The chocolate chip cookie was invented by Ruth Graves Wakefield. She owned the Toll House Inn, in Whitman, Massachusetts, a very popular restaurant that featured home cooking in the 1930s. Her cookbook, Toll House Tried and True Recipes, was first published in 1936 by M. Barrows & Company, New York.
Like humans, dogs have two sets of teeth in their lives. The 28 baby teeth erupt through the gums between the third and sixth weeks of age. Puppies do not have to grind much food, so they do not have molars. Puppy teeth begin to shed and be replaced by permanent adult teeth at about four months of age.
