My dog has addisons disease and is having a reaction (I think) to his meds and his eyes keep running and when the light hits his eyes he squints like it hurts him. So I thought that maybe it was causing dry eye.
Human medication should not be administered without the permission or advice from your veterinarian who knows your dog's full health history, but my veterinarian recommends the use of eye drops for dry eyes every 1-4 hours as needed until an examination can be performed. The contact relief with these are very short thus the timing of every 1-4 hours depending on the severity. I have included some information below about eye drops in dogs that I feel will be of help to you. I do advise a simple call to your veterinarian as to their preference on this practice.
Most artificial tear solutions contain preservatives but some are preservative-free. It is believed that preservative-free solutions may be milder and cause less irritation of the cornea, particularly with long-term administration.
Artificial tear solutions are not approved for use in animals, but they can be used in an extra-label manner.
