No one believed Lt. Col. Percy Fawcett in 1913 when he claimed to have encountered a double nosed dog breed while passing through East Bolivia.
Here we saw for the first and only time a breed of dog known as the Double-Nosed Andean Tiger Hound. The two noses are as cleanly divided as though cut with a knife. About the size of a pointer, it is highly valued for its acute sense of smell and ingenuity in hunting jaguars. It is found only on these plains.

In our Internet connected world, we now know there are real dogs which appear to have two noses. There is no evidence that they can smell better than one-nosed dogs, however. If they cannot smell any better, why are there two-nosed dogs?
TOBY is the sweetest Australian Shepard with TWO NOSES!!! …He was born with two noses and it doesn’t bother him at all. As a matter of fact, it appears to come in handy when he is searching for his old chewed up ball!
Here’s a claim that an entire breed has two noses.
On a trip to Bolivia a few years ago, explorer Colonel John Blashford-Snell met a dog named Xingu who had two noses. You see, Xingu was a rare Double-Nosed Andean Tiger Hound, a breed named for their unusual split (or doubled) nose. … But the truth behind their two-nosed appearance remains a mystery. Despite how it looks and what conquistadors believed, double nosed dogs do not appear to have a superior sense of smell. Well, no more than other canines, that is.
Are there real split nosed breeds?
Three breeds of split-nosed or double-nosed dogs have been identified: the Pachon Navarro, the Catalburun and the double-nosed Andean Tiger hound, even though the split or double nose is mentioned in the breed histories of other European hunting dogs, such as the German Shorthair. The Catalburun is the only breed to require a split nose, probably based on the believe that the double nose increases their scent discrimination abilities. However, no scientific studies exist to support this theory. The Catalburun is considered an independent breed in its home country and is quite uniform in type.
The standard of the Navarro Pointer mentions the occurence of split-nosed dogs, but the double nose is not a sine qua non requirement of the breed. The same goes for the Andean Tiger hound.
Contrary to general belief split-nosed dogs dog not have a higher occurence of cleft palates and hare lips, nor do they show associated morphological, anatomical or physical anomalies as usually seen in cleft-palated and hare-lipped dogs. Purebred Çatalburun or Navarro dogs usually produce split-nosed puppies, whereas parent dogs with hare lips generally have normal puppies.
I prefer to own no dog, but if I was going to have a dog, I’d have a standard one-nosed dog, odds are.
