After the 5 week mark, that’s probably their permanent eye color… but I have heard of Huskies changing eye color even later. They can even change their eye color as late as 4 to 5 weeks old. Yes, when they first open their eyes, at around 2 weeks old, all Siberian Huskies appear to have blue eyes. Siberian Husky puppies’ eye color may change As a correlation, think about the sky – it looks blue but outer space is not blue. It’s about the way light enters and exits the eye, thus creating that blue nuance. Just to be clear: there is no blue pigment in the eye. So now you know the scientific explanation of those lovable eyes. The mutation of the aforementioned ALX4 gene leads to a decreased pigment production in the eye – this makes them appear blue. (apart from humans, where blue eyes are caused by a genetic variation of genes called HERC2 and OCA2) In this study, they found out that a genetic mutation near a gene known as ALX4 on canine chromosome 18 is tied to those amazing blue eyes in Siberian Huskies. (to identify their dog’s breed and eventual health issues) The researchers tested the DNA of more than 6000 dogs whose owners purchased DNA test kits. They published a study here, in the PLOS Genetics journal by Adam Boyko and Aaron Sams of Embark Veterinary, Inc. So at a DNA testing startup, they set out to explore this question by looking at possible causes that might cause blue eye color in dogs.Īnd they found some info! In what is probably the largest study to ever compare dogs’ complete genetic profiles, they found a genetic tweak that can cause blue-eyed dogs. Huskies and other dog breeds with blue eyes have even fascinated scientists. I’m quite amazed that my Husky lady is parti eyed, as her right eye has some blue shades while the majority of the eye is brown. They look amazing and somewhat freakishly. Parti eyed means that one of the eyes has two shades of coloring in them: blue & brown. This is indeed rare and one of the rarest variations in Husky eye coloring. My Husky Lady is also Parti Eyed Parti or Split eyed
