Size--Dogs, 25 to 27 inches at the
withers, and 110 to 130 pounds weight. Bitches, 24 to 26 inches at
the withers, and 100 to 120 pounds weight. Other things being equal, the
more substantial dog within these limits is favored.

Expression--Keen, alert, and

When viewed from the side, reach and drive indicate maximum use of the
dog's moderate angulation. Back remains level and firm. Coming and going,

at the joints.

docile. The dog combines the reliability, intelligence, and willingness to
please required in a dependable family companion and
