What are tear stains?
Tear stains are reddish-brown marks caused mainly by porphyrins in tears oxidizing on fur; damp skin may invite yeast, deepening the color.
Why tear stains happen
Common Causes
Key causes
· Facial anatomy (short muzzles, shallow sockets, tight ducts).
· Hair irritation touching the eye.
· Blocked/inefficient tear drainage (epiphora).
· Allergies/irritants (dust, perfume, smoke).
· Yeast overgrowth on damp fur.
· Dental/oral pain or infection.
· Diet/water changes; hard water may contribute.
· Puppy teething and stress-related tearing.
· True ocular disease or infections.
Daily care routine
Care Routine
· Have a groomer trim hair around eyes regularly.
· Clean under eyes 1–2×/day with warm saline or vet-approved wipes.

· Use a fine comb and keep good airflow around the face.
