What is Boirque?

Boirque was the name of the long-deceased dog of my also long-deceased grand-uncle.
He was an half-wild dog who spent most of his days in the jungle near to my grand-uncle's little farm, hunting.

I and my brothers used to amuse ourselves during our childhood holidays in Minas Gerais' country-side (BR) by feeding Boirque whole raw eggs, which he ate with much pleasure, breaking them inside his mouth.

I liked the dog and I like his name, which has no meaning in Portuguese, but might mean something in ancient Tupi-Guarani (the language of the once largest Brazilian Native tribe) or some African language.

In its after life, Boirque lends his name to my blog.
