I have a female red merle Aussie who just turned a year old. When we got her at 8 weeks, her eyes were grayish. They have since turned a nice amber color, though I have noticed just in recent months on one eye, at the top edge of the iris, a section is turning a pale color. I cant tell if it is turning bluish, or just fading to a white. Could this be a normal color change? I am trying not to worry, and there doesnt seem to be any other problems or discomfort. Any ideas?
I have never known eyes to change that late of an age. I have also never heard of them going lighter. I would have them check out by a doggie eye doctor and have them dialated. Aussies have alot of health problems and PRA is an eye problem that shows up late in life. Usually leading to blindness. I would definatly have it check out.
