Dog Quiz – Our Oldest Animal Friends

Dogs have lived alongside humans for at least 15,000 years, longer than any other domestic animal. They began as wolves that stayed near human camps and slowly became partners in hunting, herding and guarding. Today there are hundreds of millions of dogs worldwide, and many families think of them as part of the household.

Over centuries, people bred dogs for different jobs, creating an amazing variety of shapes and sizes. Dachshunds were bred to chase badgers, retrievers to fetch birds, sheepdogs to manage flocks and tiny breeds like the Chihuahua mostly as companions. Breeds range from Great Danes taller than a person on their hind legs to dogs small enough to sit in a handbag.

Dogs also have remarkable senses. Their noses can pick up scents in amounts far too small for humans to notice, which is why they work as search-and-rescue dogs, sniffer dogs at airports and even medical detection dogs. Their hearing is sharper too, picking up high-pitched sounds people cannot hear.

History is full of famous dogs. Laika became the first animal to orbit Earth, Balto helped carry medicine to Nome, Alaska, in 1925, and Hachikō's loyalty made him a national symbol in Japan. Guide dogs, therapy dogs and police dogs continue to help people every day.

This quiz covers dog breeds, senses, history and famous dogs.

Caring for a dog is a big commitment. Different breeds need very different amounts of exercise, grooming and training, so experts recommend researching before choosing a puppy or adopting from a shelter. Mixed-breed dogs from rescue centers often make loyal and healthy companions.
