The first dog biscuits did not resemble the bone-shaped delights of today. Developed by James Spratt in 1860, these so-called Meat Fibrine Dog Cakes were woefully square.
Spratt, an American electrician, came up with the idea for a dog biscuit after he witnessed sailors dropping hardtack—an unleavened bread—for the local dogs.
He decided he could do the same—and monetize it. His flagship company, Spratt’s, was founded soon after. Their lead product, the Meat Fibrine Dog Cakes, were developed from a combination of wheat, beetroot, vegetables, and prairie meat. (The particular kind of meat in Spratt’s formula was apparently highly confidential; until his death, Spratt “kept in his hands the contract for his meat supplier.”)At the time, the concept of a food specifically for dogs was alien. According to Katherine C. Grier, author of Pets in America, “until well into the 20th century, most household dogs lived off scraps from the kitchen, often cooked with a starch into something that people called ‘dog stew.’” But by the late 1800s, Spratt’s had shuttled dog biscuits into the mainstream—especially for dog show contestants. In 1895, the New York Times labeled Spratt’s a “principal food” of dog shows.
Spratt’s success soon spawned competition.

Over a decade later, in 1907, organic chemist Carleton Ellis received an urgent request. The owner of a local slaughterhouse was having problems with all of his excess “waste milk,” and he wanted Ellis to help him find a use for it. Ellis would eventually accrue over 753 inventions to his name and would serve as the force behind the creation of margarine, polyester, paint and varnish remover, and anti-knock gasoline.
If he found the milk request odd, he did not show it. He agreed to…The post How an Organic Chemist Invented the Bone-Shaped Dog Treat appeared first on FeedBox.
