Inca (aka Full Steam Ahead) is happiest when she's on the move. Sitting still for more than five minutes simply isn't in her vocabulary. Whether she's trailing a scent, searching a field or charging through the countryside, she's fast, tireless and always ready for work, whatever the weather. Her other great love? Tennis balls.  When she's finally persuaded to slow down, Inca transforms into a cuddle monster on the sofa. She's also convinced that every meal is her last, switching from fast asleep to "did someone say food?" in the blink of an eye.
