Choking Dog Heimlich maneuver
If your SAR dog should have
The explanation here is for a medium to large sized dog.
Wrap one arm around the dog letting the head, shoulders and forearms hang forward. Then close your hand forming a fist and close your other hand around this fist. Position your fist between the dog's navel and rib cage and then quickly and powerfully thrust inwards and upwards. Do this as many times as is necessary to dislodge the blockage.
By pressing in and up just under the dog's diaphragm you will be compressing the air in its lungs and forcing it out through its mouth which should also eject the foreign object. If your SAR dog is still not breathing once you have removed the object then begin AR (artificial respiration) and if it has no pulse then immediately begin CPR (cardio-pulmonary resuscitation). Seek immediate medical attention.
