To evaluate and assess an emergency situation with a dog use the ABC principle for CPR:
A Airway – is there an open airway? Check for any signs of obstruction, open the dog’s mouth and pull the tongue forward.
B Breathing – is the dog breathing? Observe the chest for any movement, observe the rate, depth and effort. Place a hand on the chest to feel for the rise and fall on breathing in and breathing out.
C Circulation – is there a heart beat and pulse? Check the dog’s heart rate and rhythm, plus the pulse rate and quality.
