Godspeed, Riley
I understand how hard that decision was for you, but believe me, you have eased his pain, even though yours is great now. You mentioned that Riley was crazy for pigs ears and cookies - well, there is a big fawn boxer Jake at the bridge that will more than likely be happy to share his pigs ears, and the big brindle boy, Titus, who will share his cookies. They are all running and playing, free from pain. (((HUGS))).
