If Lexie has dry eye I presume she will now be prescribed lubricating drops indefinitely?
I have a friend who has a dry eye/curly coat cavalier and she recommends a non-prescription ointment called Lacri-Lube. This is very thick and appears to coat the eye for longer than most eye drops.
Grumpy Old William has had ulcers develop in both eyes in the past and, as my vet has said that many dogs develop a degree of dry eye as they get old, I use Lacri-Lube once a day as a preventative measure.
