Death by asphyxiation is one of the primary causes of death amongst. This problem can often have a positive outcome if there is a correct and adequate response. Remember that the body's organs have only a limited reserve of oxygen and without swift intervention the dog could suffer irreversible brain damage or even death. Make sure that there is nothing blocking the dog's airways and that it can breathe freely. If it is not breathing then you must begin artificial respiration immediately and if there is no pulse then you should begin CPR (cardio-pulmonary resuscitation) on the SAR dog. Seek immediate help from your veterinarian or local emergency clinic.
