um...no offense, but isn't that dangerous? Plus, what are you going to do if one of your neighbors reports you to the humane society for putting your dog in that kind of danger to begin with?
Therefore, if i were you, i'd just jog and/or walk with your dog instead of doing what you're doing. otherwise, i can only see this working out one or three ways. Either that dog gets accidentally hurt/killed by that car, as he/she could get ran over easily. Or, your neighbors might report you for animal cruelty doing that. Or, it might be a bit of both. Therefore, i'd deeply reconsider this method if I were you...
