After reading a book 'Dogs at work'...

'Dogs at work' was written by Robyn O'Sullivan. It is a documentary story about how dogs help the people at work. It says there are so many kinds of dogs. They are good friends to us. Many people have pet dogs at home but some dogs are trained to help people. We can usually call these kinds of dogs 'Working dogs'.

The dogs are classified into some groups. There are guide dogs, service dogs, customs dogs, herding dogs, search and rescue dogs etc. First, guide dogs help people who are visually impared. Many guide dogs are Labrador retrievers. They are suited to guiding their host because they are calm, quiet and intelligent. And secondary, service dogs help people who are unable to do some things for themselves. Most service dogs are golden retrievers or Labradors. Customs dogs work at customs checkpoints with customs officers at airport and seaports. They are generally looking for things such as fruit, vegetable and meat using their sense of smell. Spanish, Labradors and beagles make good customs dogs. Herding dogs work to help farmers to look after their livestock. They can herd livestock into a group and then the dogs move the animals into a new pasture or field. Border collies, sheepdogs, and blue healers can be used. Finally, search and rescue dogs work to find people who are lost or in danger or trapped in wreckage after earthquakes or disasters. The best kinds of dogs for this job are golden retrievers, Labradors, terriers, bloodhounds and German shephered.

These kinds of dogs have something in common. They are very clever and intelligent. They also have very good sense of smell or hearing. I love dogs, too. If you are interested in dogs, this book will be great for you.
