What to use to put a dog to sleep: why only a vet can
Nothing at home puts a dog to sleep humanely. Only a vet can. Here is why, and the same-day, at-home and low-cost options you can call today.
General information, not veterinary advice. It can't diagnose or treat your pet. If your pet is unwell or you're worried, call your vet; in an emergency, go to an emergency clinic now. Full disclaimer
There is nothing you can use at home to put a dog to sleep safely or humanely. The only humane way is an injection given by a veterinarian, using a drug that only veterinarians can obtain. Human sleeping pills, allergy medicines, painkillers and "natural" remedies do not give a dog a peaceful death. They cause fear, vomiting, seizures and suffering that can go on for hours or days, and many dogs survive them in a worse state than before.
If you are searching for this, you are probably watching a dog you love struggle, and you may be short of money, sleep or both. There are real options, some of them tonight and some of them free or low-cost.
What can I use to put my dog to sleep at home?
Nothing in your house will do it. The medicine a veterinarian uses works like an anesthetic for surgery. The dog is unconscious within seconds, and only then does the heart stop. Nothing sold in a pharmacy, a grocery store or a health shop works that way.
Why home remedies and human medicines do not work
Owners most often ask about what is already in the bathroom cabinet. None of it is an answer.
| What people try | What tends to happen to the dog |
|---|---|
| Human sleeping pills and night-time sleep aids | Vomiting, wobbling and drooling. Some dogs become agitated and frantic instead of sleepy. Tremors and seizures are possible |
| Antihistamines such as Benadryl (diphenhydramine) | A racing heart, panting, agitation, tremors and seizures. Not a calm sleep |
| Acetaminophen products such as Tylenol and Tylenol PM | Liver damage and harm to the red blood cells, with vomiting, weakness and labored breathing, over a day or more |
| Ibuprofen, naproxen and aspirin | Stomach ulcers, vomiting blood and kidney failure, developing over days |
| Leftover prescription painkillers or sedatives | Unpredictable. Vomiting, panic, struggling to breathe, or a dog who wakes up hours later with organ damage |
| Herbs, oils, alcohol and other "natural" remedies | Vomiting and distress. None of them ends a life gently |
The pattern is the same every time. The dog is awake and frightened while the damage happens, the result is slow and uncertain, and you are left alone with a suffering animal in the middle of the night. Many of these products also contain added ingredients, such as decongestants or the sweetener xylitol, that are dangerous to dogs in their own right.
If your dog has already been given a human medicine, call your vet, an emergency clinic or an animal poison control line now and tell them exactly what it was.
How to euthanize a dog naturally: is there a way?
No. There is no natural substance that puts a dog to sleep peacefully, and withholding food or water is not humane either.
Letting an illness run its course is sometimes called a natural death. It is rarely the quiet passing owners hope for. It often takes days and can involve pain, nausea and a struggle to breathe, as signs a dog is dying of old age explains. The gentle version of a natural death is hospice care planned with a vet, with prescribed pain relief and an agreed point at which you will ask for help.
Can you put down a dog yourself?
You should not, and depending on where you live it may be against the law. Euthanasia is only ever performed by a veterinarian. Owners must never attempt it themselves, by any method.
Laws differ by state and country, but causing an animal unnecessary suffering is a crime in most places. A do-it-yourself attempt that goes wrong, as they often do, can be prosecuted as animal cruelty. It also leaves you with a last memory of your dog that no one should have to carry.
The humane way to put down a dog
A veterinary euthanasia is usually quiet, and the injections take only a few minutes. In most cases the vet gives a sedative injection, and your dog falls into a deep sleep while you hold them. The vet then gives the final injection, and the breathing and heart stop shortly after. You can usually be there the whole time. What happens during pet euthanasia goes through the appointment step by step, so you know what you will see.
How to put your dog to sleep today: the real options
Start with a phone call. Say that your dog is suffering and that you need euthanasia today. If money is the problem, say that too, in the first minute of the call.
Your own vet
Many clinics will fit in a euthanasia the same day for a dog who is suffering. If it is after hours, the recorded message usually gives the number of the emergency clinic that covers for them.
An emergency clinic
Emergency and 24-hour veterinary clinics are open nights, weekends and holidays, and euthanasia is something they do every shift. They cost more than a daytime appointment. Call ahead, tell them what you can afford, and ask for the total before you set out.
A vet who comes to your home
Many areas have veterinarians who carry out euthanasia in the home, and some offer same-day or evening visits. It costs more than a clinic because of the travel time. It suits a large dog who cannot be lifted, or a dog who is terrified of the car.
Free and low-cost euthanasia
If cost is why you are looking for another way, these are the places to call:
- Humane societies and animal shelters. Many offer euthanasia to the public for a reduced fee, and some waive it for owners in hardship.
- Nonprofit and low-cost veterinary clinics. Some are open to everyone and some are income-based.
- Veterinary schools. Some teaching hospitals have community clinics or assistance funds.
- Local pet-assistance charities. Some help with end-of-life costs. A shelter or your vet's front desk often knows who does.
Say it plainly: "My dog is suffering and I cannot afford this. Do you have a reduced fee or a payment plan, or do you know who does?" Clinics hear this often. How much it costs to put a dog down has typical price ranges and the questions to ask.
If your dog cannot travel
A frail, painful or very large dog can make the trip feel impossible. Tell the clinic. Depending on the dog and the vet, they may be able to:
- Send a vet to the house, or point you to a home-visit service
- Prescribe pain relief or a sedative for you to give before the journey, if the vet knows your dog
- Come out to the car, so your dog never has to be carried inside
- Tell you how to move your dog safely, for example on a blanket carried by two people
Only give what the vet prescribes for this dog, in the amount they tell you. The right medicine and amount depend on your dog's weight, age, kidneys, liver and other medicines, and only the vet can set them.
Getting through tonight
If the earliest appointment is some hours away and the clinic has told you it is safe to wait, keep things simple:
- A thick, soft bed in a quiet, dim room, with you close by
- A light blanket if your dog feels cool
- Water within reach. Do not force food or water into the mouth
- Absorbent pads or towels underneath, changed when they are wet
- No human medicines of any kind
If your dog is restless at night and not near the end of life, that is a different problem with different answers. See why an old dog paces at night.
When to call the vet today
Do not wait for morning if your dog has any of these. Call an emergency clinic now. A vet can ease suffering quickly, and some of these problems can be treated.
- Struggling to breathe, or gums that are blue, gray or white
- Crying, shaking or panting in pain that does not ease
- Collapse, or being unable to stand
- Seizures that repeat or do not stop
- A swollen, tight belly with retching and nothing coming up
- Heavy bleeding, or repeated vomiting
- Your dog has swallowed any human medicine
If you are not sure it is time
Some old dogs who look as if they are dying have something a vet can treat or ease. If you have doubts, ask for an exam before you ask for euthanasia. A quality-of-life scale for senior dogs helps you put what you are seeing into words, and when to say goodbye covers the decision itself.
Asking for help with the cost is nothing to be ashamed of. For afterwards, there is a guide to coping with the loss of a pet.
This article is general educational information, not veterinary or legal advice. Euthanasia must only be carried out by a veterinarian, and no medicine, supplement or home remedy should be given to a dog to end its life or to sedate it unless a vet has prescribed it for that dog. Laws on animal euthanasia and cruelty vary by location. Decisions about your dog's comfort and the timing of euthanasia should be made with your veterinarian.
