Understanding Euthanasia

Difficult decisions, understanding pet loss and grief


Having to make the decision to end a pet's life is never easy. It is a subject that many people do not want to talk about until they have to, but then it becomes a decision made under emotional stress. The purpose of this article is to explore what happens when an animal is "put to sleep" and how to handle the grief from losing a pet.

Making the Decision
It is an intensely personal decision to euthanize a beloved pet due to injury or disease. People often wonder if they will know when it is "time." Many ask their veterinarian "what would you do if it were your pet?" As a veterinarian, I could never make this decision for any pet owner (just stated the medical issues and facts), but offered this thought: it is probably "time" when the bad days begin to outnumber the good ones. Pet owners usually have a idea of what is 'good' and 'bad' in the life of their pet.

What happens when an animal is euthanized
(NOTE: Each veterinarian has their own protocol. This is written from my personal experience) I prefer to give a sedative tranquilizer prior to the euthanasia drug, which is given in the vein. The tranquilizer is either given as a tablet by mouth or a painless injection under the skin, like a vaccination. The animal is then restful and the owner may elect to spend some quiet time saying goodbye. Each case is different -- if the animal already has an IV catheter or medical conditions dictate otherwise, I do not sedate.

At this point, the owner may say goodbye to their pet and leave the veterinarian to finish the task. Other owners choose to spend some quiet time now and stay for the whole event. There is no right or wrong way to handle this. As the pet's caretaker, this is entirely your choice and what you feel most comfortable with. If people are unsure as to what is 'right' for their situation, I tell them to consider the pet -- if the person is very emotionally upset, some pets become stressed upon seeing their human distraught.

The euthanasia drug itself is an overdose of a barbiturate that stops the heart and breathing muscles. This is administered through an IV catheter or with a needle and syringe.

Things to be aware of as death occurs:

  • the eyes don't close.
  • there may be a last gasping breath, called an agonal breath, that is more of a muscle spasm. The animal isn't aware of this.
  • there may be vocalization.
  • there may be muscle twitching.
  • the heart may continue beating for a short period after breathing has stopped.
  • the urinary bladder and possibly bowel contents will be released.
  • In most circumstances, you will notice nothing except a peaceful release of tension, as in 'going to sleep'. Due to each animal's individual health situation, things will be different animal to animal.
