Pet's info: Dog | Chihuahua | Female | unspayed | 5 years and 8 months old | 9 lbs
While petting my dog’s belly, I noticed black spots on her nipples and much more of the same spots around her vagina. She licks her private area often, and has also developed slight aggression to that area being touched. The spots are black and oily, cannot be removed by just wiping, but can be individually pulled out (like hair follicles) by tweezers. There doesn’t seem to be any other affected area - her ears are clean. What is this? Can it be treated at home? Please help.
