Does euthanasia hurt?

The short answer is no; however, the injection of a sedative prior to the euthanasia procedure is sometimes associated with a small amount of discomfort, like a quick burn or a sting. After that initial injection, your pet will become very sleepy and will feel no pain associated with the injection of the pentobarbital solution used for the euthanasia. All they will feel is that they are drifting off to sleep.
