Even before finding their destination, Ryan already knew a few things about that army of monsters that was heading West. First of all, the Werewolves were tier two monsters. That being said, Ryan couldn't underestimate them. Given the fact that he never heard of them, they weren't ordinary monsters, and also, given their skills, he couldn't attack them. If he does that, Ryan won't find their dungeon. He tried to find anything that resembled their dungeon, but he didn't find anything.
Second of all, it was obvious that those dogs were working for a few dungeon masters that decided to make an alliance. It was weird to make an alliance when they were on Earth, but it wasn't made to wipe out the remaining humans. If that were their goal, they wouldn't move toward a location in the opposite direction of the only human settlement in the country. They would split and attack from all sides.
