These animals can form very close bond with their human owners and in fact dogs are even known as men's best friend. Dog owners would tell you how their best friend would snuggle up close to them for comfort and follow them everywhere and know well their routines such as feeding time and the time when their owners return from work. Experts say that pets are very therapeutic and can even prolong the lives of human being, especially elderly folk or these widowed and living alone. Even young children and the recluse respond well to animals rather than their human companions.
