The dog collars, harnesses and dog leashes available at Petco can help make sure your pup stays safe as they master the art of leash training. Our selection of sizes, styles and materials allows you to choose your dog’s accessories based on your functional need, style preference or a mix of the two. From durable nylon dog collars and step-in dog harnesses, to fashionable leather leashes, you’re sure to find a mix that fits their needs and your personality. You can also indulge in your pet’s fashionable side by getting them a matching dog collar and leash.
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.

Leashes are used on large animals—such as bovids, camelids, and equids—to lead them so that they will be forced to follow and come to a desired area—as well as to tether them to a specific area, such as to a fencepost or tree trunk, so that they will remain stationary and not run away. Oftentimes, leashes are used to tether such animals when they require separation, examination, or work to be done to them, such as grooming and tacking up.
Even though your puppy may be learning to walk on a leash very nicely, you’re likely to run into some issues as he gets older, goes new places, and experiences new distractions. You’ll want to teach him loose-leash walking, because it’s much more pleasant for you both, and also then he can pass his Canine Good Citizen test. Here are a few tips on what to do if you’re having trouble with leash training, courtesy of the AKC GoodDog! Helpline.
Throw a meat treat in the direction of the oncoming dog, turn on your heels, and walk away. I cannot even count the number of dog owners who are shocked that as their dog is being harassed by the off-leash dog, the owner of stands there, saying nothing, and doesn’t help to put an end to the situation. If another person is walking with you, ask them to attempt to catch the oncoming dog as you leave the scene (you have to decide in an instant if that would be a safe maneuver or not because breaking up a dog fight is an excellent way to get bitten).
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. 
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.
In Delaware, dogs are not allowed to run at large unless in situations when the owner is present and has control over the pet. An exception is for farm dogs. Also, during the night dogs must be kept in an enclosure from which they cannot escape, firmly secured with a collar or chain or other device, so they cannot stray from the premises,[3] or are under the reasonable control of the owner or custodian. If an owner does not respect these laws and if the dog bites someone, the owner is subject to civil liability and for fines of up to $1,500.
This leash comes with a comfy padded handle and ring for waste bags, giving you and your best friend the perfect set-up for a long walk. It comes in a variety of lengths, and shorter leashes work great for crowded urban areas or anywhere you want to keep your furry friend close. A swivel clasp at the collar end gives your dog plenty of mobility, and double-woven nylon will last for years. 
Leash walking outside may be more frustrating because there are numerous distractions for you to compete with for your puppy’s attention. Understand, from his point of view, how much more difficult this task has now become, and whatever you do, don’t lose your patience; don’t drag him or allow him to drag you! Walk slowly and click and treat if he stays at your side. If he begins to pull, stop or change your direction, then click and treat when he reaches your side again!
Cat leashes are used with the purpose of preventing the cat getting lost. Unlike dogs, cats rarely attack persons on the street, so cat leashes are mainly a safety measure to protect the pet itself. Very often the collars are replaced with harnesses, because they avoid the dangers of collars which include escaping and running away or choking. Cats are more likely to not be willing to be walked in a harness than dogs are, and are considered to need up to months to be able to adjust to wearing a harness.
The clicker is a very effective training tool, that when conditioned with a reward like food, a treat or a toy signals to your puppy that he has done something right.  The clicking sound becomes synonymous with the reward/treat once training has begun. However, your puppy has to be taught that the clicker means something and clicking alone is not reinforcing anything.
If you’re looking for a leash that’s easy on the wallet, safe and durable, the Blueberry classic leash is a great choice. We love that it comes in 12 different colors and five sizes (ranging from four to five feet in various widths) so that it can work with nearly any dog. If your dog is easy on the leash and doesn’t require a lot of control or guidance, a standard nylon leash will do the job. We recommend this leash for dogs 75 lbs and under, as larger pups may need a stronger version.
