I was sitting on the couch last night and I knoticed the dog (5 year old Golden Retriever Maggie May) Anyhow I saw that the pupil of her left eye was sort of glowing red. Like when you shine a light at it. You know how a dog eyes glow with a set of headlights or a flashlight pointed at them. Well, Now I see it again tonight and the left eye isnt doing this and I havent been able to look at it in the day light. I work until dark. I got a flashlight and looked into it and its sort of cloudy. Anyone know what could be wrong and if this is something that needs to be taken care of like today? Thanks.
