My dog has a black, moldy substance growing around her top K9 tooth. She has short, course hair and is always biting herself.

Black discoloration could indicate an infection or a foreign object trapped at the gum line. If you cannot easily remove it (be gentle), I recommend to have Jasmine examined by the veterinarian. Small dogs are more prone to dental disease and it is best to be proactive. Here is a link about oral health and care for pets:

I hope this helps and please feel free to post any additional questions.
