Most people have had a dog or wanted one as their companion at some time in their lives. If you are thinking of buying a dog, however, you should first decide what sort of companion you need and whether the dog is likely to be happy in the surroundings you can provide. Specialists' advice is useful to help you choose the most suitable kind of dog. But in part the decision depends on common sense. Different dogs were originally developed to perform. specific tasks. So, if you want a dog to protect you or your house, for example, you should choose the one that has the right size and characteristics. You must also be ready to devote a great deal of time to training the dog when it is young and give it the exercise it needs throughout its life, unless you live in the countryside and can let it run freely. Dogs are demanding pets. Cats love the house and so are satisfactory with their place where there is secure, but a dog is loyal to its master and consequently wants him to show proof of his affection. The best time to buy a baby dog is when it is between 6 and 8 weeks old so that it can transfer its love for its mother to its master. If baby dogs have not established a relationship with the human being until they are over three months old, their strong relationship will always be with dogs. They are likely to be too shy when they are brought out into the world to become good pets.
Which of the following is NOT true according to the passage？
Advertisement can be thought "as the means of making known in order to buy or sell goods or services". Advertisement aims to increase people's awareness and arouse interest. It tries to inform. and to persuade. The media are all used to spread the message. The press offers a fairly cheap method, and magazines are used to reach special sections of the market.

Public notices are fairly cheap and more permanent in their power of attraction. Other ways of increasing consumer interest are through exhibitions and trade fairs as well as direct mail advertisement.
There can be no doubt that the growth in advertisement is one of the most striking features of the western world in this century. Many businesses such as those handling frozen foods, liquor, tobacco and medicines have been built up largely by advertisement.
We might ask whether the cost of advertisement is paid by the producer or by the customer.

However, if large scale advertisement leads to increased demand, production costs are reduced, and the customer pays less.
It is difficult to measure exactly the influence of advertisement on sales. When the market is growing, advertisement helps to increase demand. When the market is shrinking, advertisement may prevent a bigger fall in sales than would occur without its support. What is clear is that businesses would not pay large sums for advertisement if they were not convinced of its value to them.
Advertisement is often used to ______.
