We currently have a dog with a terminal condition. We know the end is coming. For us, we are monitoring his "good days" and his "bad days". Right now, his good days are still significantly ahead of his bad days.

Also, we made a list of his three favorite things to do over his lifetime. When he is no longer able to do two of them, and his bad days outnumber his good days, we will help him to the Bridge.

His condition is dementia. It isn't really anything you can put your finger on and it is hard to evaluate when to let him go when he isn't in any real obvious pain. Those lists will give us a concrete way to measure his behavior and feelings in order to make the right decision for him.
