In 1860, an electrician from Ohio named James Spratt arrived in London, England to sell lightning rods. While in London, he saw a throng of dogs feed on hardtack and decided to make biscuits that dogs could eat as a primary source of food. He called his biscuits “Spratt’s Patented Meat Fibrine Dog Cakes” and sold them to rich English gentleman. Eventually, he was able to expand his business to the US and his biscuits became a must in dog shows. In 1907, inventor Carleton Ellis turned the biscuits into the iconic bone shape. A year later, F. H. Bennett Biscuit Company released the bone-shaped biscuits that today we know as Milk-Bones.
After WWII, dog food become more commercialized and it’s now an industry with profits of $15 billion per year.
