Pet Exhibition in Expo Karachi

Today i am going to expo for pets exhibition.because i love pets and my favorite pet is Dog because Dogs are friendly for humans.
a pet is kept to entertain people or for companionship. Some pets such as dogs and cats are placed in an animal shelter if there is no one willing to take care of it.Dogs are domesticated mammals, not natural wild animals.
1)DOG's:-
Today, some dogs are used as pets, others are used to help humans do their work. They are a popular pet because they are usually playful, friendly, loyal and listen to humans. Thirty million dogs in the United States are registered as pets.[4] Dogs eat both meat and vegetables, often mixed together and sold in stores as dog food. Dogs often have jobs, including as police dogs, army dogs, assistance dogs, fire dogs, messenger dogs, hunting dogs, herding dogs, or rescue dogs.
2) Appearance and behaviour:-
Dogs can smell and hear better than humans, but cannot see well in color because they are color blind. Due to the anatomy of the eye, dogs can see better in dim light than humans. They also have a wider field of vision.
3)Lifespan;-
Different dog breeds have different lifespans. In general, smaller dogs live longer than bigger ones.[5] The size and the breed of the dog change how long the dog lives, on average. Breeds such as the Dachshund usually live for fifteen years.
4)Dogs and humans
Dogs are often called "man's best friend" because they fit in with human life. Man refers to humankind and not just guys (Old English). Dogs can serve people in many ways. For example, there are guard dogs, hunting dogs, herding dogs, guide dogs for blind people, and police dogs. There are also dogs that are trained to smell for diseases in the human body or to find bombs or illegal drugs
