Do you like movies based on dogs? I love such films. Dogs have proven themselves to be stars. They charmed the audience as Marley of John Grogan's 'Marley and me' and 'Benji'. The sledge dogs of 'eight below' warms viewers' hearts and 'Cujo' frightens even the bravest. Even a three headed dog named Fluffy was shown in 'Harry Potter and the Philosopher's Stone'. And who can forget the cute and cuddly spotted puppies of 'One Hundred and One Dalmatians' while 'Peter Pan' even showcased Nana, a dog who acted as a nanny to the children.

History of the human kind is shared by the history of man's best friend, dogs. In today's world it is estimated that there are about 400 million domestic dogs. With the intentional breeding of dogs, the dogs are now divided into hundreds of distinct breeds. Be a poodle, a dachshund, a retriever, a collie, a spaniel or a pit bull, dogs are the most favored breed of pets all over the world.

A dog is said to be the most loyal companion a human can ask for. Trained dogs are even employed by police and army. But my vote is in support of a service dog as the leader of the pack. A service dog or an assistance dog is trained to help people with a disability. They are trained to guide visually handicapped, alert individuals with impaired hearing, and even do rescue work. What more can you ask from a 'best friend'?
