I am sorry to hear you are worried about Bud. I am a veterinarian, and will do my best to help.
Do you happen to have the results of the biopsy? What exactly was biopsied, the enlarged nodes?
Biopsy reports don't just say "negative". It is usually a two page report of exactly what was seen. That report would be interesting to me, and might help. Since I can't see and examine him, the more information I have the better I can help.
That wil help. Since Bud is a Boxer, he is more prone to cancer than other breeds. The report may help me help you.
