I agree and 9 times out of 10 its the most humane method, the dog has no time to get stressed or agitated BUT earlier this year I had to have my old boy PTS, and i couldn't do it with a gun, i chickened out, i called the vet to the house, they had to give him a muscle relaxant first as he was a little agitated, but after that he passed away fairly peacefully eating big chunks or cheese, i sat with him on the floor afterwards, just me and him and i buried him in the garden and shed a tear im not afraid to say............
