What are the dog breeds

There are hundreds of dog breeds around the world, and common breeds are distinguished by large and small dogs: small dogs such as the Poodle, Pomeranian, Yorkshire and Bichon Frise are smart and well-behaved puppies. Common medium-sized dogs include Golden Retrievers, Labradors, Corgis and other well-trained dogs. Large dogs such as St Bernard and Alaskan are usually more difficult to care for and are kept by fewer people.
