These are the dog leads I use for my own dog, and recommend to my clients. They are from a company called ‘Mekeet’ and are very durable & comfortable to hold with a handle at the end, and another closer to the attachment.
The lower handle is a very useful option if you and your dog are at the correct distance from each other, and you need to keep your dog close when walking past something that might trigger them.
I have yet to see these leads in a retail outlet, so if you’d like a link to purchase one just let me know
