There are many species of animals that share a bonding with we humans. Amongst all, our most loyal friend has always been the Dog. Humans and dogs have been inseparable for thousands of years depending on each other for protection and survival. From earlier days we have relied on dogs for hunting and guarding and now more as pets for companionship, protection and their showmanship.
Dogs belong to the family Canidae which includes wolves, jackals and foxes. All modern domestic dogs (Canis familiaris) have descended from the grey wolf. They have lived with humans for over 10,000 years. By 6,000 years ago, dogs had been bred with the looks, sizes, and abilities we still see today.
In all the regions of northern hemisphere, people formed constructive relationships with dogs, and generations of selective breeding resulted in dogs becoming specialized in their abilities to work for and with humans. By the end of 19th century, over 400 breeds of dogs were recognized by kennel clubs around the world. Virtually all of these breeds exist today, but the dog’s role is still evolving. Today, most of the dogs are bred for companionship.
