What causes dark circles under the eyes of dogs and how to get rid of them?

There are many causes of dark circles, most of which are endocrine disorders, ear disease, eye disease, dental disease, tear duct obstruction, heavy-smelling food, etc.

If it is very serious, you can go to the hospital for lacrimal gland removal surgery, but it is risky.

If it is found after examination in the hospital that it is caused by endocrine disorders, you can choose some nutritional products, such as Xueliang oral liquid, etc. You can also use some professional tear stain cleaning liquid, but the effect is slow and requires long-term persistence.

Professional beauty institutions can also quickly bleach, but they should pay attention to choosing professional products that are non-toxic, odorless, and not harmful to the hair
