@Setanta,
She'll get there.
It is very different walking a small dog, I find. 99% of the time I walk dog/s that are about waist height, and a very short lead is easily achieved.
The very rare times I walk a small dog, I immediately notice that the short grip is impossible and that extra foot or so can easily lead to the little dawg shuffling a few feet right or left of line.
Is there a knack to it, Set?
The worst one I ever walked was a little female staffy, who was low slung, as strong as a train and had no idea of direction.
By the end of the walk, my arms had muscles on their muscles.
