Heartgirth/Ribs
The back should be strong, compact and level with a slight curve at the withers. The back should not dip or sway. The topline should be gently sloped from the withers to a short, level back and loin and then to a moderately long and sloping croup and well-placed tail.
Rationale:
A good topline adds to balance and general appearance. Backs which are too long or too short look unbalanced, awkward and contribute to poorly coordinated movement.
