Raz continued to run, and as he ran, he saw a feeble building, ready to fall into the street, so in an effort to lose them, Raz body checked the building and quickly moved out of th way as it fell just behind him, and he continued to run, or rather wanted to, because when the building fell, debris launched out and hit one of his forelegs and yelped and fell down with a dense thud, but very very slowly he dragged himself away.
A section of the building crumbled down on the far side of the street, the passage barely wide enough for the truck.
