I have a husky and a husky/malamuth. I had the other version more thin and it lasted a year, this one seems more solid. The rope is bigger and the bonus is that the tie that brings the two dogs together turns. No need to untangle the leash when one passes over the other. (also use with other leash).
The downside is that the dogs stay very close, I prefer when they have a little more room. And we can't untie them to keep one leash.
