Normal dog eyes have small holes
that allow tears to drain down the throat, drainage issues may be caused by;
Atresia of nasolacrimal puncta: a condition where the holes on the inside of the lower eyelids (puncta) are too small, closed
or blocked so tears spill over the lid instead of draining to the nose.
Corneal dystrophy: an abnormality of the cornea usually characterized by shallow pits (eye socket).
Hair growth growing too close to the
Entropion: an abnormal rolling in of the eyelid.
Lacrimal duct atresia: a condition
where the duct draining tears from the eye is too small or not formed.
Breeds More Likely To Have Eye
Discharge And Tear Stains
Any dog, regardless of the breed,
whether purebred or not, can have eye stains. White dogs are more likely
to have visible tear stains on their face because the pigment in their tears
will show up against the white hair as reddish-brown streaks. Dogs with long hair
on their face may also be more prone to excessive tearing because the hair wicks
tears away from the eye and onto the face.
Short-nosed dog breeds, such as Shih
Tzu, Pekingese, Maltese, and Pugs may be more prone to eye staining because they often have shallow
eye sockets or hair growth in the skin folds around their eyes. Cocker
Spaniels and Poodles may be prone to blocked tear ducts.
For Tear-Stained Eyes
Eliminate the source of irritation. This might include keeping hair near the eyes trimmed very short and treating infection, glaucoma, or other eye problems.
Regular washing of your dog's face (use
tearless shampoo) can help, as can eye ointments and antibiotics but avoid
prolonged antibiotic treatment which could lead to
drug-resistant bacteria  which is something far worse than eye stains.
A new product released by CTI Corp eliminates pet eye stains. Dubbed
i StainGon®, the product is 100%
safe and effective.
There are also surgical options for eyelid/eyelash problems which could help
normal tear drainage and eliminate overflow onto the face. Always check with your veterinarian
first but he/she should already know about this non-prescription, inexpensive new treatment.
