feist

(fīst) also fice (fīs)

noun
Chiefly Southern U.S. Regional Note: Feist, also fice, is one of several regional terms for a small mixed-breed dog. Used throughout the Midland and Southern states, feist connotes a snappy, nervous, belligerent little dog—hence the derived adjective feisty, meaning “touchy, quarrelsome, or spirited,” applicable to animals and to people. Although feist remains a regional word, feisty has now entered standard usage throughout the United States.
