Have to say that my nursing training has caused me to always take the "do everything at any cost" approach. Of course this is not feasible for everyone. I always want to believe a vet could never turn down a family or animal in need. I was surprised to learn at any early age that this is not always the case. I know I would try to do everything possible to help any animal in need, had I the means. Not of course if this meant the furkid would be subjected to undue suffering or pain at my selfish need to keep her or him with me. It can, as we all know, be a hard, very painful decision.
