In 1860, James Spratt, an American Cincinnati electrician, went to London to promote lightning rods. When the ship arrived in England, he accidentally discovered that his beloved dog particularly enjoyed eating cookies discarded by sailors. So, with a sudden inspiration, he quickly brought flour, vegetables, meat and water, mixed them together, and began to manufacture and sell dog food. The first commercial dog food in human history was born in this way.
After 62 years, in 1922 in the 20th century, Chappel Brothers not only provided canned horse meat to refugees from countries such as France, the Netherlands, and Italy, but also used the remaining meat as dog food and returned it to the United States. During its heyday, the company could slaughter up to 50000 horses per year.
In 1954, an American company tried to mix Rice noodles, salt and sugar with emulsified animal liver, skimmed milk, soybean powder and other raw materials, stir and mix them into paste, and then dry them on asphalt ground. The imitation taste is similar to popcorn and is loved by pet dogs.
In 1957, Americans applied the puffing process in food to pet food, and the world's first puffed dog food bag was introduced. From then on, pet food produced through puffing technology has occupied the main position of pet food due to its absolute advantages of comprehensive and balanced nutrition, convenient feeding, and time-saving. Thirty years later, in 1987, the amount of dog food sold in supermarkets alone in the United States reached $2.7 billion, with a sales volume of 2.64 million tons.
