“Once Bitten, Twice Shy” – Dogs and Mustard!

Illustration:  "Once Bitten, Twice Shy." From:
“Once Bitten, Twice Shy.”
Mary Had a Little Lamb and Other Good Stories.
Henry Altemus Company: Philadelphia. 1906.

A burnt dog dreads the mustard pot;

However you may try

To coax him, he will taste it not –

Once bitten is twice shy.
