By this time, your initial stages of preschool puppy training would have conditioned your dog for a 10 minute walk daily, fetching the toy and also understanding that praise and eatables as reward go together.
When you walk with your puppy you should check whether your their attention is focused on the various sights and sounds around him.
In the event of this happening you should do the following.
Bend to puppy's level, call your puppy by his name and give a "come" command.
Then you pull the puppy with the leash, give him eatables and then shower praises on him.
You should ensure that the puppy is made to obey four "come" maneuvers during the fourth, fifth, sixth and seventh day of daily walk when the puppy is aged nine weeks.
In each "come" maneuver you are required to spend 10 minutes and one tidbit for the puppy.
Why So Many Treats? You might always feel whether it is necessary to reward them one eatable every time the puppy executes the "come" maneuver.
Giving tidbits as a reward for doing something by the puppy will create another problem; you may have to continue giving this reward for future training also without which they may not respond properly.
You should realize that the puppy is in its tender age and can not be trained only by showering praises.
Praise alone can not be the big incentive for the dog to perform.
By the time they reaches the age of ninth week he will be aware that you will not be tossing the play toy for him to retrieve unless he places himself in the sitting position.
In this circumstance the prime motivating factor is toss of the play toy and not the praise showered on him which is secondary.
Ultimately the game should finish with some sort of reward for the puppy and hence you treat them with an edible.
You must realize that at no point of time praise alone can motivate your nine week old puppy; you must give him something more than that if you expect him to obey your "come" command.
If you want your puppy leave his excursion on sight and scent when you command him it is not sufficient if you pat your their head or allow the puppy to continue its walk.
This necessitates giving him a treat in terms of cookies or eatables or any other food items which the puppy likes.
In such a case also the praise is secondary.
You may be able to practice the command "come" on your dog even when there is no school in session; an ideal time for practicing this is the feeding time.
When the feeding time approaches, you must call your puppy by its name while you put his food on the floor.
You should not carry the food to the puppy; you must make the puppy to come to the food using the "come" command.
You should not clutter the mind of the puppy saying "come on boy, it's time to eat" and expect that the puppy will respond.
The word "come" is more than enough to call the puppy.
You may be interested in talking to your puppy to develop his personality and vocabulary; but when you are reinforcing a training response it is better to use only the command word.
