Update! My Murphy eventually stopped throwing up and lost over 3 lbs. We did not do the barium study because the Vet said it was to rule out Mega-esophagus, which he suspected. There is no cure for it only management. We have changed the way we have been feeding him with great success. He was overweight before, and now at a normal weight and he looks good, although, its a short lived victory :(. Had Murphy at the Vet again a week and a half ago for an ear infection. Received medication. Took him back a week later because we felt a lump near his anus that we thought might be his anal glands needing to be expressed. The Vet examined him and said this was a tumor and the prognosis was poor. He measured it, by anal examination, to be 4cm. He recommended surgery to remove and biopsy immediately because this form of cancer is very aggressive and wanted us to give him more time. I went home that night to talk things over with my husband. At this point we are not able to afford almost $1,000 for this procedure to be done. We read that following the surgery, problems with incontinence and infection can arise as well as the tumor coming back. Also chemo and radiation are recommended after adding a lot of extra cost. We may get a few more months, maybe a year or 2. During this time he would have to undergo continued monitoring by x-ray, ultra-sound and blood work. I feel horrible that we are unable to do this, but not sure I want to put him through it all. He seems happy now with no side effects of the cancer other than the tumor. We are just going to take it one day at a time and enjoy him for whatever time he has left. I am hoping someone has gone through this who might be able tell us how things might progress and what to do as things arise.
