Kendall, when you put Seamus down, you liberated him in the gentlest, most loving way from a body that was broken down and no longer working. I haven't had a near death experience, but I've read about them, and almost invariably those who went through it report a feeling of peace and, if there was pain, blessed relief. Seamus wasn't going to get better - the end would have come soon whatever the case but it might have dragged out excruciatingly and caused him suffering and confusion. How wonderful to pass over to the other side surrounded by people who love you and are sending you off with a prayer and a blessing. You did a good thing for Seamus. I believe that animals can sense this. He still loves you - be sure of it.
