Peewee is now 10 months old been to two vets and specialist nothing to due but keep the eye moist she gave him Opitimmune, which caused peewee to always close his eye so it irritated the eye, stopped using it then I went and bought over the counter a rinse to flush out the matter then I started using GenTeal Lubricant eye gel for severe dry eye worked great both twice a day. Now it has stopped working, his eye seems dry more often. Any one have this problem with their dog? What do u use??
