Sad day. I took Vanessa to the vet to send her over the bridge. He and I discussed that we believed it was cancer when I took her in three weeks ago . . . didn't have a biopsy, etc., done because I felt the problem was serious enough that very little could be done, especially when a dog is 13-1/2, half blind with cataracts and diminished hearing. Today he confirmed what I thought the problem was: perianal adenocarcinoma, one of the most aggressive cancers. Overall she lost 11 pounds, poor thing. But now she's young again across the bridge, frapping with all the other dogs and puppies.
