This thread reminds me of a funny story...
My mom-in-law has a chihuahua named Spanky...
Thanksgiving we were all at her house and Spanky barks everytime someone knocks on the door.... Well Spanky had been barking all day as everyone was arriving... he would run to the door and bark... bark ... bark... He is a real friendly dog...but doesn't like anyone he doesn't know. (I think that is a chihuahua trait) Anyway Eric's cousin came over (he hardly ever visits... he is related through marriage) and when he knocked Spanky ran up to the door barking and when John walked in... Spanky couldn't get out of there fast enough... it was so funny cause he was barking like he was big stuff and when he noticed he didn't recognize the person walking in he tried to turn and run and slipped on the tiles and fell then booked it outta there... we were all laughing soooo hard!!!
