Be aware that while you may realize that you're attempting to help your pet, your pet might see this as an attack on him/herself and attempt to defend themselves when they are already in distress. Remember to talk to your pet throughout the entire process in an effort to calm them with your voice.
There are 4 steps you can try:
A. Head Facing downward like a wheelbarrow. Lift the dog by his rear legs to facilitate the object coming out.
B. Sweep from side to side in the animals mouth to dislodge the object.
C. Compress the abdomen by pushing upwards with your fist, much like the human Heimlich maneuver.
D. If the animals head is positioned downward a sharp blow between the shoulder blades will often dislodge an object.
If the animal is TOO Heavy to Lift and is Unconscious:
1. Open their mouth and check for an object, grasp the tongue and pull it forward gently while sweeping with your finger to try to dislodge the object. (Careful, you can still get bitten).
2. If you cannot get the object lay the animal on it's right side.
4. Check the animals mouth again, sweeping, use a penlight if possible to view the object and remove it.
5. Repeat steps 3 & 4 if necessary until the object is dislodged
6. Once the object is dislodged, give 4 breaths to the snout to get the animal breathing, (watch your face, when it comes to it may be snappy).
7. Get the animal to the vet immediately.
