Dogs and cats have been observed to produce, at times, a reddish-brown coloured stain below the medial canthus of the eyes, around the mouth and occasionally on the feet and other less pleasant (for ophthalmologists) locations. Cats sometimes produce a much darker ocular discharge and, on occasion, a black plaque-like corneal sequestrum. 

This unpleasant staining around the eye is always the result of abnormal overflow of tears.

STAIN REMOVAL TIPS
  • YELLOW (URINE) STAINS OR OTHER STAINS ON FEET - mix 50% liquid Woolite and 50% human hair peroxide (20 volume), then dilute this mixture with 50% water. Add a small amount of a conditioning type shampoo. Shampoo this mixture into the stained areas of the coat and feet. Allow it to remain on for 5 minutes. Rinse it out and shampoo & condition as normal.
  • BORIC ACID POWDER - rub it into the staining with fingers and leave it there. Do NOT brush it out, it is left in the coat. Do this every day, also use a very fine comb to comb out any debris in the corners of the eye. Also, if there are any hairs in the very corners of the eyes, carefully remove these.
  • BORIC ACID SOLUTION #1 - make a paste of the boric acid powder & green lemon juice. Using a toothbrush, brush the paste on the stains and leave overnight. The next day, comb out and no more stains. For really bad stains, repeat again.
  • BORIC ACID SOLUTION #2 - use 1 teaspoon of boric acid to 1 cup of boiling water, let cool, use 1-2X a day, make a fresh solution every 3rd day, moisten cotton ball and wipe the eye and tear stain area
  • VETROPOLYCIN Sterile Ophthalmic Ointment - ¼ inch strip in both eyes once a day and wash area with warm water twice daily - for 10 days
  • CROWN ROYALE MAGIC TOUCH & PEROXIDE
    Mix Magic Touch grooming spray concentrate 1 part to 1 part water. Now mix this with 2% hydrogen peroxide - NOT the kind you use on your hair. You can mix up enough for a whole week and store it in a closed bottle. Apply with a cotton to clean the eyes.
  • CROWN ROYALE "WHITENER" - mix with human hair peroxide (20 volume to 40 volume) into a paste and leave it on overnight. You must condition very well. DO NOT get any mixture into the eyes. Crown Royale Ph: 1-800-992-5400.
  • MILK OF MAGNESIA, CORN STARCH AND PEROXIDE - use equal volume of MOM (plain white) and peroxide (20 volume to 40 volume), and then use the corn starch to make a good paste of this; put on and work well into the stained area and let dry 4 hours. Wash out, CONDITION WELL. Keep doing this for several days until tear staining is gone. Apply a thin coat of Destin diaper rash ointment after the area is washed out and dry. Try this every other day if possible and the choice way of doing it. If your dog has heavy stains then do this for 3 days in a row, then skip every other day.
  • CORN FLOUR, WATER AND A DROP OF BLEACH - 2 teaspoons of corn flour, add a few drops of boiling hot water and mix to a paste. Add 1 single drop of plain bleach, mix again. Allow the mixture to cool down and apply to the tear stain area. Allow to dry (10 minutes), wait 1 hour and remove with warm water and clean cloth. Then wipe on a thin layer or peroxide and allow to air dry and leave alone. Repeat every other day for 2 weeks. DO NOT get any in the dogs eye.
  • BAKING SODA - a mixture of ½ lemon juice and ½ baking soda works wonders when it comes to whitening coats. Make a paste and work into hair. Let the paste set for 5-10 minutes and wash and rinse thoroughly. Lemon juice can irritate your animal's skin, so be sure to rinse well. Condition well!.
  • PEROXIDE, MILK OF MAGNESIA & CORNFLOUR
    1 x bottle of Hydrogen Peroxide 40%
    1 x bottle of Milk of Magnesia
    Mix together into a paste with corn flour.
    Paint on and let dry and then either brush or wash out when its been on for a few hours
