You have quite a few options!  Generally speaking, dog breeds are categorized by size.  For example, large dogs include the Saint Bernard, Great Dane, and Akita Inu.  Small dogs include Chihuahuas, Toy Poodles, and Maltese Terriers.  Then there are the giant dogs, like the Great Dane, which stand 24-28 inches tall at the shoulder and weigh from 110 to 225 pounds.  Medium-sized dogs include beagles, which stand 16-20 inches tall at the shoulder and weigh from 30 to 65 pounds.
