Prevention and Treatment of Excessive Tears of Dogs
Some dogs have a lot of tears, and slowly they will have ugly tear marks, such as Teddy, Papillon, Pekingese, Chihuahua and other breeds.
Factors that cause abnormal secretion of lacrimal glands in dogs and increase tears: Acute conjunctivitis and keratitis caused by bacteria, viruses, etc. make the eyes unable to open and tears in the wind. Physical stimuli such as inverted eyelids and ectroped eyelids cause excessive secretion of tears in dogs. Due to ear itching and other external ear inflammation, dogs use their front paws to scratch and affect the trigeminal nerve, prompting the dog’s lacrimal gland to secrete more tears. Causes of abnormal drainage of the dog’s nasolacrimal duct: Physiological nasolacrimal duct structure is abnormal, such as some dogs with short nose, the nasolacrimal duct is more curved, which makes the excretion of tears not smooth, so there are many tears. Lacrimal punctum is backlogged, which is more common in dogs with more serious eyeballs. This causes the punctum to be backlogged and tears flow down the corners of the eyes. The nasolacrimal duct is blocked, and after a vicious circle, tears flow from the corners of the eyes.
Prevention method: Treat with some ophthalmic drugs such as anti-inflammatory eye drops; If eyelid problems can be corrected with surgery, they need to be treated as soon as possible to completely cure them; If it is caused by otitis externa and other ear diseases, it is necessary to clean the ear canal. If it is already inflamed, it needs to be anti-inflammatory under the professional guidance of a veterinarian; Dogs with abnormal nasolacrimal duct drainage need to take some drugs for clearing the nasolacrimal duct in order to drain tears normally and stay away from the trouble of tear marks.
