Police Dog Performs CPR

This is the impressive moment an adorable dog wearing a flashing police light 'saves' the life of his trainer by performing CPR.

In the clip, filmed by the Madrid police, the police officer dramatically falls to the ground before lying down and staying perfectly still.

The tiny pooch, named Poncho, then runs over to his fallen comrade straight away and tries to wake him up by pushing his side.

When he doesn't move, the dog jumps up and down on his chest four times before placing his ear next to the police officer's mouth to listen for breathing.

After doing that, he goes back to jumping up and down before repeating the move once again.
