The dog or domestic dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf. The dog is derived from an ancient, extinct wolf, and the modern wolf is the dog's nearest living relative. The dog was the first species to be domesticated, by hunter-gatherers over 15,000 years ago, before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.
The English Springer is a breed of gun dog in the Spaniel group traditionally used for flushing and retrieving game. It is an affectionate, excitable breed with a typical lifespan of twelve to fourteen years. They are very similar to the Welsh Springer Spaniel and are descended from the Norfolk or Shropshire Spaniels of the mid-19th century; the breed has diverged into separate show and working lines. The breed suffers from average health complaints. The show-bred version of the breed has been linked to "rage syndrome", although the disorder is very rare. It is closely related to the Welsh Springer Spaniel and very closely to the English Cocker Spaniel; less than a century ago, springers and cockers would come from the same litter. The smaller "cockers" hunted woodcock while the larger littermates were used to flush, or "spring", game. In 1902, The Kennel Club recognized the English Springer Spaniel as a distinct breed. They are used as sniffer dogs on a widespread basis. The term Springer comes from the historic hunting role, where the dog would flush (spring) birds into the air. (Full article...)

Jack the Bulldog is the official mascot of the Georgetown UniversityHoyas athletic teams. The school has employed at least eight live Bulldogs as mascots, and counts seven named Jack since 1962, when the name first came into use, including three who are still living. The current incarnation of Jack, who will be taking over from his predecessor during the 2019–20 academic year, is an English Bulldog born in 2019 whose full name is John F. Carroll. Recent bulldogs have come from the Georgetown alumni family of Janice and Marcus Hochstetler.
Jack was not always the name of the Georgetown Hoyas' mascot, nor was the mascot always a bulldog, as other types of dogs, particularly bull terriers, were associated with the sports teams before 1962. In 2009, the American Kennel Club ranked Jack as the 8th most popular dog in American culture. Today, Georgetown is among thirty-nine American universities to use a bulldog as their mascot, with Georgia, Butler, Mississippi State, Yale, and James Madison being the only others with a live bulldog. Jack is also portrayed by a costumed character Bulldog mascot, a tradition dating to 1977. In 2019, a campus editorial called for replacing the bulldog with a rescue dog, in part because of the health problems and short lifespans that many bulldogs face. (Full article...)
