Milk Bone dog biscuits are made from wheat flour, bran, meat bone meal and beef fat. They also contain milk and added vitamins and minerals. The original name of the treat came from the high percentage of milk products in the original recipe.
There are a number of different varieties of Milk Bones made to suit the needs of different breeds of dogs. In addition to the three sizes of Milk Bones, the company also produces a line of lower-calorie treats for overweight dogs. The company also produces Brushing Chews, a biscuit with added abrasives to help clean a dog's teeth while he chews. Milk Bone also produces a variety of crunchy and chewy treats alongside its signature dog biscuits.
Milk Bones are a baked product, made from a relatively dry batter that produces a dense, hard biscuit when cooled. Standard Milk Bones come in five flavors, including beef, chicken, bacon, sausage and turkey. The company also produces Gravy Bones, which are basted with a surface coating, and come in beef, bacon, chicken and liver varieties.
Milk Bones were invented in 1908 by the F.H. Bennett Biscuit Company, and were the first mass-produced dog biscuit treat made in the United States. In 1931, the company was bought by Nabisco, and Milk Bones were the only product carried over to the new ownership.
