What does yellow mean?!!!!
She, too, had that white silky hair on her head, that led us to believe she was balding at first.... 
What does the yellow mean?
Edited to ADD: I just checked out some pics...and in three pics, she has something strange going on. One eye yellow, the other blue.........both eyes yellow and green mixed together....and one eye yellow, one eye red!!!!

Remember, you will not get this effect until at least 6 months of age, and don't forget it could be your camera, but these are just general guidelines. For Joey, every picture with any camera that uses a flash produces green eyes, sometimes the shade varies, and looks olive, and sometime almost a lime green, but there's always green when a flash is used. His coat is the dark gunmetal type and is silky, not cottony. As a pup, his eyes looked blue.

What is going on is that those with the gold/bronze cast has LESS eumelanin (black) and more phaomelanin (yellow). Typically phaomelanin (yellow) does NOT get put in the tapetum. So NO tapetal pigment results in red color from the blood vessels. Whereas the blue cast dogs have more eumelanin resulting in a pigmented tapetum and the reflection that you see is bluish or green. It's very similar in chocolate and black Labs-- chocolate labs tend to have pale gold or red tapetums while the black labs have brilliant green and blue tapetums.
Again it has to do with overall production of melanin (pigment) and where it is put. It also has to do with whether the dog carries the genes for true blue, clerical blue or black AND whether they also carry the gene for progressive graying (dilute). That is my explanation I have learned from study of the breed and genes and pigment. - Darinda Tanner. Eye Shine |
