What is the correct technique for chest compressions on a dog in cardiac arrest when no internal defibrillator is available?

• A. Place one hand over the other on the widest part of the chest, compress at 100–120 per minute to a depth about one third of the chest, allow full recoil, and perform rescue breaths (30:2 ratio for adults).
• B. Use both hands on the tail, compress at 50 per minute, depth one quarter of chest.
• C. Pushing on the neck, 200 per minute
• D. Just rubbing chest gently with two fingers.

Answer: (A)

The essential idea is delivering effective chest compressions to sustain blood flow during canine CPR when no defibrillator is available. Position your hands on the widest part of the dog's chest over the sternum, using both hands to press straight down to a depth of about one third of the chest. Maintain a rhythm of about 100–120 compressions per minute and allow full chest recoil after each compression so the heart can fill again. When possible, pair the compressions with rescue breaths to oxygenate, commonly described as a 30 compressions to 2 breaths rhythm. This combination focuses on generating circulation and oxygen delivery until advanced help can be provided. Pushing on the neck, compressing the tail, or simply rubbing the chest with two fingers would not produce the necessary chest compression to move blood effectively, and would not maintain perfusion.
