a proof that there is a den in a stranger wolf territory

LOOK, I HAVE JUST MADE THIS RANDOM THOUGHT. IN SLOUGH CREEK MISSION #6, YOU WILL HAVE TO GO TO A SUMMER DEN, WHICH IS JUST A FLAT PIECE OF DIRT GROUND WITHOUT A DEN SO.......... A STRANGER WOLF TERRITORY DO NOT HAVE ANY DENS OR PUPS IN IT BUT IF YOU GO AND COME BACK, ANOTHER WOLF WILL BE STANDING WHERE THE OTHER WOLF WAS STANDING SO COULD THAT WOLF BE ONE OF THE STRANGER WOLF`S PUPS THAT HAS GROWN UP? THERE IS NO CAVE OR TREE LIKE DENS IN THE TERRITORIES SO COULD THE TERRITORY BE A SUMMER DEN PLACE??????
