Update

The vet called yesterday afternoon with the results of Loki's biopsy. It seems he had a form of Lymphoma that was apparently very aggressive. If left untreated a dog can only live 4-6 weeks with this cancer. If given treatment the dog will not make it more than a couple of months. So it seems Loki got sick shortly after Christmas and died one month later. So not fair that it had to take my Loki.
