What structural relationship results in the Wire Fox Terrier's required square appearance regarding body dimensions?

Answer

The length of the body from the point of the shoulder to the point of the buttock should be roughly equal to the height from the withers to the ground

The breed standard for the Wire Fox Terrier emphasizes a balanced, symmetrical structure, often referred to as square. This 'squareness' is a precise measurement requirement where the overall length of the body, measured from the point of the shoulder back to the point of the buttock, must approximate the dog's standing height measured from the ground up to the withers. This configuration ensures the dog has a compact yet balanced frame, preventing it from being overly long-backed, which supports endurance and agility during sustained work.
