On Euthanasia: What to Expect (2024)

Previously in this series on euthanasia, we’ve discussed making the decision and scheduling an appointment to euthanize your dog. Today I’d like to discuss the procedure itself. Knowing what to expect may make it easier for you to prepare yourself. I understand that this topic is very sensitive and may be upsetting to some people, but strongly feel that knowledge is power. It can be very comforting to have a solid understanding of what will happen and what your dog will feel during his or her final moments.

When your vet euthanizes your dog, they will inject an overdose of a powerful sedative directly into your dog’s vein. This drug will cause the nerves in your dog’s body to stop sending signals (including pain signals) and will slow your dog’s breathing and heart until they eventually stop. Many dogs take a final, deep breath as they pass away. Sometimes dogs will urinate or defecate when they are euthanized due to the total relaxation that happens. If this happens to your dog, it will do so when your dog is no longer aware of what is happening. Euthanasia does not hurt. Afterwards, your dog’s eyes may be open (although the vet can close them if you wish) and his tongue might hang out of his mouth. If your dog’s body is moved, he may appear to burp or sigh as air escapes the lungs.

In many cases, your veterinarian may choose to sedate your dog prior to euthanasia. You can ask your vet to do this if you think it will make the process easier for you or your dog. Sedatives can be given orally by mixing them with your dog’s favorite foods or can be administered via injection into your dog’s leg or back muscles. The sedatives given via injection are more powerful than oral sedatives and will provide more complete relaxation.

In Dobby’s case, we sought advice from his veterinary behaviorist on the best drugs to make the process as easy as possible. I wish that I could tell you that he went peacefully, but to be honest his euthanasia was very difficult. Most dogs who are old or sick pass on quite quietly, but in cases like Dobby where there is a behavioral component to the euthanasia, it is not uncommon for them to overcome all of the sedatives in their system.

Dobby was given a double dose of his anxiety medication, trazodone, the night before his appointment. Three hours before his appointment, he was given another very large dose of this drug – four times the amount he would usually take. In most cases, this would have made him too sleepy to walk, but Dobby was still walking around and carrying his ball when the vet arrived, even though he was quite sleepy. He growled and barked at the vet and was on high alert.

When he was given another sedative via injection into his leg (because he was responding too aggressively for the vet to have a clear shot at his vein), Dobby started to show a lot of seizure activity in the form of head swinging. He also became very sensitive to noises and startled every time I sniffled (not an uncommon side effect of his seizures). At that point he was no longer aware of what was going on around him, so the vet gently injected the euthanasia solution into his vein. I held him close and whispered how much I loved him, telling him he was a good dog and that he didn’t ever have to be scared again, until I felt his body relax. The vet listened to his heart with a stethoscope and confirmed that he was gone.

If you’re preparing to euthanize your dog, remember that you have options. Dobby’s response to the process was extreme, and most dogs do not respond that way. You can choose whether you’d like to be present during the actual euthanasia or not. I personally wanted to be there for Dobby because I knew that my presence would help him feel less afraid. However, if you do not feel like you can be there for your dog that is also okay. Consider talking to your vet about sedation and staying with your pet until he or she is sedated, then leaving the area during the euthanasia itself. You could also ask a friend or family member that your dog knows and likes to take your dog to their final appointment or to stay with your dog while you leave the room.

Again, this is a very personal topic, and everyone deals with death differently. Together, you and your vet can help to make your dog’s final moments as peaceful as possible. Remember that euthanasia does not hurt. In assisting with many euthanasias over my career, I’ve noticed that after a dog is gone there is often a beautiful expression of peace that settles over their face. The pain or stress they’ve been experiencing no longer hangs over them, and it’s those of us who are left behind who have to deal with grief.

If you’ve made this difficult decision, how did your dog’s final moments go? Did you or your vet choose to sedate your dog ahead of time? Please feel free to share your experiences below. I really appreciate the kind and supportive community of dog lovers that follow this blog. There’s a lot of healing going on in the comments after each of these posts, and it’s a wonderful salute to the dogs who’ve brought us here that so many of you have felt willing to share.
