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:

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. 
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 your pup barks: Some dogs have the habit of barking at other dogs while on a walk. Oftentimes, this behavior comes as a result of lack of exercise. Make sure your dog gets the proper amount of mental and physical stimulation for his age and breed. If this is still a problem, use the same process as you would if your dog is lunging, as described above — create distance and offer treats before he starts to bark, so every time he sees a dog he gets used to turning his attention to you.
Some prefer a plastic stand because of its lightweight and portable makeup. For apartment dwellers especially, a product made of this material is great for toting up and down staircases or on cross-country moves. When it comes to the best plastic stand to go with, the Jack Post Handythings model is an excellent choice since it only weighs a total of three pounds.

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.
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’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.
