I know it's not normal since, like I said before, it was never there before & it does seem to be fading. I've tried to look it up, but didn't find much. Most info I found was about much more serious eye injuries and/or diseases, but I did find out for sure that dogs can bruise their eyes. I'm not too concerned anymore since it does seem to be going away. I just freak out when I think something may be wrong with my baby!
