After watching people use money to buy food, a clever dog figured out his own way to pay, with leaves.
In Monterrey, Colombia, a black dog named Negro lived on a school campus and often watched students buy cookies at the shop.

One day, he picked up a leaf, walked to the counter, and offered it like money.
The staff played along and gave him a cookie. From that day on, Negro started “buying” cookies with leaves every day.

They limited his treats to keep him healthy, but his adorable habit quickly went viral around the world.
Proof that dogs are not just loyal, they’re also smarter than we think.
