Question: Which breed is larger, Rough Collie or Boston Terrier?

full_context: Document 1: Collie: The collie is a distinctive type of herding dog, including many related landraces and standardised breeds. The type originated in Scotland and Northern England. The collie is a medium-sized, fairly lightly built dog, with a pointed snout. Many types have a distinctive white pattern over the shoulders. Collies are very active and agile, and most types of collies have a very strong herding instinct. Collie breeds have spread through many parts of the world (especially Australia and North America) and have diversified into many varieties, sometimes with mixture from other dog types. Some collie breeds have remained as working dogs, used for herding cattle, sheep and other livestock, while others are kept as pets, show dogs or for dog sports, in which they display great agility, stamina and trainability. While the AKC has a breed they call "Collie", in fact collie dogs are a distinctive type of herding dog including many related landraces and formal breeds. There are usually major distinctions between show dogs and those bred for herding trials or dog sports. They typically display great agility, stamina and trainability and more importantly sagacity.
Document 2: Scotch Collie: The Scotch Collie is a landrace breed of dog which originated from the highland regions of Scotland. The breed consisted of both the long-haired (now known as Rough) Collie and the short-haired (now known as Smooth) Collie. It is generally believed to have descended from a variety of ancient herding dogs, some dating back to the Roman occupation, which may have included Roman Cattle Dogs, Native Celtic Dogs and Viking Herding Spitzes. Other ancestors include the Gordon and Irish Setters.
Document 3: Smooth Collie: The Smooth Collie is a breed of dog developed originally for herding. It is a short-coated version of the Rough Collie of Lassie fame. Some breed organisations consider the smooth-coat and rough-coat dogs to be variations of the same breed.
Document 4: Bearded Collie: The Bearded Collie, or Beardie, is a herding breed of dog once used primarily by Scottish shepherds, but now mostly a popular family companion.
Document 5: Shetland Sheepdog: The Shetland Sheepdog, also known as the Sheltie, is a breed of herding dog. The original name of this breed was Shetland Collie, but this caused controversy among the Rough Collie breeders at the time, so the breed's name was formally changed to Shetland Sheepdog. This small dog is intelligent, vocal, excitable, energetic and willing to please and work hard. The breed was formally recognized by The Kennel Club in 1909.
Document 6: Miniature Schnauzer: The Miniature Schnauzer is a breed of small dog of the Schnauzer type that originated in Germany in the mid-to-late 19th century. Miniature Schnauzers developed from crosses between the Standard Schnauzer and one or more smaller breeds such as the Poodle and Affenpinscher, as farmers bred a small dog that was an efficient ratting dog. They are described as "spunky" but aloof dogs, with good guarding tendencies without some guard dogs' predisposition to bite. Miniature Schnauzers are recognized in three colors internationally: solid black, black and silver, and a color known as 'salt and pepper'. There is a controversial fourth color variant in Miniature Schnauzers, pure white, which is not recognized universally.
Document 7: Rough Collie: The Rough Collie (also known as the Long-Haired Collie) is a long-coated breed of medium to large size dog that in its original form was a type of collie used and bred for herding in Scotland. Originating in the 1800s, it is now well known through the works of author Albert Payson Terhune, and through the "Lassie" novel, movies, and television shows. There is also a smooth-coated variety; some breed organisations, including both the American and the Canadian Kennel Clubs, consider the smooth-coat and rough-coat dogs to be variations of the same breed. Rough Collies generally come in shades of sable, merles, and tri-coloured. This breed resembles a bigger version of the Shetland Sheepdog.
Document 8: Teddy Roosevelt Terrier: The Teddy Roosevelt Terrier is a small to medium-sized American hunting terrier. Lower-set with shorter legs, more muscular, and heavier bone density than its cousin the American Rat Terrier. There is much diversity in the history of the Teddy Roosevelt Terrier breed and it shares a common early history with the American Rat Terrier, Fox Paulistinha and Tenterfield Terrier. It is said the Rat Terrier background stems from the terriers or other dogs that were brought over by early English and other working class immigrants. Since the breed was a farm, hunting and utility dog there was little to no planned breeding other than breeding dogs with agreeable traits to each other in order to produce the desired work ethic in the dog. It is assumed that the Feist (dog), Bull Terrier, Smooth Fox Terrier, Manchester Terrier, Whippet, Italian Greyhound, the now extinct English White Terrier, Turnspit dog and or Wry Legged Terrier all share in the Teddy Roosevelt Terrier's ancestry. These early Ratting Terriers were then most likely bred to the Beagle or Beagle cross bred dogs (for increased scenting ability) and other dogs. Maximizing the influences from these various breeds provides the modern Teddy Roosevelt Terrier with a keen sense of awareness and prey drive, an acute sense of smell and a very high intellect. Although they tend to be aloof with strangers they are devoted companion dogs with a strong desire to please and be near their owners side at all times.
Document 9: Lassie: Lassie is a fictional character created by Eric Knight; she is a female Rough Collie dog, and is featured in a short story that was later expanded to a full-length novel called "Lassie Come-Home". Knight's portrayal of Lassie bears some features in common with another fictional female collie of the same name, and is featured in the British writer Elizabeth Gaskell's 1859 short story called "The Half Brothers." In "The Half Brothers", Lassie is loved only by her young master and guides the adults back to where two boys are lost in a snowstorm.
Document 10: Cavalier King Charles Spaniel: The Cavalier King Charles Spaniel is a small spaniel classed as a toy dog by The Kennel Club and the American Kennel Club. It originated in the United Kingdom and is one of the more popular breeds in many countries. Since 2000, it has grown in popularity in the United States and ranks as the 18th most popular pure-breed in the United States (2013 Registration Statistics). It has a silky, smooth coat and commonly a smooth undocked tail. The breed standard recognizes four colours: Blenheim (chestnut and white), Tricolor (black/white/tan), Black and Tan, and Ruby. The breed is generally friendly, affectionate and good with both children and other animals; however, they require a lot of human interaction. Since they are a family dog, it is recommended to not leave them alone for long periods at a time. The expected average lifespan of a Cavalier King Charles Spaniel is under ten years.
Document 11: Boston Terrier: The Boston Terrier is a breed of dog originating in the United States. This "American Gentleman" was accepted in 1893 by the American Kennel Club as a non-sporting breed.

Bostons are small and compact with a short tail and erect ears. The AKC says they are highly intelligent and very easily trained. They are friendly and can be stubborn at times. The average life span of a Boston is around 11 to 13 years, though some can live well into their teens.

This breed is a medium-sized, short-coated dog that occurs in two main colour forms.

It should not be confused with the Australian Shepherd, a similarly named but totally different breed.

It is one of several breeds commonly known as pit bulls. In the early part of the twentieth century the breed gained social stature and was accepted by the American Kennel Club in 1936.
