Poncho, an eight-year-old cocker spaniel, went viral thanks to his life-saving CPR skills. At a display of police dog skills in Madrid, the dog ran to his partner when he collapsed lifeless on the floor.

The dog quickly began CPR, leaping and thudding onto the officer¡¯s chest and even nestling his head onto the fallen policeman¡¯s neck, as if he was checking for a pulse.

Poncho repeated the procedure until his friend revived, and the crowd roared with applause.

Difficult words: CPR (cardiopulmonary resuscitation – making the heart and breathing work again), leap (jump up high), thud (move, fall down), nestle (put something closely), revive (bring to life again), roar (be loud).
