Dogs are called "man's best friend". Humans and dogs have been together for so long that they have a natural bond with each other. In fact, people and dogs have become so used to each other's behavior that they can even understand one another.
Today, dogs are kept by humans for different reasons. This type of animal is so skilled and useful that they serve people in a lot of ways. There are people who use dogs for hunting, and they can also assist us, working dogs for herding and pulling loads. The government also uses dogs to help them with their work. People with disabilities also find them helpful and inspiring, and of course, pet owners simply adore them as companions and friends (best friends, even).
Since they are our friends there's so much more we need to learn about them such as their behavior and characteristics so we can take care of them better.
More fascinating information and great pictures of dogs are featured in this book especially made for young learners.
