oh, i could tell you stories.... i care for a dog that will eat anything--walked in once to see he had eaten half a bar of soap! i called the vet to find out if there was anything i needed to do. they wanted to know how recently he ate it, and asked me to look in his mouth to see if there was any residue. no residue, but it sure was clean in there! finally, they advised me that the dog would get a "raging case of diarrhea" i wondered if that meant bubbles were going to shoot out his butt???
i had another dog who loved to eat bananas, and yet another who loved celery, and knew every tomato plant in the neighborhood. she loved to snatch and eat the green tomatoes.
