No way did you let Patton down. You did the right thing. It's always the toughest of all jobs putting a beloved animal to sleep, whether they've been w/us for years or for minutes. You did everything you could to make him comfortable and pain free and your vet wanted to spare him further pain and suffering. You were with him when he passed to his next life at the Rainbow Bridge. You made his transition easier. And you gave him the best gift of all, your love and compassion, the human touch while he was still w/you. Rest assured that no one here at PT is going to judge you. Far from it; they and I will tell you that your heart is full of love and it's hurting right now because your sweet Patton is gone. He came to you for a reason, my dear, and you fulfilled your purpose where he was concerned. I, for one, will say that it was for the best and Patton is now pain free, enjoying a much deserved rest. After that, he's going to play w/all the others who have gone before him. And he'll be waiting for your reunion and will greet you w/the love that you showed him on this earth.
