It's clear that the most vital things for a puppy are games and joy. Nonetheless it is also important to show him their limits. In troops old dogs are responsible for making the youngest to understand this. At home this task is on your shoulders.
You should taboo to a puppy the things you don't want to see in adult dog. A puppy in bed? Nothing terrifying? And what will you say if there is a fifty-kilogram hefty fellow? Lying in bed and on the table, biting and tearing clothes and shoes, scratching the door, skips and leaking, begging and chewing - owners often remit these to their puppies. Let the naughty dog understand you won't admit this. This is not the question of punishment. One should just explain. Foster a dog by means of voice - a dog does understand it. Loudness means nothing. A puppy quickly learns how to differ praise from reproof by the tone of voice. You must scold a puppy by short sharp words: "Stop!", "Leave!" This method works when the puppy is caught "with the goods". Reproof will at once stimulate the blame.
It is very important to be consistent. First of all, at home. Otherwise a puppy will soon find a "weak spot" among family members and become a burden to him.
