This Dog Uses Leaves To 'Buy' Treats

A clever dog named Negro has grasped the concept of commerce. Negro, who has lived on the campus of Colombia's Diversified Technical Education Institute of Monterrey Casanare for the past five years, has discovered that if he ventures into the campus store with a leaf, in exchange he will receive a cookie.

The Dodo reports reports that Negro is cared for by the school's faculty. They provide shelter, food, water, and tons of love and attention for the pup, who would watch the students in the university shop exchanging money for food and goods until he came to his stunning realization.

"He would go to the store and watch the children give money and receive something in exchange," teacher Angela Garcia Bernal told the news outlet. "Then one day, spontaneous, he appeared with a leaf in his mouth, wagging his tail and letting it be known that he wanted a cookie."

"When you first see it, you almost want to cry," Bernal explained. "He's found a way to make himself understood. He's very intelligent."

Bernal also told The Daily Meal that she was pleased that the dog and the place where Negro lives in Monterrey, Casanare, Colombia, were receiving media attention.
