all i'm saying is that i've gone through no less than three different types on a 16 pound dog - they have all broken, tangled, not worked when i needed them to, etc. the wider belt ones pose less of a hazard of cutting but it is still there and i've seen it happen. i'm not saying my experience is everyone's, certainly, but yeah. i just personally prefer wrapping a leash around my hand and letting it out more or letting my dogs off leash when it's safe that way.
