Term used to describe the sudden, unexpected behavior of a Jack Russell Terrier. Without notice or provocation, they streak about the house as if on a race track. Often noted to stop as unexpectedly as it started.
Otis and Kira were a blur as they ran from the kitchen to the living room and back again on the invisible race track only they could see. Jack Russell Turbo needs not be defined once it has been witnessed.
