Often we hear that a dog is a man's best friend. Indeed, pets, not only dogs have become increasingly common residents of our modern day households. Pets bring to the people a sense of liveliness. That after a day of hard work, people can now relax with a sight of their pets jumping happily around them. Then there is also the sense of responsibility. For those who find raising a child a hassel, raising a pet is no easier, however, knowing that you have provided for another living being is a great feeling. It also teaches the next generation the importance of looking after animals and cherishing all living things here on earth.Clearly, pets not only bring excitement into the world but they also help people develop the important sense of responsibility.
