Thank you for transferring to this site; it just means that I can't change my answers later and pretend I said something else; apparently this is important for holding us accountable. On Facebook, you posted a picture of a dog with scelerae (eye whites) that looked almost red (frustratingly I can't find it now). It may have been 'episcleral injection,' where the blood vessels in the eye become inflamed and dilated and visible. This can be secondary to glaucoma, for example. Another cause of red-eye concerns a dogs' ability to clot their blood. Blood clotting problems can be a sign of Angiostrongylus Vasorum, or "lung-worm" - as can coughing, so it's worth asking your vet whether this is something that's worth ruling out. Trauma may also be on the list, but I would have expected it to be quite intense to have caused this - it's worth asking what might have happened to have caused that. Direct trauma to the eyes would normally have been extremely painful. Various different (to lungworm) blood-clotting problems e.g. secondary to liver problems, may also be up for discussion, as might tumours. I also wonder about very high blood pressure. I hope that something there is helpful - your vet may already have ruled some of these things out. If your dog's condition is deteriorating, it may be an emergency so please consider calling the emergency vets.
