Which do you think would be better?

I chose B just becaus that is the kind you see more often so they have got to work nicely. Also it seems easier to use with the longer handle. The shorter one doesn't have as much slack for the dog. Looks like you might have to bend down too just to hold on.

See that is the thing with Sheena I will need a longer handle but with Ajax he is so tall I can lay my hand on his back with out bending. So he will need a short handle no matter what. Luckily the handles do come in varing lengths.
