[usr] My dog has cancer. [sys] I am sorry to hear that.  Unfortunately a lot of dog breeds have a high risk of cancer.  Is it treatable? [usr] I guess not because the surgery didn't work so we have to put her down. [qst] [None] [bhv] [None]
Oh my.  I have been in that situation before.  You have my sympathies.
