Can Dogs Have Birthmarks?

Yes, it is possible for dogs to have birthmarks. These marks, which are also medically referred to as congenital melanocytic nevi, are typically dark-colored pigmented areas on the skin and are present from birth. In most cases, birthmarks in dogs are benign and considered to be a normal variation with no health implications. If a dog has a large or rapidly changing birthmark, however, it is advisable to consult a veterinarian to ensure that it is not a sign of a more serious condition.
