chin with weepy eye

Dec 19, 2015
I've been taking one of my chins to the vet over the last 3 weeks for a weepy eye. She's had xrays that show no tooth problems. Metacam for 10 days and now ocufen for just over a week. There's not much change in her condition.
I've been searching online and see that ocufen can be painful so not feeling comfortable continuing to give it to her. I see the vet again Tuesday. A breeder on a facebook page has recommended lubrithal as a good go-to for general chin eye problems. Does anyone have experience of that? Vet is an exotic but doesn't know what's causing the problem. TIA
