Long line lead for mini dachshund puppy?

I have a small Corgi and years ago, I made my own. I bought the hardware and the rope (you can get different types, widths and sizes) from our local home improvement store. That way I got to choose the size and weight of all the components as well as the length of my lead.
I'm still using it after almost ten years.

 

I have a toy Maltipoo and thinking about buying this
