The Old English Bulldog was compact, broad and muscular, as reflected in the well-known depiction Crib and Rosa. Through John Scott's engraving, this painting became the best-known and most reproduced painting of dogs from that period. As described in the Philo-kuon standard from 1865, the average height was approximately, and they weighed about. A particular characteristic of the breed was the lower jaw that projected considerably in front of the upper jaw, which made possible a strong, vise-like grip.
Historians are fairly confident that the Old English Bulldog is derived from ancient war dogs, such as the old Mastiff or the extinct Alauntdog. Others believe that the true origin of the breed is not entirely clear. Depictions in old prints show that the variety was without doubt a small Mastiff with a comparatively long head. The word 'Mastiff' was eventually dropped when describing these smaller Mastiffs, as the Mastiff proper was found too slow for bull-baiting. Eventually, the Greyhound was crossed into the breed, increasing the Mastiff's speed without losing the breed's ferocity. This step reduced the Old English Bulldog's size and weight, with the Greyhound's features seen in specimens of that time.
Description
Two other recognized members of the breed can be seen in the 1817 painting Crib and Rosa, with Rosa exemplifying the form and size of the ideal type of Old English Bulldog, albeit deficient in wrinkles about the head and neck and in substance of bone in the limbs. They are faster than regular bulldogs and have an average speed of. Many authors bring us descriptions about the extinct bulldog, but a description stands out as one of the most extensive by William Hamilton Maxwell: , 1863. Prick ears.
Decline
In England, the passage of the Cruelty to Animals Act 1835 caused a decline of bull-baiting and dog fighting, leading to a lack of interest in perpetuating the Old English Bulldog. Three dogs from the Duke of Hamilton's strain of Old English Bulldog, Wasp, Child, and Billy, were depicted in a painting and recognized as some of the last known members of the breed before they became extinct. Despite the laws making dog fighting illegal, the activity continued for many years. Breeders determined a cross between the Old English Bulldog and Old English Terrier created a superior fighting dog with increased quickness and dexterity. This new breed of dog, called the bull and terrier, was a precursor to the Staffordshire Bull Terrier, English Bull Terrier and American Pit Bull Terrier and accelerated the extinction of the Old English Bulldog.
Reincarnations
Several breeders are attempting to recreate this extinct breed, using known descendants of the Old English Bulldog lineage, with some success. As the breed went extinct long before DNA was recognized and little genetic material has survived, it is unclear how much the modern reincarnations of the breed resemble the original Old English Bulldog, and most of the recreations have purposely introduced differences in the breed compared to the original, most prominently reducing the breed's violent nature. One contemporary recreation of the breed started in the 1970s, using a breeding program developed for cattle at The Ohio State University. The lineage has since split into two, known as the Olde English Bulldogge and the Leavitt Bulldog, the Leavitt Bulldog being a lighter, more athletic dog. These modern day versions, though possessing similar physical abilities, do not have the violent temperament of the Old English Bulldog. The line-breeding was done with a foundation of half Bulldog, and the other half Bullmastiff and American Bulldog and American Pit Bull Terrier.
Often confused with the Old English Bulldog, the Bulldog is noted for its sweet disposition; however, it has maintained little of the speed and agility that were the definitive characteristics of the Old English Bulldog.
