CURIOSITY FRIDAY

The pet food industry began with a man watching street dogs eat garbage. In 1860, American salesman James Spratt stood at the London docks, saw strays devouring discarded ship's biscuits — and saw a product.

A TRADE OLDER THAN IT LOOKS

Spratt was in London to sell lightning rods. He left having patented the Meat Fibrine Dog Cake: a baked mix of wheat, beetroot, vegetables and beef blood — arguably the first industrially produced pet food in history. He priced it for the Victorian gentleman's kennel, sponsored dog shows, and effectively invented pet food marketing in the same breath.

1860
Spratt's Patent launches the Meat Fibrine Dog Cake in London — pet food is born.
1907
Rival F.H. Bennett creates bone-shaped biscuits — later famous as Milk-Bone.
1930s
Canned horse-meat dog food booms in the US — the first wet vs dry battle.
1950s
Extrusion technology (borrowed from breakfast cereal) creates modern kibble.
1960s-80s
Science enters the bowl: life-stage nutrition, veterinary diets, global brands.
Today
Freeze-dried raw, insect protein, prescription microbiome diets — and a market measured in hundreds of billions.

The pattern Spratt set never changed: pet food has always sold trust to the human and flavor to the animal. The ingredients evolved — the psychology didn't.

Did you know?

Spratt's early ads claimed his cakes contained 'buffalo meat' hunted on the American prairie. Supply-chain storytelling is as old as the industry itself.

The 4DW Angle

A century and a half later, the raw material behind the romance is still what we trade every week: real animal protein, now with certificates Spratt could not have imagined.

Frequently asked questions

Who invented the first commercial dog food?

American salesman James Spratt invented the first commercial dog food in London in 1860. After watching stray dogs devour discarded ship's biscuits at the docks, he patented the Meat Fibrine Dog Cake — a baked mix of wheat, beetroot, vegetables and beef blood — and effectively invented pet food marketing too.

What was in Spratt's Meat Fibrine Dog Cake?

Spratt's 1860 Meat Fibrine Dog Cake was a baked mix of wheat, beetroot, vegetables and beef blood, priced for the Victorian gentleman's kennel. Its early advertisements even claimed the cakes contained buffalo meat hunted on the American prairie — proof that supply-chain storytelling is as old as the industry itself.

How was modern kibble invented?

Modern kibble emerged in the 1950s, when extrusion technology borrowed from breakfast-cereal making was applied to pet food. Earlier milestones include Spratt's 1860 dog cake, F.H. Bennett's 1907 bone-shaped biscuits that later became Milk-Bone, and the 1930s boom in canned horse-meat dog food in the United States.
