The main idea is that in the city there should be much more zombies, which are unlikely to allow a retreat to a safe distance. Also, an explosion of fat zombies will attract even more zombies. And we always can fix him.
Ohh okay, here you right. I incorrectly described my thought. Zombie dog needs to enter two modes, the first - it slowly walks around the city second - it saw the player and began to run after him at a speed slightly higher than that of the player
