New York animal trainer Lyssa Rosenberg has taught her dog how to read.

Willow, her ten-pound English terrier, can read and obey simple written commands. She plays dead when she sees the word "bang," stretches a paw in the air when she sees "wave" and gets up on her back feet to beg when she sees the words "sit up."

Two pages into The Da Vinci Code, she threw up a little in her mouth.
