History
The Jack Russell Terrier originated in England in the 19th century, thanks to the efforts of the Rev. John Russell. He created a breed of Fox Terrier to meet the need for a dog that ran with his Foxhounds and could flush out fox and other wild animals. Two varieties were developed with fundamentally similar Standards except for some differences concerning mostly height and proportions. The taller, more square-built type is now known as the Parson Russell Terrier, while the shorter, proportionately slightly longer type is known as the Jack Russell Terrier.
Important proportions
The dog as a whole is longer than tall, that is, it is rectangular.
