A clever dog living on campus at Colombia’s Diversified Technical Education Institute of Monterrey, Casanare has invented his own form of currency, and goes to the corner store every day to “buy” snacks using a leaf that he has retrieved.
The observant black dog, named Negro, has lived on the campus for the last five years, where he is lovingly taken care of by the faculty. During his down time, he has obviously been watching commerce in action at the small store.
“He would go to the store and watch the children give money and receive something in exchange,” said teacher Angela Garcia Bernal. “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.”

Since first discovering that leaves can “buy” treats, Negro has been a daily visitor to the store to purchase his favorite cookies. One leaf buys one treat. Staff ensure they only fed him dog-friendly snacks, and don’t let him do his shopping more than two times a day, to keep him from over indulging.
“When you first see it, you almost want to cry,” Bernal said. “He’s found a way to make himself understood. He’s very intelligent.

This is so sweet. Thank you for being so kind and loving to him.
Awwwwww, so cute, they are so intelligent one has to wonder whether they are more intelligent than their human counterparts…..in the wild, the wolves only allow the alpha female to have pups, and the other females are driven out of the pack when they come into season, as the wolves know the pack can only support one litter of pups per season…..so what has happened to the humans without jobs or income that have one baby after another!!!!!!!! it Maes one wonder.
Awww! Negro is super cute. I’ll never stop to say that animals are so much more intelligents, lovely, kind, respectful creatures and we have too much to learn from them
🙂
Very special!
God bless him.
Negro. And no one is offended? WOW.
stupidness uneducate MORONS who comment on his name Negro. This is a SPANISH WORD USED IN A SANISH-SPEAKING COUNTRY, it means Black. God, please get rid of all human idiots roaming the Earth, it’ll reduce global warming. Animals are so much more intelligent and loving. If you find the use of a word invented many centuries ago you really need to crawl under a rock and disappear.
Oh how cute.
My folks live in Colombia and recently saved a poor mixed breed pup who was almost hit by a car in traffic… right in front of where they were standing. My mom saved her.. took her to a vet had her bathed and she’s now part of our family.
ANIMALS ARE AWESOME. THIS BEAUTIFUL FURBABY IS SO INTELLIGENT. ALL ANIMALS HAVE A BRAIN AND A HEART.
Dogs continue to amaze me. So adorable
Bright Boy.
‘two times’ ? There’s a word for that = TWICE.
That is your comment?! Reporting on the use of “two times” instead of saying “twice”? What are you? word cop? This is a great story and I am so happy to hear good news for a change.
Oh my gosh, what a darling! I would make special treats just for this guy 🙂
Awesome! So precious. All dogs can learn new tricks for sure.
This uplifting story has made my day! Smart dog. Smart people. Good match.
Negro is not offensive in Latin Countries. Negro or Negrito is a nickname and is not offensive. and the snacks are dog snacks.
Brought tears to my eyes – bless him!
What a smart and sweet baby. Animals are extremely intelligent and loving. I am happy we have animals on this Earth. I only wish everybody would treat them with the kindness, love and respect they deserve. All beings have feelings, that includes animals as well as people.
How adorable is this? And how clever is this dog?
Extra cuddles – and the occasional extra snack for him I think xxxxxx
If you would read they only give dog friendly treats not regular cookies
They are wonderful.
A cookie a day is not a good idea. Please feed the dog something healthy.
Beautiful story. Shame about the name ‘Negro’ which is still seen as offensive by some.
Too bad for them. Are we going to be expected to remove the word ‘black’ from the English vocabulary?
No, it is not “too bad for them” because it is a Spanish word that describes the look of the dog. It is not derogatory in any way and therefore not offensive but it’s all in how the word is used. This is just a cute story about a black lab dog doing this funny thing to get his daily biscuits.
negro is spanish for the color black. the e sound is lower case.
What a smart and observant dog he is. Bravo!! ????
Thank you for sharing Negro’s cleverness. He is a lucky dog to be surrounded by those who love him.
What a beautiful story of A very beautiful clever dog. It’s wonderful to see how well he is treated by the staff and people on campus. I wish all of humanity was so good to animals. A touching story. ❤️
A great leaf looks like green paper money too! Could he be that smart to see the resemblance?
This is so compelling! My Scottie used to bring me his leash whenever he wanted to walk and he always then dragged me in the direction of a great 2nd had bookstore in the McGill Ghetto called “The Word” where the owners always gave him a cookie. But exchange? Wow. Negro is one smart cookie! (Pun not really intended). I make cookies for dogs with a bone shaped cutter. If I had the exact address I’d try to send them some.
This is soooo precious!
Thank you for taking in & caring for this sweet, wonderful, intelligent dog!!
How lucky he is to have friends watching over him. I’m sure he gives away a ton of love in return!!
Loved the story
How cute, who says animals are smart.love this story.
That is so sweet glad he’s getting cared for by the faculty
I’m glad Negri has good life and well taken care of. He learn quickly.
Animals are the most intelligent creatures on earth!
Beautiful — thank you — thank you for taking care of this sweet, innocent, vulnerable dog — are they DOG biscuits? — Or, are they PEOPLE biscuits? — remember, the sugar may not be so healthy.
