Hooper’s Judge was a mix between an English Bulldog and an English White Terrier which means that this dog started life as an English dog and ended his life as an American one. By the present day standards of the modern Boston Terrier dog breed Hooper’s Judge did not conform to the standard because at 30 pounds he was apparently overweight. He was later bred with a smaller female dog known as Burnett’s Gpy and the resultant litter became the founding stock of the modern Boston Terrier breed.

Hooper’s Judge inherited brindle markings from his bulldog parent and white markings from the respective Terrier half. Ever since then brindle and white has been the staple coloration of the Boston Terrier dog breed.

Somewhere along the line it is believed that the French Bulldog was introduced into the genetic stew of the Boston Terrier and such introduction further reduced the size of this dog breed to its present day limit of 25 pounds.

Some dog historians are of the opinion that the Bull Terrier and even the Boxer played some part in the genetic makeup of the Boston Terrier but alas as is so often the case with canine history this cannot be substantiated.
