The phrase “A dog is man’s best friend” as made by Frederick II, King of Prussia (1740–1786) can never be overrated. Dogs go beyond providing companionship to providing emotional support and security.  It's no surprise then that many people around the world would opt first for a dog as an additional member of a family, a pet or a friend. While these fluffy creatures exist in homes all over the world, some countries have particularly high numbers of them.
