I just returned from the veterinary clinic after two hours of tests on my dog. She fell sick yesterday and hasn't been eating. After a few tests they found that she had a build up of fluid in her abdomen. They suspect this is being caused by a tumour. Malignant or Benign? too early to tell. They will run an ultrasound tomorrow to find out for sure. If malignant they suspect she will have 2-3 weeks. If benign, well it depends on location, but it may be surgically removed safely. She had her abdomen tapped twice tonight and if the fluid builds she may start to bleed out. I'm at the beginning of what is sure to be a long night/weekend.
