And then, of course, there are countless stories of dogs trained to aid blind, deaf, or wheel-chair bound individuals, often allowing them to live independently when otherwise this would not be possible.

Jeams Herriot, a country veterinarian in England, has been a very popular writer in the English-speaking world. He has written a number of books and stories about pet owners and their pets. Many of his stories tell of the love between them as well as the benefits that owners and pets derive from each other. Part of his great popularity as a writer comes from the fact that people who love pets like to read about and identify with other pet lovers.
