Tearing MAY BE due to corneal ulceration of the eyes. Some vets prescribe eye drops but not test for corneal ulcerations. The use of fluorescein stain test showed green corneal areas indicating ulcers.
A fluorescein eye stain test is usually done if your vet suspects your dog has damage on your cornea or foreign objects in his eye. During the test, a dark orange dye called fluorescein is placed onto the cornea (outer surface of your eye). Based on the staining, your vet can identify any problems with your cornea and diagnose certain conditions such as dry eyes. In this Beagle with eye discharge, the cornea is not stained. His cornea is not damaged.

For pet owners, evidence is important to substantiate diagnosis and gain their confidence. Eye discharge for many days would be due to corneal injuries leading to ulcers. Photographic evidence after fluorescein test provides the confirmation.
