In our daily lives, those cute and cute dogs have become the favorites of countless families with their unique charm. However, as dogs grow up, many poop owners will find that their dogs have tear stains. So, why do dogs have tear stains? What factors are related to the appearance of tear stains?

Genetic factors are an important cause of tear stains in dogs. Some dog breeds with short nasal cavities, such as Teddy and Bichon Frize, are naturally more prone to tear stains due to their special physiological structures. This is because the structure of the nasolacrimal duct is relatively narrow, making it difficult for tears to drain out, resulting in the formation of tear stains.

Dietary problems are common causes of dog tear stains. . Dogs who consume too much salt or greasy food can irritate their eyes and produce excessive tears. Over time, these tears that are not cleaned up in time will form obvious tear stains in the corners of the eyes. Therefore, providing your dog with a healthy diet and choosing foods low in salt and oil is the key to reducing the occurrence of tear stains.

Ear infections are also an important factor in causing tear stains in dogs. When a dog's ears are infected by bacteria or fungi, the pain and itching will cause them to scratch their ears with their paws. This action sometimes irritates the eyes and causes them to secrete more tears. Over time, these tears can form tear stains. Therefore, paying attention to your dog’s ear health and promptly detecting and treating ear infections are also important measures to prevent tear stains.

Blocked nasolacrimal ducts are also one of the causes of tear stains in dogs. The nasolacrimal duct is the tube that connects the eyes to the nasal cavity. When it is blocked, tears cannot drain properly, and tear stains form at the corners of the eyes. This condition is more common in short-nosed dog breeds.

Eye disease is also a cause of tear stains in dogs. For example, eye diseases such as conjunctivitis and keratitis can cause uncomfortable symptoms such as eye pain, itching, and congestion in dogs. These symptoms will stimulate the eyes to secrete more tears, thus forming tear stains. Therefore, regular check-ups of your dog’s eye health and timely detection and treatment of eye diseases are also important measures to prevent tear stains.

In order to help our dogs get rid of the trouble of tear stains. , we can take some steps to prevent and reduce the occurrence of tear stains. First and foremost, regular cleaning of your dog’s eyes is key. Use a clean cotton ball dipped in warm water and gently wipe your dog's eyes from the inner corner to the outer corner, making sure they are clean. In addition, it is also important to trim the hair around the eyes regularly. Keeping the hair neat and tidy can reduce the possibility of hair irritating the eyes.

There are many causes of tear stains in dogs, including genetic factors, dietary problems, ear infections, blocked nasolacrimal ducts, and eye diseases. In order to reduce the occurrence of tear stains, we need to pay attention to the health of the dog, provide a healthy diet, clean the eyes regularly and trim the hair around the eyes.
