Dogs are people's friends. They may be big or small. Dogs may be black, white, grey or orange. They have four legs, dark eyes, sharp teeth. Their ears, noses and tails may be long or short. Dogs can run fast and jump high. They listen to the master and perform his orders. Dogs may be very clever. They work in the police or in the emergency services to save people. Dogs bark loudly and wave their tails when they are happy to see their master. I like dogs.
