Having Your Dog Put To Sleep - What Actually Happens?

28 CommentsTuesday, 1 August 2017  |  D for Dog

One of the most difficult things we do as dog owners is to have our beloved dogs put to sleep, because they are suffering in some way, maybe through disability, ill health or old age. As harrowing as it is, I am always so very glad that we have the option of euthanasia, rather than letting them suffer.

Tat and Cleo

However, with the option of euthanasia comes responsibility. Are we doing the right thing? Is it too soon? Are they suffering or would they prefer to live? So many thoughts go through our minds. The option of euthanasia is a burden of responsibility as well as a blessing.

Quality of life is really what matters. This well written blog by Dr Rosie Smith gives a check list of the main aspects of quality of life, if you need any guidance. But do trust yourself to know when the time is right. You will know.

How will I know when it’s time to say goodbye?

Once you have decided that it is time, the process of euthanasia itself can be a bit of a mystery and fear of the unknown won’t help at an already harrowing time. It is not the kind of thing we feel we can discuss with others who have gone through it. Even the most peaceful euthanasia can be painful to recall. There is an injection and there is death - that is about as much as any of us know until we have experienced it.

Although this is an incredibly difficult thing for any of us to discuss, I can’t help feeling that many people would benefit from knowing beforehand exactly what to expect. The first euthanasia I experienced was definitely the worst and I think that is partly because I wasn’t sure what was going to happen. Knowledge helps us to cope. The unknown can be very scary, at a time when we are already feeling so many powerful emotions.

So here we will talk about exactly what happens and how much time the process takes, so at no stage do you have the added anxiety of not being sure what will happen next and how much time is left.

Firstly, let’s talk about going to the vet or staying at home for the euthanasia.

Home or away?

People will differ on their preferences and there is no right or wrong answer. Every dog is different and every person is different. Not all vets offer house calls so you may not even have the option of a home euthanasia. Don’t worry too much about this. Just do what you can do.

When our first dog, Boycie, was put to sleep, we had the vet come to our house. I imagined Boyce would feel more relaxed at home but in reality I think he felt worried by the strange man who suddenly appeared in the living room and rather rudely started to examine him while he was trying to sleep on my lap. For a long time afterwards I also felt incredibly sad looking at that place on the sofa, which had previously been a happy place of evening cuddles. Little things, but for us anyway, it was enough to make us decide that next time we would go to the vets – which we did.

Staying at home does dispense of that dreaded final outing and the panic of the vet visit, if you or your pet feel anxious there. It can also reduce the strain on a very sick animal, as you don’t have to transport them to the vets and put them through that stress.

But going to the vets can also have its advantages. It is a place where dogs are used to seeing a vet and being examined, so the process will be more expected for your dog. Some people may worry about doing such a sad thing in public but believe me, the receptionist or people in the waiting room will be the last thing on your mind. If you have a good vet, they will be just the right amount of sympathetic and practical and will give you plenty of time with your pet. Also, if you are letting them deal with your pet’s body afterwards, already being at the vets is not such a bad thing.

As I say, there is no right or wrong place and we will all have different reasons for either wanting our dog put to sleep at home or at the vets.

As most people will have euthanasia performed at the vets, I will talk in those terms but the actual process is the same either way.

The appointment

If this candle is lit, someone is saying goodbye

When you make the appointment, tell the receptionist that it is an appointment to have your pet put to sleep. They will give you a longer appointment time, will not ask inappropriate questions in the waiting room like “how is he today” and they will do their best to make sure the atmosphere is as respectful as possible.

I also ask if sedation is used - sometimes referred to as “two injection” euthanasia. It’s important and I will discuss this further in a moment.

If you are taking your dog home after the euthanasia, remember to take a blanket with you so you can carry them home with dignity.

At the beginning of the appointment, don’t be surprised if your vet still does all the usual things first like checking your dog over, listening to their heart and so on. If something has suddenly happened to your pet, the vet will need to make their own assessment before they agree or otherwise to the euthanasia request. Even if your pet is old or has an ongoing issue, the vet will still probably check your pet over one last time.

Once everyone agrees that euthanasia is the best course of action, your vet will start the process.

If you need to sit down, don’t be afraid to ask for a chair. But if you can, stay with your pet, at least for now, so they are comforted by your presence. People often worry that when the time comes they will go to pieces. What is more likely to happen is that you will find an inner strength. You will be strong and be there with them for this final journey. This is about making your pet’s last moments as calm and peaceful as possible, and you will be surprised that this is something you can do, for them. Talk calmly and gently to your pet, so they know all is well. If you can’t trust your voice, just be near and calm. You are doing the right thing. All is well.


