One of my nephew's Chesapeake Bay Retrievers ate a pair of his wife's panty hose. The exit strategy on that one was hilarious. He was out of town and she called me. Imagine if you will, 100 lb retriever running around the house with a leg of her pantyhose and about a 10 in turd flopping around. Trip to the vet and an insurance claim later, She doesn't drop her pantyhose on the floor no more..
Something similar happened to my first pointer. It was back in the day when women wore stockings. She started taking a dump and about six inches of what looked like her lower intestine started coming our.
