The knackerman who deal with the last pony was so good at his job, it made what was a truly traumatic experience so much more bearable. I had walked around with Tim (the pony in question) after the vet had been and made him as comfortable as possible, and he had been leaning on me (he was in his twenties and I'd known him since he was a 3 month or so old foal).
When the time came to say goodbye, he was dealt with appropriately and passed away seemingly painlessly (the vet gave a lethal injection after a heavy sedative which saw him fall onto the floor pretty quickly). The knackerman left us time to say goodbye, and ensured that Tim's body was removed quickly and neatly, without us needing to see it happen. Moving an animal that weighs over a ton is clearly not easy, and it was done professionally and quickly. It was a relief to see him dealt with in a respectful manner, and was already a pretty horrible day was made much better by his professional manner and quick service.
I think jobs like these are so easily forgotten by people who don't have to deal with this sort of thing on a day-to-day (or even year-to-year) basis.