Your vet will hopefully prepare an anaesthetic or sedative injection for your dog. This is generally subcutaneous, meaning that it just has to go below the skin or maybe into the muscle and doesn’t have to go directly into a vein. It can simply go into the rump or leg, so it not so stressful or painful. This is a much more pleasant way to slip into peace. Your dog will hardly know what happened and will simply start to feel pleasantly drowsy.

You will notice that I said “Your vet will hopefully prepare an anaesthetic or sedative injection for your dog”. Some do not. Having seen it done both ways, the “two injection” method is definitely my preference. Boycie was not sedated first and he panicked as the vet pulled him about, trying to get the injection into his vein. Once the injection did go in, he was dead within seconds. It was unnecessarily harrowing, undignified and way too sudden – not the peaceful and a gentle goodbye we had hoped for. The only time a sedative may not be necessary is if the pet is already slipping into unconsciousness naturally.

dog sedation

After the sedation has been given, gently hold your dog as they begin to drift off. Their legs may start to buckle and their head may hang down as they get very sleepy, so make sure you support them without restraining them. They may react a little bit to the feelings of loss of control and may even try to get off the table or struggle a bit. Just help them to feel as calm and comfortable as possible.

After a few minutes they will become incredibly drowsy and you may like to hold them in your arms. Your vet may leave the room while you have some final alone time. Generally you have about 10-15 minutes with your dog as they go into a deep sleep. It is a precious moment.

So far your dog has only been sedated. They are still alive but fast asleep and may even snore peacefully.  They may still have a level of awareness, so continue to be calm and gentle. Hysterics won’t help your pet. Be brave. I always feel comforted by their gentle breathing and peaceful body. I have a last kiss and cuddle, thank them for their wonderful companionship and say goodbye.

You have done the most important part for your pet now. If you feel you don’t wish to be present for the actual euthanasia then tell your vet how you are feeling.

The final injection

Once your dog is fast asleep your vet will check their responses and then prepare the final injection. This one is injected into a vein so there may be a bit of searching for the vein, especially in a very ill dog. Don’t worry about your pet feeling any pain now as they are very deeply asleep.

My understanding is that this final drug is commonly a high dose (overdose) of an anaesthetic drug. Once administered, your dog will become unconscious incredibly quickly. The brain will stop functioning after just a few seconds and, because the brain works the heart and lungs, within about 20-40 seconds your dog will stop breathing and their heart will stop beating. Sometimes people worry that euthanasia works by causing their pet to have a heart attack, but this is not the case, so do not worry.

The vet will listen to their heart and check for reflexes. After a minute or two they will confirm that your pet has now passed away. Your pet’s eyes will probably be open and they may soil (this may also happen at the sedation stage), as the body is now completely relaxed. This is all normal. Don’t be alarmed.

Sometimes the passing is as quiet as a final breath, or sometimes a pet may gasp, twitch, vocalise or even move. Don’t worry, this can happen and is not unusual or anything to worry about. They are not suffering. Having witnessed this myself and being a little alarmed, I was told that it is just reflexes and electrical impulses in the body. This can be a natural part of any death.

I read a wonderful article by Adrienne Farricelli, a former veterinary hospital assistant.

Understanding Dog Pain During Euthanasia

This quote says it better than I ever could:

"Acknowledging what happens and acknowledging things that may go wrong is helpful. That way if things go well, you'll likely think "Is that it? That was very quick and peaceful!" and if things don't go very well, at least you know what may likely have happened so those last moments won't haunt you day after day as you wonder if your pet suffered. Truth is, the death of our pets is never pleasant to witness, but it's far better than suffering day after day, and most of all, our dogs will be eternally thankful for this last gift of unconditional love."

After the vet has confirmed that your pet has passed away, they can help you wrap them in the blanket, if you wish to take them home. You may be doing a home burial or taking them home for any other pets to say goodbye to. I do feel this is important. Other dogs in the household will want to know where their companion has gone, so do this if you can.

If you are doing a home burial, you might like to read Burying Your Dog at Home.

Did I do the right thing?

Euthanasia saves our beloved pets from weeks and months of unnecessary suffering. You thought it all through and did your very best for you pet and yet you may still feel guilt or worry about having had your pet put to sleep. Was it too late? Was it too soon? The chances are, it was just right. You loved your pet and you did the best you could for them. Be kind to yourself, trust your decision, know you did it with love and let any guilt go. Your beloved dog would say “thank you for caring” and that is all that matters.

Thank you so for loving me. You know I love you too,
and that’s why it’s hard to say goodbye and end this life with you.

So hold me now just one more time and let me hear you say,
because you care so much for me, you’ll let me go today.

From “May I Go” by Susan A. Jackson

I hope this has helped anyone who needed comfort and knowledge at this sad and stressful time.

To all the doggies who have passed or are about to go on this last journey - Run Free!

