How did dwarves respond when Bilbo asked for volunteers to accomany him into the mountain in The Hobbit?

The reacted excitedly, as dwarves in Tolkien's epic tale
were known as miners, and controlled the Mines of Moria for generations.  So the Dwarves
expect to reuinte with family and friends, expect to feel at home in the mines, and to
introduce Bilbo around and spend nights of feasting, drinking and storytelling.  They
are, of course, disappointed to find the mines all but
abandoned.

It is Tolkien's way of foreshadowing the future
books in the series and illustrating that Middle Earth has changed, and was changing. 
That the danger was real and present.
