Interesting, isn’t it? The things we don’t know about our furry sweethearts. You can have two same dog breeds with varying color glowing eyes, even if they have the same eye color during the day. And there’s a biological reason for that.Įvery pup has a different amount of pigment in their retina that can determine the color of their ‘glow.’ Their color can also be determined by age and a few other factors. Well, that doesn’t imply that she has a problem she just ‘glows’ differently. There’s a possibility that one of your pups’ eyes doesn’t seem to glow like the rest. Yes, all dogs’ eyes glow, but they don’t all glow a similar color. But are there dogs whose eyes don’t glow at night? Is it possible? Do All Dogs’ Eyes Glow in the Dark? However, some dogs’ tapetum lucidum lacks pigment, making their glow more like humans’ – red. The ‘glow’ is the excess light being sent out. So, why do dogs’ eyes glow when you take a picture? The film in their eyes – tapetum lucidum – helps them bounce off excess light. They are more reliant on the motion of objects. Nonetheless, that ability comes with a price dogs cannot see as many details as humans. The light that doesn’t get absorbed exits their eyes appear as a glow in pictures, from flashlights, headlights, etc. Light gets reflected outwards, giving your pup’s retina a second chance to absorb the rays. The reflective layer helps dogs, and also cats see better when it’s dark. This particular layer serves as a mirror, bouncing off the light behind their eyes.
On the other hand – just like many other animals – a dog’s retina has a reflective layer behind it known as the tapetum lucidum. This is because the camera flash reflects a blood vessel area behind the retina. In humans, flash photos make our eyes come out devilish red. The difference in the reflection and color is a result of the structure of the eye. The answer is the same for the reason our eyes come out red in night pictures too.