Far to many people do not know about two injection euthanasia ,I know of several people who have had to listen to their pet cries as the vet looks for a vein,hopefully your very good article will help to inform them so they can tell the vet that they want the animal sedated before the final injection is given if the vet refuses, I know of some that do then as difficult as it is they have to take courage and ask for another vet

Thanks Anne and yes, I hope it helps people. The two-injection method is the main reason I wrote this. I had no idea when we had our first dog PTS. I was shocked at how much better (for want of a better word) subsequent ones were, simply because it was a different vet who did the two injection method. I really hope people have the courage to read this. It took a lot of courage to write, I don't mind saying. Personally, I would always ask for another vet if they refused to do two injections. I learnt from bitter experience.

I have put a few dogs to sleep and it has always been the one injection method as they were near the end of their lives. I recently had to put a young dog to sleep, I had rescued it, but it had so many problems that it was attacking dogs and people rather badly. I spoke to the local dog warden and was advised that the dog should never have been rehomed. I would have to keep her tied up and muzzled for the rest of her life (she had just turned two) or put her to sleep. I took her to the vets complete with muzzle and her sedated her first (after a struggle) then when she was very drowsy he gave her the final injection and she went very quickly.

Reading this very informative article has brought me to tears as it has brought back the memories of having our darling Lab x Retriever aged 15 & 1/2 years put to sleep during the summer. We had the vet come to the house as our boy hated going to the vets; she came and he seemed genuinely pleased to see her and he even got out of his bed to say hello. Once she persuaded my husband that having him (the dog!) PTS was the kindest thing we could do then she set about proceeding with the 2 injection method : sedative first followed by the blue cocktail - I assumed it was potassium to stop the heart. There was no way that our darling boy was giving her his leg for her to shave in order to access a vein, so she gave him an intra-muscular injection into his flank so as not to stress him out and left us to cuddle and kiss him whilst he went off into a deep sleep. After 15 or so minutes he gave a big sigh - and for me I felt that was when he had gone - she then shaved his leg and administered the blue liquid. She checked his heart, said heíd gone then he gave a big, judderey sigh and twitched a bit and that was it; our beloved boy was no more.

Up until this point I would say having him pts at home was the kindest thing we could do and I was pleased that our vet was so respectful of both him and us but once heíd gone - and because weíd decided to have him cremated so she was taking him back to her practice- she then started to stuff him in a big bag, squashed him down like one would a sweater into a carrier bag- and then we had to carry his now squashed but still warm body to her car. That was all so undignified which is where going to the vetsí is better because one doesnít see the grim ending of oneís beloved pet. When I went to the practice a few days later to sort out the paperwork for his cremation we talked about it and she said she needed to work on that part!

A friend told us a few months before our boy was pts of the horror they had experienced at their vets when their dog was pts and how badly t traumatized them and how traumatic and endiyit was for their dog. I can only assume their vet did not sedate by any means possible their dog. So I would advise anyone planning on having their dog pts to absolutely insist on sedation being given first.

I recently had my 14 year old border collie put to sleep. I found your site comforting. I did feel guilty and was it to soon but she had cancer and I put her to sleep because I loved her and wanted to spare her going through the pain before it started. I will always love her.

My Boston Terrier Nelly who was 3 months shy of 14 and a half yrs old became really ill and when I took her to the vet they told me that she had heart failure and liver failure and didn't know how long she had to live but that she didn't look like she needed to be euthanized and that I could start treatment but that it may not help. That day she was given a b12 shot and antibiotics and I was also giving her a stool softner to try to get her to poop. A few days later we picked up the medicine for her liver and started it after 11 days with no signs of improvement we decided to euthanize her. I had read up on it and assumed she would get to shots and it would be pain free but I was wrong. I already felt bad then they made my baby jump and scream and within a few seconds she was gone. I felt even worse knowing her last thought was probably wondering why her mommy and daddy was leting someone hurt her. Worst thing I ever did. Like I said I thought she was supposed to get a seditive first.

I'm so sorry for your loss. The same happened to my girl Jessie. It's been 5 years now but I will never forget it .the vet came to our home but only used the one injection. Jessie really struggled. I felt and still do that jessies last moments she was thinking we were hurting here . I did not know what to expect .I just wish the vet had given us the option to have 2 injections .best wishes from Julie

Thank you this article has really helped and put my mind at rest! Tomorrow I take my 18 year old terrier to be put to sleep! One of the hardest decisions of my life!! Will be requesting the 2 injection method! As this is definitely the least stressful for him! My heart is already broken!

I have a 15 year old chiwauwa mix. She is diabetic and blind. We are fighting to control the pressures in her eyes now she has developed glaucoma. We could have her eye removed but I'm struggling with putting her thru all of that. I love her dearly I've had her her whole life. I don't want to feel like I've gave up on her but I don't want to keep her here for my own selfishness.

