This will depend upon the size, breed and health status of the dog as well as the geographic location you are in. Larger dogs require more euthanasia solution, and dogs that are frantic with pain or panic require sedation for the euthanasia solution to be administered properly.
Euthanasia (from Greek for 'good death') tries to give a humane death. But I believe that unless a cat is ill or suffering, with no hope, cats and dogs should have the same right to live and not be killed.
stray dogs and cats :( if you mean method, then they usually use lethal injections
It depends on the laws of the state. A degree in veterinary medicine is normally required to medically treat animals. ( Such as a Vet Tech) A euthanasia certificate is required for the sole purpose of performing the act of euthanasia. One example is a person who works at a shelter and it is their job to perform euthanasia on the sick injured or unwanted pets.
