Think of it as a peaceful event
I can't think of anything any more humane than putting a suffering animal out of its misery.
It is such an important event - and a real heart breaker as well. I cannot stand to see an animal suffer. An injection/or gas is so very final, but it also stops the pain.
I would have a hard time putting a perfectly healthy animal down. That is where I could not participate. Since you will probably be dealing with the sick and old animals, it should be angel like and yet still difficult, but necessary.
You certainly can feel comfortable sharing the discomfort, if you have it, with us.
Here's to Aly, the Angel to escort some of our furriest friends to the Rainbow Bridge.
