Before administering any first aid, make absolutely certain your pet is actually choking. Many people confuse difficulty breathing with choking. If you witness your pet ingesting an item and then immediately begin pawing at the face, the throat, acting frantic, trying to cough and having difficulty breathing, only then should the Heimlich maneuver be considered. If your pet is not really choking, the Heimlich can cause serious injury.
After determining that your pet is choking, remove any item that may be constricting the neck. Examine inside the mouth and remove any foreign object you see. Do not blindly place your hand down your pet's throat and pull any object you feel. Dogs have small bones that support the base of their tongues. Owners probing the throat for a foreign object have mistaken these for chicken bones. Do not attempt to remove an object unless you can see and identify it.
If your pet is small and you cannot easily remove the object, lift and suspend him with the head pointed down. For larger animals, lift the rear legs so the head is tilted down. This can help dislodge an item stuck in the throat.
Another method is to administer a sharp blow with the palm of your hand between the shoulder blades. This can sometimes dislodge an object. If this does not work, a modified Heimlich maneuver can be attempted. Grasp the animal around the waist so that the rear is nearest to you, similar to a bear hug.
Place a fist just behind the ribs.
Compress the abdomen several times (usually 3-5 times) with quick pushes.
Check the mouth to see if the foreign object has been removed.
This maneuver can be repeated one to two times but if not successful on the first attempt, make arrangements to immediately take your pet to the nearest veterinary hospital.
Even if you are successful in removing a foreign object, veterinary examination is recommended. Internal injury could have occurred that you may not realize.
