When your new puppy first comes into a house, he needs to learn that this is his new space. Put him on a leash and walk him through the whole house. This is a time to show him everything, but also use the leash to limit access to areas you don’t want him getting into such as furniture, closets and the kids’ toy box. You should not say ‘no’. Since the puppy has not learned his name yet, he may start to think that is what you are calling him. Instead, let him know your displeasure by using a low voice to issue a “Yack!” sound, while doing a mild tug on the leash every time he sniffs something he is not supposed to touch. Repeat this action. As he moves away from them, you can pet him, say “good dog”, and continue through the house. The puppy un profollica derstands the growl sound, and knows that it means he needs to stay away from something when you growl as he approaches it. It is important to let him sniff the item for a second before growling, so he recognizes what item it is he is to avoid. Dogs remember things by what they smell like, not what they look like. A new puppy will not pick up words, other than his name, but he will understand the growl means not to touch. Other words puppies will learn are those that relate to things they want. If you say ‘dinner time’ every time you get food for the dog, eventually each time he hears that phrase, he will expect a meal. The best way to teach a dog words, is to make sure you constantly use the same ones, and that they are short and easy to learn.
