Conversely, this could result in your dog becoming disobedient and spoiled as he grows older with a lot of major behavioral issues that are so much more complex in changing since he has aged and his routines are concrete. A prime example is training your dog for a leash. When your dog is a puppy and still developing his size and strength, leash training requires significantly less effort on your part. Quite simply, once any dog matures, their strength can be used at full force to direct you where they want to go, versus the other way around. The owner and pet will become increasingly frustrated, making leash training more complicated.
The Process
Every new puppy needs to get accustomed to wearing a collar around his neck; this is the first hurdle to accomplish when leash training your dog. Once you have the puppy familiarized with his collar, he will probably try to get rid of it by scratching, biting, rolling about or trying something similar to that. Even as this may be hard for you to watch, avoid taking his collar off until he has relaxed a bit and his attention is diverted. He needs to learn that the collar cannot be removed, so make sure that it fits comfortably, yet is still snug enough that he can't pull it off himself or by pulling when on the leash.
Your next step for training your dog with a leash is to use the leash in a similar process. You can snap the leash onto his collar and let him run around the house playing while wearing it, just let him get used to the sound and feel of it on him. Just like with the collar, he will soon forget that he even has the leash on, and won't object to you putting it on him again in the future. One of the most crucial aspects to take with this step is to never leave a puppy by himself while he has that leash on, as this could result in injury or even death lest something goes wrong.
Step Three: You need to get puppy used to the feel of you holding the end of the leash, so it's a good idea to put it on him and walk around the house with him awhile. It is important to leave enough slack between you and your dog, as this allows the puppy to walk alongside his master. If the puppy should begin to tug his leash, the owner ought to halt in his walking right away and call the dog's name to bring him back to his side. As soon as this is accomplished, the owner will be able to commence walking once more and continue to do so as long as his dog heels with his leash hanging loosely at one side. Whenever the puppy is walking next to you and not pulling, provide an abundance of praise to positively reinforce his good behavior. It will encourage him to keep it up, as dogs strive to please their owner.
