Most dogs beg for treats, but this is a special dog who pays for them himself. Meet Negro, a charming black dog who has been residing on the campus of Colombia’s Diversified Technical Education Institute of Monterrey Casanare for about five years now. He acts as a guardian, watching over things as students study.

The faculty of the school takes care of Negro by providing him with food, drink, attention, and a safe haven to sleep at night. However, it seems that the clever dog has decided to fend for his family himself.
Early on in his time at the school, Negro discovered a shop on campus where students congregated to purchase items during breaks. They would occasionally buy cookies for Negro from there. This is where the dog was first introduced to commerce and chose to give it a shot.

“He’d go to the store and observe the children pay for their items,” said Angela Garcia Bernal, a teacher. “Then one day, out of the blue, he showed up with a leaf in his mouth, wagging his tail and expressing his desire for a cookie.”
Negro had invented his currency, which, of course, was recognized. He was given a cookie, and it was an epiphany.
Since then, Negro has been using leaves to purchase his treats. His “money” certainly grows on trees, as you’d expect. Gladys Barreto, a veteran store employee, said, “He comes for cookies every day. He always pays with a leaf. He buys something every day.”
