Hi Cindy--
I remember the first time I saw blood in Annie's urine; I was positive the end was near. There are so many things about this disease that can freak you out--and having that poor prognosis hanging over your head is very tough.
That's why I try to encourage everyone (myself included) to stay optimistic and try not to worry. Since Annie's been diagnosed, her symptoms have come and gone; some vanish some new ones come along. Recently she had an accident in the house and it was that brownish blood color. I had never seen it before and was definitely taken aback by it. But it only happened that one time.
I used to say that the day her appetite vanished, I'd know the end was at hand--but a couple of months ago, she had some stomach problem (totally unrelated to the TCC) and didn't eat for several days; we treated her for that and were good to go again.
The more I am worried about Annie, the happier I make my voice when I talk to her and when I'm rewarded by that wagging tail, I always feel so much better.
Good luck to you.
Marty
