I just read your post. I went through it with my boy. He had pretty much the same issue as Phoebe although he did not lose his appetite. His fever shot up to 107 and he was shaking and salivating when I took him to the emergency room. We had taken him 9 times during the previous year for various illnesses and no cancer was detected. This last time they found a mass that was bleeding into his abdomen. We could not save him. I still have not recovered. MY remaining basset Daisy is still very depressed. I am soo sorry about your phoebe. I pray that your end result is different than mine and I wish I had a magic cure to offer. Bev.
