Hi Bellasmom! I hope you’re still around on the forum. This thread may end up being a godsend for my Rosie (5 years old, female). She has been dealing with the exact same symptoms as Bella for the last month. We’ve paid for x-rays, an ultrasound, a CT scan, an echocardiogram, blood work, and fluid testing, as well as 3 thoracentesis chest drainings (about every 10-14 days). There are no masses or signs of cancer or any heart issues. Her blood work is beautiful. The vets seem to be at a loss and are not hopeful. As our next option, they want to do a biopsy to test for mesothelioma and at the same time install a pleural port. I want to do everything I can to help my sweet Rosie as she is only 5! Can you update me on Bella on how she is doing now 2+ years later? And any advice you have that I can present to the vet would be so helpful! It looks like maybe we should think about installing 2 ports instead of 1 and then start Rosie on prednisone after the biopsy. I’m going to call the vet tomoknow what I’ve found on this thread!
