Dog leashes are used to walk the dog in public places. Having the dog wear a leash is a way of protecting the dog and other persons (e.g., if the dog runs away and bites someone). Also, the length is one of the important aspects of the leash. The length of the leash must be chosen according to the size of the dog and it is important because it allows a good control. Leashes should not be either too long or too short. Too long leashes do not provide good control of the pet which can result in unpleasant accidents with more aggressive dogs whereas too short leashes are uncomfortable for both the dog and the owner. The perfect leash can restrain the dog but at the same time is not viewed as a punishment for the pet.[9]
States that do not have statewide leash laws are Alabama, Alaska, Arizona, Arkansas, California, Colorado, Florida, Georgia, Hawaii, Idaho, Iowa, Kansas, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Montana, Nevada, New Jersey, New Mexico, North Dakota, Oklahoma, Oregon, Rhode Island, South Carolina, South Dakota, Texas, Utah, Vermont, Virginia, Washington, and Wyoming.
High quality dog leashes have a good quality metal clip and they can be made of leather, nylon or even chain. The metal clip must securely fasten to a metal ring on the collar in order to maintain good control of the dog.[10] The material of which the leash is made of is not of great importance as long as the leash does not show evidence of wear or fraying. Therefore, leashes should be periodically checked to ensure they are maintained in proper condition.
Or maybe, you have an older dog that walks you instead of you walking him. He pulls you all over the place, chases the neighborhood cat into the thorn bush up the street that you are now well acquainted with, and it seems like any time you pull back on the leash, Fido increases his speed! You decide he’s getting too big or too strong for you and before you know it, you are in traction at the chiropractor and your beloved pup is getting fat on the couch!
I mean, have you ever seen anyone successfully loose leash walk their dog using a retractable leash? I observed a man yesterday at our local pet food center trying to control his medium sized dog while another customer was walking their very petite pups. Guess what he was using? A retractable leash, that malfunctioned, the dog was able to get far enough away from the owner that he lost control and the dog went right after those little puppies. Luckily, the dog just wanted to say hello, and those two little pooches knew exactly how to take care of themselves! This scenario could have turned out pretty bad.
This type of training is more effective because it builds a bond of trust and cooperation between animals and humans, the animals (and the humans) actually look forward to training! No one looks forward to punishment, or even the probability of punishment!  We all want to be told when we do something right, not belittled, hit or corrected when we do something wrong!

Daily exercise is a must for dogs of all shapes, sizes and ages. Finding a well made, durable leash that’s comfortable for both you and your pet is key to keeping your dog active and happy. Even if you have a large, fenced-in backyard, walking your pup around new places gives him a chance to explore and helps to socialize him to other humans and other dogs. While you may consider a leash a simple purchase, finding a leash that best suits your dog’s needs can be a tall order. Whether he’s a puller or a runner, we’ve sifted through the options and found the best products for every type of dog.

He has also trained at the famous Vohne Liche Kennels with owner Ken Licklider, which the Nat Geo show “Alpha Dogs” is based off. Vohne Liche Kennels is the training hub for the military and DoD special forces K9s. Last year, Nick was made part of Sport Dog’s Pro Staff, as he was considered to be one of the top electronic trainers in the world. Nick will be appearing on “Alpha Dogs”.
If your pup lunges: If your dog is going after something while on a walk — another dog, a car, a skateboarder, for example, be proactive. Try to redirect his attention with a treat before he has a chance to lunge, and increase the space between your dog and the target. Stay alert and be prepared before the target of his frustration gets too close. This type of behavior may be more common in herding breeds, but any dog can be startled by something he’s not used to or finds exciting.
Purposes of a leash include: preventing animals from frightening or biting people or other animals, defecating and urinating in inappropriate places, endangering traffic, digging up lawns, causing other damage, getting lost, and getting away from owners. Leashes also provide a clear method of communication and ensure control during training of dogs.
Speaking of reward, positive reinforcement refers to operant conditioning, and I won’t bore you with the details right now, but suffice it to say B.F. Skinner, one of the leading researchers on reinforcement, found that positive reinforcement (to reward good behavior) is far more superior to punishment in altering undesirable behavior because positive reinforcement results in lasting behavioral modification, and punishment changes behavior only temporarily; and presents many detrimental side effects. If the problem behavior changes temporarily, it will reappear later, and it comes with even more problem behavior! Good Behavior = Reward and Bad Behavior = Punishment, does that sound familiar? Positive reinforcement training is what exotic animal trainers have used for years to teach dolphins, whales and large cats among other animals.  You cannot force a dolphin to do what it does not want to do!

Now, you may begin allowing your pooch to wear them around the house, increasing the wear time. Keep your pup inside with you, during the beginning of training to help him be successful (training outside can be distracting), and click and reward every time he chooses to be near you while he wears the collar and leash, and remember, consistency is key here. Also click and reward if he looks up at you, this is the foundation to getting his focus-You want his attention to be on you!
If you have a super strong pup on your hands and lots of room to walk, this leash might be for you. This sturdy rope leash comes with a shock-absorbing bungee cord extension that adds extra give for dogs who want to drag you down the street. While we wouldn't recommend using it in busy areas or with dogs who are prone to bolting, it can help make walking stubborn pullers more pleasant.
