What happens during pet euthanasia, step by step

Pet euthanasia is usually two injections given by a veterinarian. The first is a sedative that puts your pet into a deep sleep over several minutes. The second is the euthanasia solution, which stops the heart, usually within a minute or two. The vet then listens for a heartbeat and tells you when your pet has died. It works the same way for dogs and cats, at home or in a clinic.

And no, a dog cannot wake up after euthanasia once the vet has confirmed death. The movements that sometimes follow are reflexes, and they are explained below.

Before the appointment

A few decisions are much easier to make ahead of time than in the room.

• Where. At your vet's clinic, or at home with a vet who makes house calls. In-home visits usually need to be booked ahead.
• Who will be there. Decide who wants to be present and whether children or other pets will be.
• Aftercare. Communal cremation, private cremation, aquamation or burial at home. See pet cremation costs and options and aquamation for pets.
• Payment and paperwork. Ask to pay and sign the consent form beforehand, so you can leave without stopping at the front desk.
• Timing. Ask for a quiet slot, often the last appointment of the day, and whether there is a private room or a side entrance.

Bring your pet's own blanket or bed. Ask the vet whether a favorite meal beforehand is fine. For prices and the questions to ask when you call, see how much it costs to put a dog down.

What happens, step by step

1. Consent. You sign a form, and the vet explains what they are about to do. This is the time to ask anything, including whether they will talk you through each step.
2. Sedation. The vet gives a sedative by injection. It can sting for a moment. Over the next several minutes your pet relaxes and then falls into a deep sleep. You can hold them and talk to them throughout. Most vets sedate first, but not all do as routine, so ask in advance.
3. A catheter, in some cases. The vet or a nurse may clip a small patch of fur on a leg and place a catheter in a vein. Some clinics do this in another room. If you would rather your pet stayed with you, say so.
4. The final injection. When you are ready, the vet gives the euthanasia solution, usually into a vein. Your pet loses consciousness within seconds. Breathing slows and stops, and then the heart stops.
5. Confirming death. The vet listens with a stethoscope and tells you when your pet has died.
6. Time afterwards. You can stay as long as you need. No one should hurry you.

The injections themselves take minutes. Most of the appointment is unhurried time before and after.

What the body may do afterwards

These things are normal. They are not signs of awareness or pain.

• The eyes stay open. The vet may close them gently, but they often do not stay closed.
• A last breath, or several. A deep breath or gasp can come after the heart has stopped. It is a reflex of the breathing muscles.
• Muscle twitches. Small tremors in the legs, face or body.
• Bladder and bowel release. The muscles relax. The vet will usually put a pad or towel underneath.

A vet who knows you would like a warning will tell you about each of these as it happens. Ask them to.

Can a dog wake up after euthanasia?

No. Once the vet has confirmed that the heart has stopped, a dog or cat cannot wake up.

The fear comes from the reflexes described above. A breath or a twitch a minute after you have been told your pet is gone looks like life. It is not. Nerves and muscles can fire for a short time after death with no brain activity behind them, and your pet does not feel them. A sedated pet with open eyes can also look awake when it is deeply unconscious.

If you are worried, ask the vet to listen again before you leave. It is a normal request, and they will not mind.

Does euthanasia hurt?

The sedative injection is a needle prick, and some pets flinch or cry out briefly. After the sedative has worked, your pet is not aware of the catheter or the final injection. The euthanasia solution causes loss of consciousness first, in the way an anesthetic for surgery does, and only then do the breathing and the heart stop.

Occasionally a pet seems agitated or makes a noise as the sedative takes effect. This is generally understood to be a reaction to the drug, not pain. No vet can promise that every case will be perfectly smooth. Sedating first is what makes it as calm as it can be.

Should you stay?

It is your choice, and there is no wrong one. Many owners stay and say afterwards that they are glad they did, and a familiar voice and hand can keep a pet calmer. If you cannot face it, the staff will be gentle with your pet. A middle way is to stay until the sedative has worked and your pet is asleep, then step out.

Other pets and children

Some owners let their other pets be present, or see and sniff the body afterwards, and feel that it helps them understand. The evidence is limited, so do what seems right for your animals. It is easier to arrange at home than in a clinic.

With children, use plain and true words: the vet is going to help her die, she will not feel it, and she will not come back. A common piece of advice is to avoid "put to sleep" with young children, because it can make sleep sound frightening. Let older children choose whether to be there, and tell them in advance what they will see.

In-home or in-clinic euthanasia

Home suits pets that are frightened of the car or the clinic, large dogs that are hard to move, and families who want privacy. The clinic is the practical choice when it has to happen today. The procedure is the same in both places.

Euthanasia at home always means a veterinarian coming to your house. It is only ever performed by a vet, and it is never something an owner should attempt.

What happens next

If you chose cremation or aquamation, the clinic or the in-home vet normally arranges collection, and with a private service the ashes come back to you later. Many clinics will make a paw print or keep a clipping of fur if you ask.

If you are burying your pet at home, check local rules first and ask your vet how to do it safely. The euthanasia solution stays in the body and can poison wildlife or other pets that dig it up.

Grief after a planned death is still grief, and it is often mixed with doubt about the timing. There is a guide to coping with the loss of a pet for the days that follow.

If your pet cannot wait for the appointment

Call your vet or an emergency clinic now, whatever date you have booked, if your pet:

• Is struggling to breathe.
• Has collapsed or cannot stand.
• Is in pain you cannot settle, such as crying, shaking or being unable to rest.
• Has a seizure that does not stop, or several close together.
• Is a cat that is straining to urinate with nothing coming out.

Emergency clinics can perform euthanasia at any hour. If your pet dies before you get there, here is what to do when a pet dies at home.

If you have not yet decided, when to say goodbye covers the decision, and the quality-of-life scales for senior dogs and senior cats give you something to score and bring to your vet.

This article is general educational information about what owners typically see, not veterinary advice. Vets and clinics differ in how they carry out euthanasia, so ask yours to explain their own process beforehand. Euthanasia must only be performed by a veterinarian, and the decision about whether and when it is right for your pet should be made with your vet.
