I agree with Bluebells. Dry eye can be one factor. In Max's case, it was trauma. First was conditioner in the bath getting in his eye. Then it was playing with his brother Teddy, paw to the eye. Then it was hair in the eye and rubbing. One thing after another. About 7 months of that before we solved all of the problems.
