Tear troughs can occur when dogs suffer from eye diseases, such as dacryoadenitis. If the lacrimal gland is congenitally narrow, the problem can only be solved by surgical dredging. When dogs are severely affected by ear mites, they may shed tears and cause tear stains. In this case, the ear mites will get better after being treated with ear mites.
When the hair around the dog's eyes is too long, it can easily irritate the eyes and cause tears, resulting in tear stains. At this time, you can improve the situation by regularly trimming the hair around the dog's eyes. You can also use warm water to wipe the area around the dog's eyes, or use eye cleaning products to help clean the dog's eyes and alleviate the phenomenon of tear stains.
