A brief discussion on Animal Euthanasia and its suitable methods

Animal Euthanasia


Euthanasia term is originated from the Greek word which means good death. Animal euthanasia or Pets euthanasia can be defined as is the action of placing an animal to death. Reasons for euthanasia can involve painful (and especially incurable) conditions or diseases. Lack of sources to continue supporting the different animals, or laboratory test methods. Euthanasia procedures are designed to cause less pain and distress. Euthanasia is separate from pest control and animal slaughter although in some conditions the procedure is the same.



The methods of pet killing can be divided into the physical and pharmacological method.  Suitable pharmacological procedures involve injected drugs and gases that primarily depress the central nervous system and then cardiovascular function. Suitable physical procedures must first cause quick loss of consciousness by depressing the Central Nervous system. The most common procedures are discussed here, but there are other suitable procedures used in different conditions.

Intravenous anaesthetic:

Upon injecting of intravenous anaesthetic, unconsciousness, cardiac then respiratory arrest follow quickly, usually within 30 seconds. Some veterinarian’s doctors take action of a two-stage process: primarily intravenous injection that simply reduces the pet consciousness and a second stage that causes death. This method permits the owner to say goodbye to a pet without their emotions stressing the pet.

For large pet animals, the level of barbiturates necessary is considered by someone to be unusable, although this is standard practice in the United States for a painless death. For cattle and horses, other drugs may be presented. Some specially designed combination products are also available, such as Somulose andTributame which cause severe unconsciousness and cardiac arrest with a lower level of injection, thus making the process quick, safer, and more effective.


Gas anaesthetics which involves such as sevoflurane and isoflurane can be organized atmospheric used for euthanasia of small animals. The animals are put in closed chambers where high levels of anaesthetic gas are present. Death may also be produced using carbon dioxide at once unconsciousness has been done by inhaled anaesthetic gases. Carbon dioxide is used for euthanasia of wild animals.

Carbon monoxide is also used. However, carbon monoxide poisoning is not specifically painful

Cervical dislocation:

Displacement (fracturing or breaking) of the neck or cervical dislocation, is an older but less common procedure of killing small animals such as mice. If it is performed appropriately it is projected to cause as painless a death. This procedure handler must know the appropriate method of executing the movement which will cause the cervical dislocation and without appropriate training and method education, there is a risk of not causing death.

Intracardiac or intraperitoneal injection:

When IV fluid is not present, then euthanasia drugs such as Nembutal can be injected directly into a heart chamber or body cavity.


Reasons for euthanasia of pets and other animals:

  • Critical illness such as rabies or cancer.
  • Illness or severe accident.
  • Behavioural problems such as aggression.
  • Old age which leads to loss of major bodily actions, resulting in deep impairment of the quality of life.
