The term "small breed" refers to a type or category of dog that is generally considered smaller in size compared to other types of dogs. These dogs typically weigh less than 20 pounds and have compact bodies with short legs, making them ideal for living in small spaces such as apartments or condominiums. Some popular examples of small breeds include Chihuahuas, Pomeranians, Yorkshire Terriers, and Maltese dogs. These dogs are often chosen because they require less space to live and exercise, and can be easily transported when needed.
