Mine is always on lead on my usual walk, she's not 1yo yet.
Where I walk near my house there's loads of joggers and cyclists that appear from nowhere at speed, there's quite a few bends and turns lined with huge trees and bushes so you can't see them approaching sometimes.
She's on a flexi which I know people hate but she's really good at coming back on them, if I say "by me" she runs to my side and then I say "keep close" she will walk by the side of me. I use these commands if I see cyclists, joggers, prams, wheelchairs or people walking in general but usually if she sees them approaching she's expecting me to tell her so she will sometimes come back herself.
I'm scared that a cyclist will run her over when they come zooming round a bend is she's off lead.
I don't mind her being off lead in big open fields.
