If I remember correctly, dry eye can only be treated properly with the use of "Optimmune" a special eye ointmant for the condition. I remember it being really expensive, but it should last you quite some time if used properly. I know some people that use sterile saline to rinse the eyes on occasion, but the ointmant is needed to help prevent blindness and ulcers from forming, so don't stop using it! This condition is very common in cockers, lhasas, shi tzus, and pugs...
