My dog's eye is changing color and pupil is slighty enlarged.

I have an 8 year old husky mix.(we think)  The vet says she looks like an Akita.  Anyway, she is red and has two piercing blue eyes.  Over the last month I noticed a change in just one of them.  At first I thought her pupil looked enlarged, but only just slightly.  It's not an irregular shape or anything.. just a little bigger, and there have been no changes in her behavior at all.  I didn't think much of it until my Mom noticed too.  So I tried hard to get a better look(if I could hold her still long enough =) holding a treat works.) Now I'm kind of second guessing the enlarged pupil because it's so close in size to the other, BUT the bottom half of her eye looks like it's changing from a light blue to a drak blue.  The eye is not blood shot or anything. ...what in the world?

In case this ever helps someone else, I did take my dog to a doggie opthomologist.  Akiras pupil got even larger after I posted this, so I went ahead and made an appt.  He did NOT think it was cancer(my biggest fear.)  He said that if she had come in stumbling or had further symptoms, he would have considered it and ordered further testing.  Turns out this is a common thing that ONLY happens in blue eyed dogs with age.  That pale blue coloration can be linked to underdevelped eye muscles at birth(the ones that open and close the pupil in the light).. and these weaken with age.  So Akiras doing great FYI- and she will probably always have that dialated pupil for the rest of her life, but at least she is ok!  Hope that helps someone out in the world. =)
