A monkey that one of the protagonists grew attached to is shot and left in front of a veterinary hospital, and it assumingly survives.

Charlie the dog does not die and is not hurt, though he doesn't show up in the second half of the film. A stray dog appears in one scene later in the movie, barking at a sewer grate. It disappears but there is nothing to indicate that anything bad happened to it (it could've just run away).
