River (2 years old) is having really weird symptoms that two different vets can't figure out. Last Wednesday night I noticed that River was holding his third eyelid up on his left eye. By Saturday I took him to the vet who stained his eye and examined him and couldn't find anything. We tried some antibiotic drops with no luck. By Sunday both of his third eyelids were up and his bottom eye lids were drooping so back to the vet. They did the pressures on his eye and really found nothing there either, but wanted to try some steroid eye drops. I have been doing those since last night, but tonight i noticed that his eyes are just the same as yesterday and now he is holding his mouth slightly open as well as if he can't really shut his mouth. I can take him back to the vet, but they just can't find anything. He is acting normal other than the above symptoms. Any thoughts? He has bloodwork done recently, but maybe it is time to do that again? Thanks.
