Hmmm, I don't know, I just really paided attention to it when I was taking their Christmas pics, so many of them Bailey's had the greenish/yellow eye glow. Jesse had zero glow, and Jesse's coat is like pure silk, very strange.
Just wanted to add, I knew about the eye shine in yorkies, the Green = Silky...Red = Cotton, I just thought it was unsual that Jesse had no eye shine in his pics