I sadly put my staffy to sleep last Monday the 8th . I wish I had read this arrival before hand . My heart is broken and my house donít feel like home . She had dm and was suffering for over a year and the time was right the vet also agreed I let her go with some dignity . Nothing can prepare you for letting your fur baby run free . I for one wasnít prepared for the hurt I feel and the guilt Iím holding , was it the right time ect ?! The vet did carry out the 2 step injection but Iím sad to think I wasnít given time to hold her or gently cuddle her and kiss her before they gave her the final injection . They told me they was taking her out back to put the canula in the vein . When they returned with her in there arms she was already sedated 😞 this will haunt me forever . They then administered the final injection within a minute of bringing her back in . I did how ever cuddle her and kiss her whilst she slipped away . Missing my darling girl so much

We had our beloved Shih Tzu, Oreo, put to sleep on November 21, 2018. We knew the time was approaching, and when he started yelling in pain throughout the night, we took him to the vet in the morning. Oreo was 18. The vet and staff were wonderful to us and Oreo. Oreo had the two step process. They allowed me to hold and comfort Oreo the entire time, while my partner was comforting me. After he was sedated, we had time alone with him, where we hugged him, kissed him goodbye, and thanked him for being our ďchildĒ. Of course, we were crying, but we knew we could not be selfish. When the vet came back in, she asked if we were ready. We were. She administered the drug, and Oreo passed while resting in my lap. The vet then left to give us time to grieve with Oreo. When we were ready to go, we pushed a buzzer. The vet came in and gently took Oreo from me and promised to take care of Oreoís remains with the highest of dignity and honor. She then told us we could leave through a side door, so we would not have to go past the lobby or other pets. We received a card yesterday from her, expressing her condolences for our loss. Our veterinarian is truly the tops and gets its! She made a difficult day a little bit easier for us.

Had to put my pit bull down 2 months ago, he was 13 & never harmed anything. But it was a bad experience for me. First all they muzzled him, they didn't sedate him they just held him down while he struggled not knowing what was happening. Breaks my heart when I think about him looking at me like what are they doibg to me mama.

Condolences, and i have been in that horrible position several times. It never gets any easier.

We just put our 12 year old lab down. She had 2 injections. The sedative did not relax her the way we all thought it would. In our case her whole body started to shake. She kept looking left then right like she was seeing things! We spoke calmly to her trying to calm her. My husband has put 3 dogs downprior to this and never did he see this kind of reaction before in the other dogs. Vet came in and saw her so said she could have had a bad reaction because she was on Rymadel and Tramadal before she came in and maybe those drugs interacted with the sedative drug. I felt horrible at the time but felt it was good we were there to talk to her during this 10 15 minutes. The vet gave her more sedative then she quickly came around to her front paw and gave her the heart stopping drug. She was gone in 30 seconds. I felt bad she had this reaction to the sedative but just like people some react different to meds. Thats why its best to be with your pet so they can hear your voice and feel comfort in you being there with them.

Hi. My dog will be put to sleep in 8 days. He is no longer able to walk and it saddens me to see him suffer. His name is Lucas, keep him in your prayers please. Also, how do I cope with his death?

Just one day at a time sweetie. Know that you did the best thing for him and that you shared great love and great times. I was a mess when my Berkeley died and a friend said to me "Would Berks want to see you this upset" and the answer was of course no. That really helped me, so I am passing that on. It is important to cry and grieve but also to remember and smile. Take care x

Comforting site and lovely words. I feel more at peace now. We had our 13 year old beautiful Spaniel euthanized this week. She slept peacefully with the sedative but gasped a few times after the final injection. The vet did say it was just reflexes and she had passed within seconds of the injection. This has reassured me

We have a 15 year old parson Russel Terrier, she used to love going on long walks and would spend all day playing with her ball. Now she only wants to go for small walks, sleeps most of the day. But she has started to get really aggressive, yesterday I went to move her off my bed and she lunged at my face.... I needed 12 stitches. We have decided that we need to have her pts. Itís the right thing to do but why do I feel so bad and that I am betraying the little lady who has given us so many happy memories x

Big hugs to you Kim. Please don't beat yourself up. It is normal to feel that way when you love them. In my experience, no he didn't feel pain and no, he didn't know what was happening. All he would have felt is your love. You did what you did because you love him and you put him and his needs first so you 100% did the right thing for him and he would say thank you xxx

Hugs to everyone who lost their beloved companions. I had to put my Swiss Shepherd (Cody) to sleep today. The hardest experience ever, a part of me feels guilty. I tried everything but his health had deteriorated and he wasnít eating anymore unless forced. Seeing him take his last breathe is an image engraved on my mind forever. He loved me and I loved him dearly. I had to put him first then myself and my heart break. Forever in my Heart Cody💞
