Dog w/heterochromea has red "eye shine" at night in only his partially blue eye

Hello! It’s great that you’re paying close attention to your furry friend’s eyes. Dogs with different colored eyes, like your pup with heterochromia, sometimes have distinct optical features, which can include varying reflections in low light.



The “eye shine” you’re noticing, particularly the red glow in the partially blue eye, is typically caused by the tapetum lucidum. This is a layer in the dog’s eye that reflects light, aiding their night vision. However, if this red reflection is new or more intense, it might be worth exploring further just to rule out other issues.



Common causes for a change like this might include mild irritation, an increase in blood flow, or a change in how light is reflecting off the retina. Ensure your pup’s eyes are free of discharge and check for any signs of discomfort, squinting, or cloudiness.



At home, keep their eyes clean by gently wiping away any debris with a damp, clean cloth.



Keep an eye out for signs like persistent redness, swelling, discharge, or any behavioral changes, as these could indicate a more serious concern such as an eye infection or inflammation.
