well, defianetly see a specialist first, and see what he says, before doing anything drastic like taking her eye out. but in general i agree. if she cant see out of it anyways, might as well... although i'd do a bit of research on it. see if there's any downsides to it... who knows...
i know there's someone here with a one-eye dog... if only i could remember who it was.... maybe they can give you some advice... hm....
