Meaning and background
The story behind Chaco
Chaco is explicitly recorded as a shorter form of Gran Chaco. Merriam-Webster describes the South American region divided among Argentina, Bolivia and Paraguay and drained by the Paraguay River and western tributaries. That offers a specific geographic association for a dog's name. A particular journey or family link can explain the owner's choice, while this evidence does not automatically connect every other place called Chaco.
