Milk-Bone is a brand of dog biscuit. It was created in 1908 by the F. H. Bennett Biscuit Company, which operated a bakery on the Lower East Side of New York City. Originally named Maltoid, the biscuit was a bone-shaped treat made from minerals, meat products, and milk. Sometime between 1915 and 1926 the biscuit was simply named "Milk-Bone", owing to the high composition of cow's milk. In 1931 the bakery was acquired by the National Biscuit Company (now Nabisco). The biscuit was the only Bennett product carried over after the acquisition.
Over the next few decades, the Milk-Bone was expanded to include a number of different flavors, such as chicken and beef. The marketing focus was also shifted from Milk-Bone being merely a dog treat to a product that promoted cleaner teeth and better breath. Nabisco, under the ownership of Kraft Foods, sold the Milk-Bone rights over to Del Monte Foods of San Francisco, California, in May 2006.
