Drugs for dog euthanasia

1. Inject potassium chloride: use 10% potassium chloride injection at 0.3 to 0.5 ml per kilogram of body weight for rapid intravenous injection, causing instantaneous hyperkalemia and high concentration Potassium ions can cause heart conduction block, weakened contractility, and finally inhibit the myocardium, causing sudden cardiac arrest and death. This method only shows a very short period of muscle stiffness throughout the body and then becomes flaccid and dead.
2. Oral sleeping pills: Oral sleeping pills are taken to put the sick pet to sleep, and then a central anesthetic with respiratory depression is injected. The anesthetic here usually refers to some powerful sedative drugs that can cause suffocation. Injection of powerful anesthetics suppresses the sick pet's respiratory system and eventually causes respiratory arrest and death.
3. Inject coagulant: First let the sick pet fall asleep with an anesthetic, and then inject coagulant to block the veins. The main mechanism of action of coagulants is to act on the coagulation factors of blood proteins in the animal body, causing blood coagulation, forming thrombus, causing obstruction of blood vessels, blocking blood flow, and causing the death of sick pets.
4. Injection method of sodium pentobarbital: rapid intravenous injection of 15 ml per kilogram of body weight or 75 mg per kilogram of body weight.
5. Injection of saturated magnesium sulfate method: rapid intravenous injection of 40% magnesium sulfate solution at 1 ml per kilogram of body weight.

Situations when dogs need euthanasia

1. Dogs are often euthanized because they suffer from a disease that is difficult to cure and will not die immediately. The diseases the dogs suffer from cause the dogs to suffer immense pain, such as being unable to eat, sleeping poorly, and being paralyzed on the ground, moaning in pain. For example, a dog's trauma caused severe paralysis of its limbs and it was in a critical state. Therefore, the owner could not bear to see his dog suffer such pain and chose to euthanasia. There are also dogs with rabies, some dogs with distemper, etc. that may be euthanized.

2. Some dogs need to be euthanized because someone abandoned them at will and allowed them to breed freely. Later, because no one adopted them and the community could not bear too many stray dogs, they were euthanized. The problem of stray animals. There are also individual examples such as: someone in the family is planning to get pregnant and have a baby, and the owner takes him to the hospital and asks the doctor to euthanize the dog. Because the dog may carry Toxoplasma gondii, which can cause miscarriage in pregnant women, the owner usually takes the dog to the hospital during pregnancy. Pet dogs are not allowed. However, a very small number of people will choose to euthanize their dogs because someone in their family is pregnant, and they usually give the dogs to others.

The process of pet euthanasia

In order to allow dogs to die truly peacefully, the sodium pentobarbital method is generally recommended abroad. Sodium pentobarbital is generally used in animal anesthesia experiments. Animals will quickly become drowsy and anesthetized after being injected with sodium pentobarbital. When used in large doses, it will inhibit the animal's breathing, and eventually the animal will die due to respiratory paralysis. Injecting sodium pentobarbital does not cause significant pain to dogs, so many organizations and owners choose this method. saturatedThe magnesium sulfate method is another method that will not cause the dog to struggle and die quickly. The principle is that magnesium ions have the effect of inhibiting the central nervous system, causing loss of consciousness and directly inhibiting the respiratory and vasomotor centers of the medulla oblongata. It also blocks the conduction at the junction of peripheral nerves and skeletal muscles and relaxes the skeletal muscles.
Editor’s reminder: When you have to take your dog to a pet hospital for euthanasia as a last resort, you must clearly instruct the medical staff to inject anesthetic first and then potassium chloride, because the cost of anesthetic is relatively high. Especially for imported anesthetics, in order to save costs, some small hospitals use very small amounts of anesthetics, or do not use them at all, and just administer potassium chloride intravenously.
