What are the reasons for a dog's eye tearing?

A dog's eye tearing may be caused by injuries, foreign objects in the eye, internal heat, or eye infections. Owners should carefully examine the dog's eyes to see if there are wounds or foreign objects, and if so, help the dog deal with them in a timely manner. Additionally, if the dog also has symptoms such as increased eye discharge, red and swollen eyes, and difficulty opening the eyes, it is advised to consult a veterinarian and choose appropriate eye drops or ointments for treatment.

Eye injury or foreign objects

If a dog's eye is injured or has foreign objects such as hair, eyelashes, or dust enter it, it will stimulate the eye and cause constant tearing. Owners should carefully examine the dog's eyes. If there is an injury, there may be wounds, hemorrhaging, or swollen surroundings. In this case, owners should timely assist the dog in dealing with the injury. If there are foreign objects in the dog's eyes, they should be removed promptly. Rinsing the eyes with saline solution is recommended.

Internal heat

If a dog's regular diet is relatively dry or high in oil and salt, such as human food or animal internal organs, it can easily lead to internal heat and cause tearing and increased eye discharge. In this case, owners need to adjust the dog's diet, feed them less oil and salt-rich food, focus on light cuisine, encourage the dog to drink more water, and appropriately supplement fresh cooling fruits and vegetables.

Eye infections

If a dog has tearing in one eye along with redness, swelling, and difficulty opening the eye, it may be due to a bacterial infection causing eye inflammation, which is common in cases of conjunctivitis and keratitis. It is advised to consult a veterinarian and treat the dog with antibacterial and anti-inflammatory eye drops. There should be significant improvement within three days.
