What is Lennie eagerly talking about toward the end of the chapter 2 of Of Mice and Men?

has just
overheard Slim tell Carlson that his dog, Lulu, has just given birth to some puppies. Slim has
drowned four of the nine because nine is too many for Lulu to nurse. Slim is keeping one for
himself.

Lennie, who loves animals, is looking excitedly at . George says he
will ask Slim if Lennie can have a puppy:

A brown and
white one, Lennie cried excitedly.

George responds that
he isn't sure a brown and white one is available. Lennie persists in asking George to find out
about a puppy, fearing that Slim might decide to drown more of them before Lennie can get one.
George says he will and then urges Lennie to get off the bunk so they can go to dinner as the
meal "triangle" has sounded.

Lennie's excited conversation about
and desire for a puppy is juxtaposed with worrisome appearances by Curley's wife and Curley in
the bunk house. Both George and Lennie get a bad vibe from Curley and his
wife.
