1. Examination of breathing: Put your hands in front of the dog ' s nose, try to feel the air, or check if his chest is up and down. If the dog does not breathe, check if it's blocked in its mouth and pull its tongue forward.
2. Examination of pulses: Hold the dog ' s toes and feel his or her movements or touch the position of the root in the back leg of the dog. If your dog has a pulse but does not breathe, it needs artificial respiration.
3. Immediately after the emergency rescue, it needs to be sent to the pet hospital for systematic rescue, to find out why the dog was in a bad mood and to rescue the dog for the reason that the owner himself had no professional equipment to inspect the dog at home, so it is best to send the dog to the pet hospital for examination and treatment immediately after the simple rescue.

Hint:
Dogs are not breathing and are soft, usually because they are poisoned by eating food, or because of disease, so the master regularly takes the dog to medical check-ups to prevent problems in the dog ' s body, and is not allowed to feed indiscriminately to prevent the dog from dying from poisoning.
If the dog was shivering and breathing, it might have been a shock, and it needed to be comforted. Maybe it's cold, keep the dog warm. It is accompanied by physical pain and can check if the dog is injured. There may also be physical conditions, such as epilepsy, encephalitis, canine plague, etc., requiring a dog to be diagnosed. Last one. Next one.
