That's a great summary of what to aim for. And as soon as that real decline begins, I'd add, to be honest in recognising it and to let a beloved dog go gently with the help of a caring vet before the dog is seriously distraught and suffering. I firmly believe it is far kinder to release an animal slightly before what might be their 'ultimate' time than to wait and risk putting them through serious pain and trauma. It means watching them carefully and honestly and the line may be different for different people, but when you are really looking at only days, thee's real kindness in letting them go gently without the risk of the crisis that can happen if left too late. :flwr:
at the end stage of any terminal disease, an important goal is to give the dog as high a quality of life as possible, and that when the end finally arrives, the decline happens quickly, and not as a long, slow process.
