Dogs have been "man's best friend" for as long as we can remember. These loyal companians were originally domesticated to hunt for us. Today, many people keep them as pets. Dogs are intelligent animals and can obey commands when they are given. There are many different breeds that include the Jack Russell Terrier, Pitbull, and Boston Terrier. Although many people own one, there are lots of dogs living in animal shelters that don't have a place to call home. If you are looking for a pet that is friendly, loyal, and smart, then a dog is the right pet for you.
