The history of companion animal euthanasia includes a blend of good and bad methodology, the shifting landscape of the human-animal bond, and maturation of the veterinary euthanasia experience. Time has shown us that critical exploration of what once was acceptable will lead the way to modern best practices. Animal welfare remains at the heart of the procedure, with equally matched attention now given to client and veterinary team well-being. Although euthanasia will continue to evolve, it is clear through the twenty-first century advancements, a tipping point of necessary change is upon us.
