Hello people! I've been pondering about if I should get myself a coupler for my dogs. Walking with many leashes is uncomfortable for picking up poo and that kind of stuff. Do you have any experience with them? Right now I have a dog that is leash trained and another one who is not. Do you think it would be detrimental for my dog's education? I'm not very good at physics so I'm not sure how the tension on the couplers would work and how it would affect the individual dogs. Sometimes I grab both leashes and use my hand to keep them together, while holding the rest of the leash in the other hand, and it works fairly fine (until I need to pick up poo), but of course if a dog pulls, the other one doesn't get any kind of tension from it since a totally different leash. Thanks!
