Rain, Rain Go Away

Alvin, my little male chihuahua, has learned to ring the bells hanging on the door knob when he wants to go out.  He is so smart!  So today was rainy.  All day long.  Alvin rang the bell.  All day long.  And every time he did, Addie, my little female would come running.  She is trained to know the bells mean outside but refuses to ring them herself.  I constantly put their little raincoats on them, let them out, let them in, take off their raincoats.  Over and over again, all day long.  Now they need rain boots so my floors stay clean on these rainy days!  Here's a picture of them.  Aren't just adorable?
