Pets are often an important part of peoples lives. Different types of animals can be pets, ranging from reptiles to horses. One of the most common pets is a dog. In fact, dogs serve a variety of purposes for humankind. One way dogs serve humans is they are great just for companionship. Many an only child has bonded with his/her “Fido,” thus having a willing and loyal friend to play with on a daily basis.
Additionally, dogs have served humans as work animals, corralling sheep, conquering rats, and guarding the homestead. Finally, dogs are also used to serve the disabled, for example, by leading the blind, alerting the hearing impaired, and alerting epileptics of impending seizures.
