It could be Jade has a dental problem such as a tooth root abscess causing this lump . You need to take her into a vet right away. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.
