I don't see how a dog thinking it's out for a walk and not suspecting a thing dying instantly is horrible if it has to be euthanized. The powers that be do, though, but the horribly painful drugs they give animals seem to be Ok.
I don't understand that a bit.
Years ago, when the time came to say goodbye to your best buddy, your best human friend would take him for his last walk in the woods.
A most difficult task.
