Allergies
Allergies can play a role in tearing and staining. Dyes or additives can cause inflammation of the tissues around the tear ducts that block the flow of tears. Bacterial infection of the tear ducts should be treated with antibiotics. If you suspect your dog has allergies, you should ask your veterinarian for a blood test.

Water
Water, which contains large amounts of minerals, can increase mustache and tears. You should only give your dog bottled, distilled, or filtered spring water. Using a water bottle will help keep your dog’s face dry and prevent stains.
Problems with the Eyes
Any problem with the eye can lead to tearing, which can lead to tearing stains. Trimming the hair around your dog’s eyes will help tear it up. Hair can cause eye irritation. Ingrown lashes can cause tears. Check your dog’s eyelashes for lashes. Lacrimal drainage is another cause of lacrimation.
Tears overflow due to blockage or obstruction of the normal drainage system of the eye. There are many reasons for this. Channels may be blocked or absent due to a congenital defect. After an eye infection, the canals may become narrowed or scarred. Some dogs have eyelids. To help with this condition, your veterinarian may shave your dog’s eyes.
Desitin and Hydrogen peroxide
You can use dried corn starch on your dog’s face every day to lighten the stains. Rub cornstarch on your dog’s face and wipe. Then use a fine-tooth comb to comb through the hair. Desitin can be used to prevent staining. Covers hair and replenishes moisture.
A dilute solution of hydrogen peroxide helps to stain the tears. You need to mix one part of hydrogen peroxide with 10 parts of distilled water. Avoid diets that contain beet pulp or added food colors that contribute to the appearance of facial hair. Sometimes feeding dogs natural food can help with tears stains.
Try Antibiotics
As a last resort of tear stain treatment, you can try antibiotics. Tetracycline is an antibiotic. It should be administered for 3-4 weeks. Puppies should not be given tetracycline until permanent teeth have erupted. If permanent teeth are given to puppies before cutting, it can stain the teeth yellow. People who show up to their dogs add low-dose tetracycline to their dog’s food or water to prevent stains.
