Hello Angela,
I am fairly new to this message board as well. I just recently finished reading literally hundreds of messages on this website in what I believe to be in another section than under pets called canine bladder cancer. Here is the link.

If you cant reach it this way, then just google or search in your browser under canine bladder cancer and it should be one of the first few sites listed.
Anyway, first off, let me say how sorry I am to hear of your troubles. I too am going through a similar ordeal. My 16 1/2 year old dog Porky started to have blood in his urine over a month ago. At the time it was only occasional but I took him in to see the doctor and he was treated for what was assumed to be an infection. After five different antibiotics, xrays and several urine and blood tests, there was still no answer for the blood. As time went on the blood and blood clots became more frequent and after searching on the internet I found the information on this web site as well as a few others that indicated Porky was most likely suffering from bladder cancer. I went back to the vet when Porky had blood in his urine for two days straight and he was also leaking a little. Fortunately his regular vet was out and the substitute vet there usually works with an oncology vet. When I went over the situation with her and told her about what I read online about bladder cancer, she was in complete agreeement with me and that it was almost certain that it was bladder cancer. We put Porky on Pirioxicam, a form of pepcid to coat his tummy from the Pirioxicam and an antibiotic to help with any infection that may arise. It has only been a few days since we started this but Porky it still in good spirits, eats and drinks well. I dont think he is in any kind of pain or discomfort. As soon I see it, then I will know it is time to say goodbye.But as long as he is eating, drinking and has the occassional smile on his face, I am going to love him and spoil him. I encourage you to read some of the posts from the canine bladder cancer board. It will really help to understand what is going on and what different options there are. There are a lot of people who have gone through or are still going through this horrible situation and they all have ideas and methods that they have used (many quite successfull, many not unforturnately).
Unfortunately, this is not a battle that can be won, but there are things that can be done to make the time left better for you and for your dog.
I hope this message gets to you in time and that you can have some comfort in knowing that you are not alone.
