Lily the Lost Puppy (Puppy Friends #2) by Jenny Dale

Everyone loves puppies!
Bouncy and cute, 
furry and huggable,
what could be more
perfect than a puppy tale?

Lily's family is moving house.
Jack, Lily's owner, tells her all
about their new home.

Then something terrible happens.
Lily's family leaves her behind
by mistake. Will Lily ever
see Jack again?
