Had my old buddy laid to rest a few weeks back. We hunted together for 9 years before the arthritis and hips forced him out. He made it to 12 and a half before he finally let us know it was time. I called our vet and she and an assistant came out to the farm.
It was a gorgeous bluebird day and we just laid down in the shade in the front yard. I had a frozen rooster from last year I've been using for training my griff, and we played "fetch" for a little while, tossing the bird a few inches in front of him so he could "retrieve" it while laying down, tail wagging like crazy. I wanted him to taste and breathe the intoxicating pheasant scent one last time. Afterwards, he actually got up on his own and said goodbye to my daughters and wife before limping back to lay down with me. I'm not exaggerating when I say how happy he was, and I am certain he knew what was happening and in his own way was thanking us.
The first shot took around 5 minutes for him to quietly and peacefully fall asleep. He was actually snoring as I cradled his head in my arms and lap. The second shot was directly into his heart, and it was over in a few minutes after that. No wincing, no pain, and actually no reaction at all, just my best friend gracefully passing through to the other side.
The ladies brought out a large, plush, canvas mat, and we gently loaded him onto it. The three of us carried him to the pickup with utmost dignity and respect. We laid him down on the back seat of their truck, filled out a little paperwork, I petted him one last time, and they backed out and left. A couple days later we got his ashes in a sealed artisan wood urn, with intricate carvings, along with a couple paw prints in clay. It was a wonderful experience, and I couldn't think of a better send off for him.
