess gas in the intestines...I now know the inside of my dog as least as well as the outside.
The diagnosis from the vet? Simon has a sensitive stomach... Lesson Learned?...eating toilet paper causes bad gas...
