Having the power to “baby a puppy” you just took home because its so tiny and adorable can be very tempting. But you have to remember that by doing so, this may lead to an untrained pup and a spoiled dog that will have a lot of different behavior problems in the long run. If this is the case, it will be hard to retrain a dog if he's already aged and is used to certain patterns already.
Dog leash training is one of these behavioral issues. When the dog is still a puppy it would be best to train them with a leash as they are still small and are easy to control. It is harder to train an older dog with the leash as they are heavier and will be more able to pull the owner around and cause troubles.
Steps
The first step to dog leash training is to get the new puppy used to wearing a collar. When a collar is first introduced to the puppy, he will most often try to get it off of his neck by scratching at it, rolling around or use other means to try and remove it.
It is going to be complicated to watch this whole procedure but you have to control yourself and remember that you are not to remove the collar until the time that the puppy has relaxed and becomes preoccupied with something else. This way, he would realize that no matter what behavior he shows he can not have the collar removed and that his collar can come on or off any time.
The next step in dog leash training is to do the same sort of process with the leash. The leash should be attached to the puppy's collar and the puppy should be able to drag it around with him while he is playing.
Before long he will not remember that there is a leash attached to his collar and he will likely forgot about it. At this point the owner can move to the next process. One important safety measure with this method is to not leave the puppy with the leash hanging around his neck while unsupervised as he might get caught on something which could be dangerous.
The final step is for the owner to train the dog to be comfortable having someone hold the end of his leash. The owner will need to walk around the house while holding the dogs leash. The leash should stay loose between the owner and the puppy so the dog is always by the owner's area. If the dog tries to pull his owner, the owner must stop walking and call the dog so the dog will know the owner is in control.
As soon as this happens, it would be safe for the owner to start walking again just as long as the puppy stays at the point where the lash is hanging freely. The puppy must be commended from time to time if he is doing well so that he knows that it is a pleasure walking that way.
