Many dog owners will find that their dogs have obvious brown fatigue marks, and in more severe cases may continuously tear up. Why are there severe tear stains? This is likely a question in the minds of dog owners. There are many reasons why dogs develop tear stains, including diet and health problems. From the perspective of tear stains, it is constantly reminding dog owners to timely improve their dogs' diet and to regularly take their dogs for check-ups at the pet store. What causes of tear stains in dogs do you know?

1. Why do dogs have tear stains

Tear stains in dogs are a common phenomenon. Tear stains are actually tears secreted from the tear glands at the corners of the eyes. When the tear stains are noticeably brown, it means a large amount of tear gland fluid is flowing out from the corners of the eyes.

Ear canal infection

Many dog owners may doubt what relationship there is between ear canal infection and the eyes. Actually, the dog's ear canal and eyes have a very close relationship. If the dog's ear canal is often infected causing itching and pain, it will keep scratching its ears with its paws. The ears and eyes are very close; when the ear canal is uncomfortable, it will stimulate the surrounding nerves, making the eye nerves more sensitive, resulting in frequent tearing, which over time forms tear stains.

2. Nasal discomfort can also cause increased tearing

If the dog's nose is uncomfortable, congested, blocked, or inflamed, it will also increase tearing.

3. Diet

Dog owners know dogs cannot eat foods with too much salt. High salt content can cause internal heat in dogs and is an important cause of obvious tear stains. In fact, high salt also affects dogs' kidney function.

2. How to improve and reduce tear stains

Increased tear stains can also negatively affect the area around the dog's eyes, and in severe cases cause dermatitis around the eyes. Because it is influenced by moisture, bacteria can easily grow and cause infection. How to reduce tear stains? Actually, improving diet is an important method to reduce tear stains. Do not feed dogs foods with excessive salt. If feeding dog food, owners should observe if the dog has tear stains within a week of eating the food. If tear stains appear, consider switching to another brand. Some dog foods lack nutrition and contain too much salt, causing tear stains. Regular cleaning of the dogs' ear canals and trimming eye hair are also methods to reduce tear stains.

Regarding the causes and improvements of tear stains, dog owners should now know how to use diet and care to eliminate tear stains from dogs.
