Pacing - A symmetrical gait in which the time interval between footfalls on
one side is zero; two right feet on the ground and two left feet in the air
followed by two left feet on the ground and two right feet in the air; a
pace produces a body bowing in the vertical plane, the withers and pelvis move straight ahead and the body in between the withers and pelvis bows to the right and then to the
left; by tradition dogs are not judged at a pace (judged at a trot).
At AKC shows three breeds by their Standard can pace in the show ring. The Old English Sheepdog may amble or pace at slower speeds in the show ring. Polish Lowland Sheepdog is often an ambler. Pacing in the show ring is not to be penalized in the Neapolitan Mastiff.
The Great Pyrenees AKC Standard of 1935 stated: “In the rolling, ambling gait it shows unmistakably the purpose for which it has been bred, the strenuous work of guarding the flocks in all kinds of weather on the steep mountain slopes of the Pyrenees.” The present Great Pyrenees AKC Standard (1990) makes no reference to the rolling, ambling gait.
All breeds, especially long legged breeds, can and usually will pace at some time during their time in the field. It is a relaxation gait or a change of pace gait. It is also a slow
gait that many dogs will use in the show ring as they get up to the show ring trot. Generally this is not noticed as it generally is in the first one or two strides.
