ANY ONE KNOW ABOUT DOGS EUTHONIZATION?

[Sara]

Euthanizing an animal with an injection is the most efficient and humane method. The mediation used is a highly concentrated opioid, the same type of medication used for sedation. The only pain they feel is the initial needle stick. They may vocalize or jerk but they're already unconscious; its a reflex action. There are 4 planes or levels of anesthesia: 1 is fully aware and in control of your actions (this is the plane you're in right now), 2 is when out but your system its fighting the medication so you may flail and/or vocalize, 3 is the surgical plane and 4 is dead. Stages can not be skipped. The goal is to move through them as fast as you can. Animals being euthanized go through the same planes and it can look painful if you don't know what you're looking at.
As far as the number of animals you mentioned goes, very few pounds, shelters or rescue groups simply don't have enough funding to save then all,
