Source:Enciclopedia del perro Royal CaninThe aplomb is the address of the members with respect to a horizontal floor. The Aplomb have a marked influence on the dorsal line and consequently on the dog's overall contribution well as their potential for sports. Determine a good support, like a good distribution of weight on their articulations and feet. In general, for a correct aplomb of a member, its principal axis must be vertical. A deviation with respect to the vertical is a stress on joints and the plantar surface (on the side of the deviation) and therefore one fatigue premature of these articulations, tendons and ligaments different.
When a dog is planted, the dorso-lumbar line sinks or overwhelms, and back then takes an oblique position. If their previous members are also sunk, reportedly saddled. In a 'put back' dog, the back is curved upward. The condition of 'knock kness'[sketch like -> ')(' ] is frequent in the rear limbs, since it is a natural tendency. On the contrary, the condition of arched or bowlegged [sketch like -> '()' ] is a more serious defect.
Aplomb in Past members
Side view or profile: Vertical descending from the point half of the arm passes through the middle of the foot and is tangential to the wrist (front face of the Carpus). If it falls before the midpoint of the foot, the dog is under him or if it falls behind is planted. If the Carpus is behind this line, the dog is told trascorvo, while if it is ahead, it is arched and the animal is short arm. If this vertical falls away from the pads, the dog is long pastern, while if the touch it, told stood of pastern.
Arched in o bowlegged [sketch like -> '()' ] : The carpus and elbows are angled outward, reeds and feet inward.
Bowed out, left o 'knock kness'[sketch like -> ')(' ]: The elbows are close to the body, while the feet are reeds and out. Deviations that characterize to the aplomb bowlegged [sketch like -> '()' ] y 'knock kness'[sketch like -> ')(' ] can start at any level of the limb.
Closed or open front: The forelegs are oblique and converge or diverge towards their ends. Not to be confused with narrow or wide, a situation in which both members are parallel but they are somewhat or very separated. If only the wrists are in, we talk about knees locked, whereas if it are curved outward the line of aplomb is said that the dog is hollow. Limbs are said are lyre-shaped when presenting a convexity outwards.
Rear limb aplomb
Side view or profile: The cane must be perpendicular to the ground and vertical falling from the articulation should pass through the middle of the foot.
Rear view: The vertical line passing through the point of the buttock and the hock cane divides equally. The dog may be too closed or too open, which is determined by the convergence or divergence of the two members in their limbs. Do not confuse these conditions with the dogs too narrow or too wide.
When the Member suffers a rotation to the outside from the hip joint, gets a limb 'knock kness'[sketch like -> ')(' ] or left. This is accompanied by knees and divergent feet, while the tips of the hocks converge. If the rotation is inward, it's a hole in, bowlegged [sketch like -> '()' ] rear or hollow of hocks. Knees and feet ends converge, while the tips of the hocks devergen.
