with the eye vet..Unfortunately he was in a flare up an eye irritation/infection so I wasn't anticipating a good report..and sure enough he was not producing any tears in his right eye (which has a chronic dry eye problem) ..his left eye (which has never had a problem) was normal...so we've added another drop to schedule for awhile..so we have 4 different drops to get in the eye before work and at lunch...and he gets them even more often in the evening when I am at home and do more...we go back in 2 more months to see how he is doing.
