OMG! This was hilarious! It's so enjoyable when it happens to someone else (my Jack Russell is a kitchen dispose-all).

My sister has a story of her pup, a sheltie, who would eat ANYTHING. One day she looks over and sees something hanging out of her backside. It's a string. Yes, the pup had eaten a tampon and it was working its way, undigested, through the system! UGG!!!
