The only person who can truly comment is the person who has walked in your shoes, felt your pain, and done the best that they could do against such unusually high odds: Anyone who has mirrored that experience wouldn't second guess you, they would honour you and support you. This is not a road that anyone walks easily, it's the hardest work, the hardest climb, the hardest wishing and hoping and then it is the acceptance and the deep abiding sea of love that carries you to the last breath. We all rage against the dying of the light, but with our dogs, the light never really leaves, it glows within us, it sustains us. Within our hearts and minds, they are forever healthy, forever young and forever loved and forever at our sides. Never fear, when you open your eyes on the other side, Jake will be there and he will thank you for keeping him from further pain and suffering. He knows how much you love him...he's not afraid because you are with him.
