The change in Bichon Frize skin color from pink to black may be caused by pigmentation, skin disease, sunburn and other reasons. First, check whether the dog has skin diseases. If there is a skin disease, it needs to be treated in time. If there is no skin disease, then there is no need to worry.

Tips:

It is best not to expose your dog to the sun, especially in summer. You cannot shave your dog bald, otherwise the dog’s skin will be damaged. It’s easy to get sunburned.
