Except how does one distinguish between marking in the house and potentially serious bladder and/or kidney issues? If someone has a dog with issues like my Simon's where he's having accidents, but wasn't an overly hyper dog mom, couldn't they conceivably put something like this on them and then miss the underlying problem entirely? I'm a firm believer that dogs don't *just* mark in the house because it suits them - in fact, I don't believe that dogs *just* do anything for the heck of it. This seems rather medieval in a day and age when you've got wonderful health and training resources - paid and free (like this site) and yet one would have to resort to something as barbaric as essentially tying a dog's penis to it's belly. Normally I'm right there with ya LR, but this time I have to respectfully disagree
