With Two Noses (S560b)
Tests on the dog proved that it was not a physical malformation but a specific breed of double-nosed dog.
Colonel Blashford-Snell's theory is that the dog is descended from hunting dogs found in Spain at the time of the Conquistadors.
"I think it's highly likely some of these were taken to South America and they've continued to breed," he said.
"They're very good hunting dogs. Xingu was quite an aggressive little chap, about 15" to 16" in height and very friendly with us, and he loves salt biscuits."
"Not a terribly handsome dog, but he's certainly very intelligent," Col. Blashford-Shell added.
Xingu sired two puppies who were born with four noses between them. The puppies unfortunately did not survive.
