Thanks, she's a fast dog, not so tight turning and sounds like you've got a thoroughbred galloping up behind you, but she's agile all the same.
I know she's a bit different than alot of other RB's I've seen too, but I dont know if thats through exercise, as we're very hilly, and she's up and down steps all day long, or just her stamp....
Still, food for thought for a cross....
