We are going to judge you extra hard if you use one of these. You know how we feel about flexi-leashes to begin with, so the added “bonus” of a pistol shaped handle aimed at the dog puts this clear into the WTF category. We aren’t sure who this type of thing is supposed to appeal to, but it certainly isn’t us.
Thankfully, this appears to be a concept design only and not actually in production, but we give it 6 months until Hipsters around the world are marching around with these with their ironically named pooch (Chuck, perhaps?) on the end of the leash.
