Thanks Karen, I have also been and bought some thin rope and attached a little clip to it, so going to take both when we venture into the field, luckily with having horses I have access to a very large indoor school which I am going to take advantage of when I start practising my recall away from home (he is very good at recall at home, but that might change when we go else where) then I will progress to the field as they are enclosed as well.
