The red hair is formed by the oxidation of the dog’s tears in the air, and it is not harmful to the dog if it is not cut. If a Bichon Frise has tear marks and the hair is red, it may be caused by a foreign body entering the eye, fire, blocked tear ducts, or a salty diet. Some people feed their bears human leftovers and meat when they keep them. Human food contains a lot of salt, and bears that eat too much salt and too much meat can become irritated and cause tear stains. If this is the reason for the tear stains, then you should pay attention to a proper diet and feed a light ecological food.
