Judges are looking for:
an intelligent head – not too narrow nor too wide – best displayed when concentrating on a biscuit!
a sloping shoulder with adequate length of neck
a well muscled top line along the spine
a straight stern (tail)
straight elbows and hips down to straight feet (no pigeon toes)
a deep chest for lung and heart room
good springy pads and even toenails (seen easily on the flags)
