I just got back from the vet for Benji's lymph node check. Both neck lymph nodes are still a bit enlarged. All other lymph nodes are not palpable. The vet suggested to come back again in two weeks and if they are still enlarged he will do a biopsy. He doesn't think it is lymphoma but with our first Beagle's (Erin) struggle with lymphoma he understands my concern. January 6 is Benji's next check. I'll be on pins and needles until then. Thank you all for your good thoughts.
