Guess the Genotype #78

Can you guess this dog's genotype? Its breed?

This dog is a Podenco Canario, or Canarian warren hound. The breed clearly looks a lot like a smaller version of an Ibizan hound (which, for those who weren't aware, is also known as the Podenco Ibicenco) and both breeds come from Spain. Other than size, one difference between the two breeds is color preference. Most Podenco Canarios have a mostly red coat like this dog, while Ibizans hounds are usually mostly white.

One of the biggest question when looking at this dog is what form of red is it: sable or recessive red? Though the dog is such a dark shade of red and has pigmentation other than black, it's rather difficult to tell. If a dog is sable there is usually some sort of evidence of this. Sables are born with a prominent overlay of dark hairs and dogs who will be clear sables slowly lose that overlay as they grow. When looking at red adult that you haven't seen as a young puppy, there is no way of knowing if this transition took place. The only thing you can do is look for some sort of sign of the sable gene. clear sables will frequently have such things as dark whispers or stray dark hairs on the ear tips or top of the tail. In the case of this dog, if you look closely at its tail you can see what appear to be liver hairs. This would make the dog AyAy sable.

Next, as I mentioned, this dog does not have black pigment. In fact, the Podencos all appear to have breed standards that require "flesh colored noses." Some dogs of these breeds appear to have liver noses, while others have noses that are more pink in color. The pink noses are likely caused by a combination of both the liver and blue genes. In the case of this dog, her nose appears to be liver. This would make her bb liver. Since pink noses are so common in her breed, I also suspect that she's a likely carrier of the blue gene, making her Dd non-blue (carrying blue).

She is also quite a dark shade of red. Going with the theory that red intensity is controlled by the Chinchilla gene, this would make her CC dark red.

Lastly, this dog also has white markings. Namely, she has white on all four paws, the tip of her tail, her nose, and likely on her chest as well. I find it unlikely that this much white is thanks to residual white on a genetically solid dog. Normally, residual white is not this extensive. Instead, I suspect that she is actually a minimal Irish white, making her sisi minimal Irish white.

So, that's AyAy bb CC Dd sisi or dark red clear liver sable with minimal Irish white (carrying blue).

    1. The shadows hide most of them, lol. I might need to talk about these guys one day. I usually know more about the sighthounds/pariahs, but I try to skip around the groups for my "unusual breed" posts.
