Every time I take a new baby to the vet for the first check-up, I ask them to check the eyes for signs of blocked or incomplete naso-lacrimal ducts. That is a fancy name for what we non-vets call tear ducts. They put a dye in the eyes, rinse, turn off the room lights and use a bluelight to see if there is any of the dye from the eye showing in the nostril. If not, that is the reason for tearing in a large majority of the time. There are other reasons as mentioned in the other posts, but not many people know to have this checked. When their dentals and altering are done, the vet can flush the ducts and try to open them. |
