Sorry I have not updated this we have been swamped lately. It actually turned out to be a snake bite of all things. Took her into the vet and she took one look and knew what it was. We tested anyways because I wanted to be certain. The lump was located on a classic CL spot on her jaw/neck line. The vet gave her some type of shot I dont remember now, but the swelling was gone in few days and she was jumping around acting normal.
