If your dog is still fairly alert and not visibly cut or bleeding, construct an emergency stretcher to transport your dog to the nearest animal hospital. A stretcher can be made quickly and easily by taking any poles or sticks and placing them through the arms of a shirt or jacket, or by using a blanket. Use caution in transporting any injured dog, however. Even the most trusting and loving dog can bite if seriously distressed and in pain. If it seems like your dog is really having difficulty breathing you can administer canine artificial respiration.
Brain damage can result if breathing stops for five or more minutes.
Time is of the essence in assessing the situation and taking action. Lay your dog on its side, check its mouth and remove any mucus or other foreign matter by using your finger wrapped in the cleanest cloth or tissue available. Push down gently on your dog's chest behind the elbow. Apply pressure for a few seconds, then release for a few seconds. Continue in this manner until your dog begins breathing again.
