Answer 1

Could be normal skin discoloration or if she has allergies or had fleas or some type of skin irritation in the past the skin can be discolored from chronic irritation. Also nipples sometimes have purple/black spots on them that are nothing to worry about.

Are they new blotches, or have they always been there? If they're new they could be bug bites, my pup tends to get a few bug bites around her v***a, too.
