Reasons for dog lips turning pink

Under normal circumstances, dog lips should be black. If there is a simple discoloration without obvious hair loss or redness around the mouth, it may be due to body pigment. If there is a change, there is no need to worry about this; but if there is hair loss or redness, it may be a skin disease. Skin disease will directly cause the dog’s skin to discolor and lose hair, so you need to take the dog with you. The dog went to the hospital for diagnosis.
