Is dog euthanasia painful? Dog euthanasia is not painful. During euthanasia, dogs usually do not feel pain except for the stinging pain of the injection. When a dog is suffering from an incurable disease and has to endure pain that cannot be controlled by medication, the owner will usually cooperate with the veterinarian to euthanize the dog. Dog euthanasia is mainly for dogs with poor quality of life, serious illness, old age and infirmity, and only dogs that meet the criteria can be euthanized. The medication used to euthanize dogs is usually potassium chloride or sodium pentobarbital.
