Poor Princess. I'm not sure how old she is, but this black thing in her mouth could be something serious like cancer, and if it is getting bigger, that would make it hard for her to eat, which is causing her to lose weight. This is a medical emergency, and she has to see a vet now. You need to take her into an ER vet immediately.
