I think Harlee would be cautious...yet if an animal (mainly cat) crossed the road and went into a field...so would she. I also think of her as being heavy on the brakes...kinda like gas,brake, gas, brake, etc. Since she is a Swissie...she is kinda big and clumbsy when she runs (gallops)...so I think she would be a sudden braker, and then speed up reall fast and then brake real hard , LOL
