The truth is: If it is the law and you allow your dog off leash, you are breaking a law. In a civilized society, members do not simply pick and choose which laws apply to them. I repeat this mantra: It does not matter that you perceive your dog to “be friendly” or that “he loves other dogs.” It does not matter because the dog you have no voice control over is hurling himself into the faces of dogs who very well may NOT be friendly to other dogs. Your dog galloping right up to a leashed dog is rude canine behavior, even if you are running behind your dog screaming: “Don’t worry! He’s friendly!!” You endanger your own dog and all those you allow him to terrorize or bother.
This inexpensive leash is billed as "indestructible," and this pick was a favorite of our consumer (and K9!) testers. Users raved about the reflective material and thickness of the leash, confident that it could hold up to even large dogs' pulling. Testers also loved the look and security of the clip, although it may be a little large for small dogs. 
Consider why puppies pull when they are walking; there are many things that tempt your dog when you’re out for a walk, like children playing in the yard across the street, you neighbor grilling some hot dogs and that squirrel in the tree at the park. Your pup will try to get where he wants to go, even if that means pulling you along with him! If he pulls on the leash and you allow him to, you’ve reinforced that pulling gets him what he wants. Once you’ve allowed him to do this, he’ll do it again and again:
