Trixie Extra Light Tracking Lead - Graphite

I ordered this because the public area supervisors in our village have started cracking down and fining dog owners who walk their dogs without a lead. Our golden retriever walks right by my side at my pace without a lead, is friendly with people and other dogs but not pushy, comes when called, and if he sees a cat, a simple "no" is enough and he won't chase after it. However, on a short lead, he can't do his business properly. It's a bit tricky to adjust the lead to the right length, because our dog isn't used to being 15 metres away from us, only when he's playing.
