Do you walk your dogs on or off the lead? If on the lead do you stick to a standard lead or use a long line or flexi?

We try to walk our dogs off the lead as much as possible as I think they get much more enjoyment out of it and obviously get a lot more exercise running through the woods or across fields than they would on a lead.

Unfortunatly though a lot of the dogs we board just don't have a good enough recall to be let off the lead so with these we try to give them as much time on a flexi as possible.
