In January 2016, I took this snapshot of a cute dog waiting by her homeless owner, who was sleeping on a public bench Istanbul's Kadıköy neighbourhood. Just one of the thousand similar scenes you could see in a big city like Istanbul. Nothing unusual, right? Check again.
The dog, against all reason, seemed to have two noses.
I did a double take and returned to photograph the dog. Not only did she have two noses, but the entire front half of her face was duplicated. The left nose was slightly smaller than the right one. Each nose had two independent nostrils, but the nostrils facing the interior side were smaller.
The dog seemed not at all disturbed by this curious deformity. I secretly wondered if her homeless owner had a similarly bifurcated face as well. (He didn't).
The deformity was most likely caused by severe inbreeding, and was rare enough to make the news,   where it was referred to as a “one in a several million” incident.
I and a friend later played a frivolous "credit card machine" joke with this dog.
Alongside one-off sports like these, there are apparently breeds of dogs with a regular occurrence of twin noses. One of these was the spectacularly-named double-nosed Andean tiger hound.
A breed of double-nosed setter dog named çatalburun, (fork-nose,) was also bred in Turkey, near the district of Tarsus, where long ago, and completely unrelated to our story, Paul the Apostle was born. This dog was likely a çatalburun hybrid.
What a strange encounter... People needlessly complain about genetic engineering and GMOs, as if modification of organisms is some blasphemous practice that only started two decades ago. This doggy was a reminder that people have been doing strange things to organisms through selective breeding, for centuries.
