You can also use "saline" eye solution that contains a moisturizer for dry eye (in the people section) but do not use any that has stuff for contacts or to keep the "red" out. I have used this previously and it helps if used a couple of times per day. We currently have a Japanese spaniel who has degenerative pannis as well as the dry eye so are using the optimmune brand of cyclosporine. It is a gel and does work better than drops, but, it is not cheap. For dry eye, our vet did a test in his office that tested tear production and only cost about $25. I can tell they have dry eye without a test to tell me so. The eye watering and excessive tears is an early symptom of dry eye.
