How to identify blocked tear ducts in dogs

1. Tears overflow from one or both sides of the dog's eyelid margins, and traces of brown tears or sticky secretions can be seen under the inner corners of the eyes.
2. Because this part of the skin is soaked with tears for a long time, eczema may occur.

Measures to prevent and treat tear duct obstruction in dogs:

1. For congenital punctal atresia that causes epiphora in dogs, punctal reconstruction surgery can be performed.
2. In order to eliminate foreign bodies or inflammatory products that may exist in the dog's tear duct, use saline containing penicillin for strong tear duct irrigation.
3. For stubborn lacrimal duct stenosis or obstruction, nasolacrimal duct intubation can be performed to permanently expand the narrow part of the lacrimal duct. If the tumor is compressed by the tumor, the tumor must be removed.
