I hope you dont find this intrusive, but I read your post from 3/2011 about a boy you lost due to cancer of the prostate, and I was hoping I could ask you some questions.
I'm a veterinarian practicing in New York, and I have recently seen 5 male Boxers in the same age range who developed an atypical tumor of the prostate. I have AKC records for 3 of them, and all 3 have 1 common ancestor.
If you are willing to share your story with me, please message me back. Thanks so much.
