Vazquez was stunned.
"I celebrate all dogs, but this one is something very special," he said. "It warmed my heart to see what he does. He does this to everyone who comes to the store."
It's unclear exactly why Cabron started asking for money like this, but some added info gives rise to an interesting possibility. Turns out, the dog was adopted by the woman who runs the shop. She, the controller of the snacks, has presumably learned not to be swayed by Cabron's frequent requests for free handouts from her.
So, seeing that customers are always given food in exchange for money, Cabron, perhaps, realized he could do the same if he could convince people to give him some coins. His shopkeeping owner certainly wouldn't turn away a paying customer, right? Apparently, it's worked well so far.
Whatever the case may be, one thing is for certain — Cabron is a very clever pup.
