For over 12,000 years, dogs have lived with people and helped us in our daily lives. In ancient Egypt, the Pharaohs built statues of dogs and thought they were like gods. Today there are about 400 types of dog of different sizes and shapes.
Dogs have the same five senses as people, but their sense of smell and hearing is much stronger. People train dogs to help and work for us. A dog’s sense of smell is very helpful to the police. Dogs can find people, bombs and dangerous gases.
When a dog starts barking, it's often because they've heard something. A dog's sense of hearing is very good and they can hear things that humans can't.
Dogs can also help blind people and become their 'eyes'. They can lead a blind person to the shops, onto buses, or just help them live a normal life.
For many people, dogs are just good company and make perfect fаmily pets. They can be friendly animals, but are usually expensive to keep and you must have the time to take them for walks. If you look after your dog it can be a really good friend!
