Effective methods to eliminate dog tear stains:

1. Do not feed your dog food or dog food that is high in salt and contains a lot of additives and preservatives. It is best to choose a high-quality, low-salt, natural grain without additives or preservatives.

2. Give the dog more water. Water is also very important for removing tear stains. If the dog does not like to drink water, the owner can interact more with the dog and increase the amount of exercise. The dog will naturally become thirsty. Go and drink water.

3. The owner can help the dog do eye care regularly, which will help the nasolacrimal ducts to unblock and reduce the appearance of tear stains. It is best to do it once every morning and evening.

4. If it is a long-haired dog, it is best to trim the hair around the eyes regularly to avoid irritating the eyes and causing tears.

5. Ensure the cleanliness around the eyes. You can use a cotton ball dipped in warm water to clean the eyes, or you can also consider instilling some eye drops.

Reasons for dogs with tear stains:

1. Improper diet. Dogs take in too much salt or often eat stale food, which causes abnormal secretion.

2. Pets’ eyes are infected with conjunctivitis, keratitis and other diseases.

3. Bacterial infection of pet ears.

4. The lacrimal duct is infected and inflamed and cannot metabolize normally.

5. Some special breeds, such as Pug, Shih Tzu, and Japanese Dog. Dogs with such an appearance will have a large curvature of the nasolacrimal duct, so the amount of tears discharged is limited. Even the normal amount of secreted tears cannot be loaded, and ugly tear stains or even dark eye sockets will appear in the long run.
