Answer:
I go from house to house a messenger small and tight. Whether it rains or snows I sleep outside at night.
What can you catch but not throw?
With a halo of water and a tongue of wood; stone as skin long I stood.
I make a loud noise when changing jacket. I become bigger and delicious.
I will disappear every time you say my name. What am I?
Runs over fields and woods all day. Under the bed at night sits not alone, With long tongue hanging out, Resting at your feet until we go for a walk
