London - A black Labrador who became known as the "rattling dog" had 13 golf balls removed from its stomach after picking up the white balls "like truffles" when taken for walks on a golf course in Scotland, it was reported Friday.

Owner Chris Morrison had been taking five-year-old Oscar round a golf course in Dunfermline, north of Edinburgh, for several months when he became concerned about a rattling sound emanating from the pet's stomach.
