Just to catch everyone up on Rambo. I took him in for a second opinion today with a vet that had seen him in the past (we did not know where she had moved to, but I found her). She did a needle biopsy of the lymph nodes in his neck and sent it out for pathology. She sent out some more bloodwork as well. She will call me as soon as everything comes back.
He lost another 2.some pounds since the last visit. Of course there may be a difference in the scales as well.
