Context paragraphs:
Halls Heeler: The Halls Heeler was a dog bred by Thomas Simpson Hall to herd cattle on the Hall family's extensive properties in north-western New South Wales in the 19th century.  On "Dartbrook Station", in the Upper Hunter Valley, Hall selectively crossed the offspring of Northumberland Drover's Dogs (Border Collie lineage) that he had imported, with progeny of dingoes that he had tamed.  By 1840 he had bred the type of dog that he needed to control cattle on the massive runs that his family owned, and until he died in 1870 few of these dogs were owned and used by anyone outside the Hall family and their workers.  However the death of Thomas Hall and the break-up of the Hall estate coincided with the development of the dog show, and an interest in breeding dogs to specific criteria or standards.  The Halls Heeler was further developed into two contemporary dog breeds the Australian Cattle Dog and the Australian Stumpy Tail Cattle Dog.  The name is spelled both with the possessive apostrophe, as Hall's Heeler, and without.

Tech XIX is currently in the care of Tech Alumnus and mechanical engineering professor Dr. Mark Barker.

Olde English Bulldogge: The Olde English Bulldogge is a recently created American dog breed.  In the 1970s David Leavitt created a true-breeding lineage as a re-creation of the healthier working bulldog from early nineteenth century England.  Using a breeding scheme developed for cattle, Leavitt crossed English bulldogs, American Bulldogs, American Pit Bull Terriers and Bull Mastiffs.  The result was an athletic breed that looks similar to the bulldogs of 1820 but also has a friendly temperament.

Uga (mascot): Uga ( ) is the official live mascot of the University of Georgia Bulldogs.  Since 1956, all the dogs serving as Uga have been part of a lineage of English Bulldogs owned by Sonny Seiler.

Leavitt Bulldog: The Leavitt Bulldog is a late 20th-century re-creation of the now extinct Old English Bulldog, the original bulldog breed which existed around the 19th century Regency era, about 1820.  In contrast to English bulldogs of modern times, depictions of the breed from nearly two centuries earlier showed healthier, more agile dogs, with working ability.  Unlike the 19th century breed however, the Leavitt Bulldog has a placid temperament.  It is one of several breeds developed in order to overcome the genetic problems in the English Bulldog breed.  The Leavitt Bulldog was developed by breeder David Leavitt which he originally named the Olde English Bulldogge.  Leavitt has since disassociated himself with this name for the breed and set up the Leavitt Bulldog as its name due to many later OEB litters losing many of the qualities of his original OEB litter.  David Leavitt's "Leavitt Bulldogs" were purebred from the earlier Olde English Bulldogge stock.  Regardless of this, the original name has been adopted by the United Kennel Club whose breed standard is adopted as of 1 January 2014.  The Leavitt Bulldog was mentioned in the documentary "Pedigree Dogs Exposed – Three Years On" as a suggested healthier alternative to the English Bulldog.
