The highely modern Dog

he dog is one of the most popular pets in the world (of course cat lovers will argue for cats). Dogs have long played an important role in the lives of humans. It's thought that dogs have been pets for thousands of years. Dogs are often called Man's Best Friend. This is because dogs help man out in so many ways. Types and Breeds of Dogs There are lots of breeds and types of dogs. Dogs vary in size from very small (just a couple of inches tall) to very large (three feet tall). Some breeds of dogs are considered better for indoor or outdoor pets and some breeds are considered working dogs. Jobs that dogs perform include hunting, police work, rescue work, and seeing-eye dogs for the blind. Because dogs are intelligent and willing to be trained, they make a great companion and work animal.
