My pup (almost 11 weeks) had a weird thing with her eye when I woke up. Sometimes, it rolls back just slightly, so it looks like half the eye is white and half is color. It is only happening in one eye. It's happened 3-4 times throughout the day then it goes back to normal. I think it could have got swatted by a cat, during a quick time when I wasn't looking, or maybe she bumped her head wrong while romping around? What do you all think?
