There are many acceptable routes of euthanasia solution administration in companion animals. The most common ones are those with consistent use and success, and that align with what is best for the patient, client, and veterinary team. Common injection sites include the venous, hepatic, and renal systems. The barbiturate drugs are in consistent use today, but other drugs may be better given the setting and circumstances at the time. Alternative techniques are available, but only reached for when other more suitable routes of administration are not ideal.
