On sizing
20kg is the top of this case's rating, not a figure with headroom built in - a strong-pulling dog near that weight will feel the brake working harder than a lighter dog would. If your dog pulls hard rather than walks loose, consider the next case size up.
Why we chose it
Matching the case size to the dog's actual weight, rather than buying whatever's cheapest, is what keeps a retractable lead's brake reliable - and this is the size flexi build specifically for a proper medium dog. The colour options are a small thing, but useful if you're walking more than one dog.

Full description
A medium dog on a retractable lead pulls with real force behind it, which is why the case size and the weight rating on one of these matter more as the dog gets bigger.
This is flexi's medium-cased Black Design cord lead: a 5 metre cord rated for dogs up to 20kg, with the same braking system that runs through the rest of the Black Design range, and a case that can be fitted with flexi's own Multi Box or LED Lighting System.
- 5m cord lead
- For dogs up to max. 20kg
- Comfortable braking system
- Size MED case
- Can be customised with flexi's Multi Box and LED Lighting System
- Available in black, blue or pink
On sizing: 20kg is the top of this case's rating, not a figure with headroom built in - a strong-pulling dog near that weight will feel the brake working harder than a lighter dog would. If your dog pulls hard rather than walks loose, consider the next case size up.
Who it's for: owners of medium dogs, up to 20kg, who want the reach of a retractable lead with a case built for their size rather than a smaller one stretched to its limit.
