Hi Lisa!
I'm sorry to hear about your little dog, Prissy, and I'm sure you are overwhelmed right now. A lot of time, owners find out about the TCC because it tends to give the dogs a urinary tract infection. Once the infection is cleared up the symptoms go away for a while. So I hope Prissy will have some medication that will do that for you.
I can also tell you positively that Piroxicam has been a wonder drug for my dog, Annie. She was diagnosed 2 1/2 years ago and is still well. Although not everyone has as great a result, we've been very very lucky. In the beginning I was so distraught, I thought she's be gone in a few months that I spent all my time worrying and not enjoying our time together. It is my biggest regret that I did not savor every second with her instead.
I hope the Piroxicam works for you as well--good luck to you both and have as much good time with Prissy as you possibly can!
Annie's mom, Marty
