Are people saying that sometimes their dogs eyelids droop and sometimes they don't ? Or sometimes they just look droopy and sometimes they don't ? As I said earlier Misty has an unpigmented 3rd eyelid in one eye - but the eyelid is always tight to the eyeball. I'm no expert in this but it sounds strange that an eyelid can just occassionally droop - does that happen ?
All I can say with Lou is if you look at the third photo at the start of this thread, his eyeball fits the shape of his eye, no red shows. However as the day goes on the eye exposed seems greater and there is definate redness around the base and this can show white which sounds a little like ali says in her post above (picture 1).
The eyes do not appear to irritate, Louie is not rubbing at them or seeming to have any discomfort and other than some tearstains this is probably not an issue. I am a little paranoid as Jasper had cherry eye prior to coming to us and that sounded horrendous when the ducts "popped out" so maybe I am looking for problems.
As I have said, he's going back for castration in about a month, so I will keep a check and the vets can look more closely when he's there. Unfortunately it was only the nurse today and, of course, the eye looked fine.
