Thanks everyone for you thoughts and prayers. The vet said she is not in any pain right now, jut uncomfortable due to the big belly, but will monitor from week to week. I have an appointment a week from Monday. I think I will have him put her on something then, just in case. He has her on Lasix for water loss and vitamins right now and some sedatives for when she appears to be ainxcious (I haven't had to use that yet). I'm having to put her meds into canned dog food and give it to her that way, but that's ok, she likes it.
She has lost so much weight in the last two weeks, I really don't think she will make it a month and that might be really stretching it. She has been eating good and still begs with no problem, but I am affraid to give her too much food because of how big her belly is and fear it is too uncomfortable.
She has been pooing small amounts and it looks like a black tar. When she thru up yesterday it was really dark greenish-black. Is that from the cancer?
