Dog are special animals that have earned a place in our hearts and our homes. They have been close companions for people since the earliest times and they still work and play with us today. That's why they are often called "Man's Best Friend". Dogs are clever creatures with strong, athelic bodies. They are alert and plyful and they can move with great speed and agility.
All dogs are mammals. They have warm blood, fur and they feed their babies with milk.
