Tear staining is usually caused by the overproduction of tears (epiphora). Stains appear as reddish-brown streaks under a dog’s (or cat’s) eyes.
Certain breeds like Maltese, Lhasa Apso Shih Tzu’s are more prone to tear staining and it’s much more recognizable in dogs with light color coats. While it may simply be caused by epiphora, it is important to speak with your vet to rule out any medical issue.
Medical issues causing tear staining:
|In grown eyelashes
|Abnormally large tear glands
|Smaller than normal tear duct openings
|Glaucoma or other eye disease
|Inverted eye lid
|Plastic food and water bowls / unfiltered water
Some dogs don’t pass iron-type molecules through their waste. Instead, these iron-containing molecules (called porphyrins) are excreted through saliva, urine and their tears. These stains have a rust-color appearance. If they turn more of a brownish color, your pet may have a yeast infection. This is usually accompanied by an odor, so your pet will probably smell.
How to treat stains:
Keep your pet’s face clean by wiping down his face at least 2x’s/day with a clean, damp cloth. Keep his face hair trim and schedule regular appointments with a groomer.
Colloidal silver applied to the eye area with a cotton swab great. It helps reduce yeast infections.
