Common Breeds Prone to Dog and Cat Tear Stains

Poodle, American Cocker Spaniel, Maltese, Samoyed, and Shih Tzu

These breeds often suffer from tear stains due to the long fur around their eyes, which can irritate the cornea.

Himalayan Cat, Persian Cat, and Persian Kitten

These feline friends are more susceptible to tear stains because of their shorter nasal tear ducts.

What Causes Cat and Dog Tear Stains?

The principle behind the formation of tear stains may be that porphyrin, excreted through tears, reacts with the hair where tears linger, turning it a rustcolored stain.

Yeast infections around the eye corners can also lead to tear stains.

(1) Excessive Tear Production

Stimulation or pain in the cornea can lead to an increase in tear production.

(2) Obstruction in Tear Drainage

When tears do not follow the normal ducts, they can overflow, causing stains.

(3) Abnormalities in the Eye Surface Structure or Function

Tears are meant to cover the eye surface, providing oxygen and nutrients to the corneal epithelium. When tear function is low, dryness can increase corneal irritation, leading to an increase in tear production.

What to Do If Your Pet Has Severe Tear Stains?

As for the claim that tear stains are caused by too much salt in the diet, there is currently no published research or clinical reports to prove a link between diet and tear stains.

If your furry friend develops severe tear stains, it's best to consult a veterinarian for help. Treatments will vary depending on the underlying cause.
