听力原文：A(man): Hi, Mice. I hear that you are planning to have a dog in your house. Is that true？
B(woman): Yeah. But I am not so sure now. I'd love to have one because I think dogs are good companions.
A: Sure. I think most people have had a dog or wanted one as their companion at some time in their byes. If you are thinking of buying a dog, 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.
B: So. What's you advice？
A: Specialist advice is available to help you choose the most suitable breed of dog. But in part, the decision depends on common sense. Most breeds were originally developed to perform. specific tasks. So, if you want a dog to protect you or your house, for example, you should choose a breed that has the right size and characteristics.
B: I have not decided yet, you know. I just thought dogs are lovely and they will do things you want them to do.
A: That's half true. You must be ready to devote a good deal of time to train the dog when it is young and give it the exercise it needs throughout its life. Dogs are demanding pets. The best time to buy a baby-dog is when it is between 6 and 8 weeks old so that it can transfer its affection from 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.
B: Thank you so much for bring such valuable advice, Tom. I think I am readier than before to have my own dog now.
