My poor old girl(13 1/2) suffers from sore eyes, no obvious reason, but she often has the 2nd eyelid halfway up the eye, been to the vets 3 times and they just guess, initially antibiotic cream, then gel for dry eye, then eye drops, they dont seem able to find out what is wrong, but having said that they havent really tried and I wont take her back as its stresses her very very much. The eyes feel warm, and she gets globs of eye mucus in and around her eyes which sometimes stops her seeing where she is going till I clean it off and she does sometimes rub them , but I know even with dry eye they get some form of discharge, would appreciate any ideas suggestions
