[speaker001:] I was just watching a documentary on TV about how people use dogs for various purpose. It was very interesting.
[speaker002:] I love dogs. They have been used as guards for centuries. Nowadays, they are often used to find illegal drugs and bombs by the police and customs officers.
[speaker001:] The documentary also pointed out that they are used by shepherds to round up sheep and by rescue workers to find people trapped under rubble or snow.
[speaker002:] Horses are useful to people too. We use them for sports and recreation.
[speaker001:] Don 't forget that horses are still used in many countries to pull ploughs and carts.
[speaker002:] Can you ride a horse?
[speaker001:] Yes, I can. I don 't ride regularly though. How about you?
[speaker002:] I can ride too. Perhaps we could go horse riding together at the weekend?
[speaker001:] What a good idea!
