Do I need one? Pup is 19 weeks old recall is good but I only let her off in a quiet field away from other people/dogs so I'm not naive to think she may be distracted and not come back in different circumstances or when she hits adolescence, so should I get a long line?
Are they a trip hazard/prone to tangling up? How long should I get as I don't want to be reeling in loads of lead?! What thickness/material I've seen rope ones, nylon ones and rubbery ones... Amazon has too much choice!!
