Poor puppy! This is one of the all-around easiest to use of the scenarios, which I really appreciated. 

It's well written and easy to understand. The map is smart. The dog is a great idea.

Nice, clear organization, easy to read. Good images – map is clear, extra images work well to set tone. Good adventure, will work even if players have seen the details. (They'll know where the serum likely is, but "in the lab" is not a stretch.)

I love the dog as an antagonist, though. Like that it can be as tough or minor as wanted; this could work as either a gritty space adventure or a comedy romp, if the group wants to push it that direction.
