Sparrow is a very hard driving, focused leader with endless energy. Never seems to tire, very heat tolerant, and is always raring to go, even when there is no bottom to the trail. She charges through chest deep running water with ice chunks floating it, over 8 feet high snow banks to find the trail on the other side, always goes no matter what, just an awesome dog!! Great eater, great feet...and incredibly athletic! Sparrow is one of our best producing females and is also my main leader. Most of the kennel is out of her and she has grand pups and great grand pups!!!
