I talked to the vet and they want to keep Goliath overnight, and probably two nights. When they give him the initial dose of medicine it will break up the cancer cells very quickly. All of these dead cells get dumped into the blood stream and must be removed by the kidneys. Because of this he is pumping him up with liquids (I assume with an IV again) and wants to keep the liquids moving through him while his kidneys are handling the doulbe load of the dead cancer cells and the elevated calcium. The chemo treatments are $200 to $300 every three weeks.
