A quick and painless death is the overriding goal of euthanasia. Most veterinarians won’t euthanize healthy animals or pets with curable ailments. Most vets also don’t euthanize a pet without first giving it some type of pre-anesthetic sedative. The purpose of sedation is to help the animal relax, help the veterinarian insert the needle quickly and efficiently and allow the euthanasia process to proceed smoothly. Sedation also helps prevent last-minute struggling, which can be especially unpleasant for owners who opt to be present during the entire procedure.
