Question: Which breed of dog is larger, Chihuahua or Bernese Mountain Dog?
Context: A draught dog, draft dog, or cart dog is a variety of working dog used to pull a cart.  Dogs have been used to move both people and product, in two separate events; sulky pulling and drafting.  Collies, Bernese Mountain Dogs, St. Bernards, Bouvier des Flanders, Newfoundlands and Rottweilers were all bred for this purpose; Rottweilers and Collies were also used as sheepdogs. The Maremma Sheepdog, in Italian Cane da pastore Maremmano-Abruzzese, is a breed of livestock guardian dog indigenous to central Italy, particularly to Abruzzo and the Maremma region of Tuscany and Lazio.  It has been used for centuries by Italian shepherds to guard sheep from wolves.  The literal English translation of the name is "The dog of the shepherds of the Maremma and Abruzzese region".  The English name of the breed derives from that of the Maremma marshlands, where until recently shepherds, dogs and hundreds of thousands of sheep over-wintered, and where the breed is today abundant although sheep-farming has decreased substantially.  The breed is widely employed in Abruzzo, where sheep herding remains vital to the rural economy and the wolf remains an active and protected predator.  Similar breeds include the Pyrenean Mountain Dog, the Kuvasz of Hungary, the Tatra of Poland, the Cuvac of Slovakia and the Šarplaninac (although not white), with all of which it may share a common ancestor; and the Akbash Dog of Turkey. A grief therapy dog (also known as an emotional support dog, companion dog, or comfort dog) is a form of animal-assisted therapy.  Dogs have been proven to be able to assist people in overcoming grief, which has led to a recent rise in the use of therapy dogs; although animal-assisted therapy theory has been around since World War II.  Grief therapy dogs can be found in locations such as funeral homes, hospitals, nursing homes, schools, and hospices, and may provide support in situations such as funeral services, counseling sessions, and disaster relief.  Popular breeds used as therapy dogs include the Portuguese Water Dog, Bernese Mountain Dog, St. Bernard, and Golden Retriever. The chizer is a mixed dog breed originating in the United States of America.  Chizers are a mix of the Chihuahua and the miniature schnauzer.  This breed is NOT recognized by the American Kennel Club.  The chizer has a combination of looks from both breeds of dogs, and can vary depending upon the breakdown of the breed.  General sizes of a chizer range between 6-14 inches in height and approximately 4-15-lbs in weight.  The chizer is a small breed dog, and works great in smaller areas, such as apartments, condos, and townhomes.  The chizer comes in a typical variety of colours, usually grey, black, brown or white.  This breed has a smooth, short haired coat that needs constant grooming, trimming around the eyes, ears and nose.  They are usually low to average shedding dogs, and typically most groomers leave their facial hair to mimic a schnauzer beard.  The ears of a chizer are medium in length and can stand erect when at attention, and their tail is usually docked.  The chizer can have either an apple shaped head, or round head, with either a long or short snout, giving it either the appearance of a Chihuahua or Miniature Schnauzer.  The body of the chizer is generally long and lean, with slender legs, and a square, robust back end.  This back end tends to make the dog sturdier, and gives them surprising jumping abilities to reach great heights. Malignant histiocytosis (also known as "Histiocytic medullary reticulosis" ) is a rare hereditary disease found in the Bernese Mountain Dog and humans, characterized by histiocytic infiltration of the lungs and lymph nodes.  The liver, spleen, and central nervous system can also be affected.  Histiocytes are a component of the immune system that proliferate abnormally in this disease.  In addition to its importance in veterinary medicine, the condition is also important in human pathology. A Bernedoodle is a crossbreed dog involving a poodle and a Bernese mountain dog.  The crossbreed is known for the hypoallergenic properties of its coat.  They are extremely smart, loyal, and good in nature.  They are considered a designer dog. The Georgian Shepherd (Georgian: ქართული ნაგაზი "qartuli nagazi") is a molosser-type livestock guardian breed of dog with ancient working origins in the Georgia Caucasus.  The Georgian shepherd is related to the Caucasian Shepherd Dog.  There are two kinds of Georgian mountain dog: the short haired Kazbegian dog, also called "Nagazi", and the long haired Georgian mountain dog. The Bernese Mountain Dog (German: "Berner Sennenhund" ) is a large-sized breed of dog, one of the four breeds of Sennenhund-type dogs from the Swiss Alps.  The name "Sennenhund" is derived from the German "Senne" ("alpine pasture") and "Hund" ("dog"), as they accompanied the alpine herders and dairymen called "Senn".  "Berner" (or "Bernese" in English) refers to the area of the breed’s origin, in the canton of Bern.  This mountain dog was originally kept as a general farm dog.  Large Sennenhunde in the past were also used as draft animals, pulling carts.  The breed was officially established in 1907.  In 1937, the American Kennel Club recognized it; today, the club classifies it as a member of the Working Group. The Entlebucher Sennenhund or Entlebucher Mountain Dog is a medium-sized herding dog, it is the smallest of the four Sennenhunds, a dog type that includes four regional breeds.  The name Sennenhund refers to people called "Senn", herders in the Swiss Alps.  Entlebuch is a region in the canton of Lucerne in Switzerland.  The breed is also known in English as the Entelbuch Mountain Dog, Entelbucher Cattle Dog, and similar combinations. The Chihuahua (Spanish: "chihuahueño" ) is the smallest breed of dog and is named after the state of Chihuahua in Mexico.  Chihuahuas come in a wide variety of colors, and two coat lengths.
