Spaniel how to see the pure or impure

How can I tell if a Springer Spaniel is pure or not? First look at the coat color, the coat color is black or liver with white markings, white body with black or liver markings, blue or liver colored fancy hair, white with fawn markings can be. Then look at the neck dorsal line and trunk, the neck length should be moderate, strong, neat, in the raised head slightly arched, the forequarters scapular flat, in the end of the close together. I. The following coat color hybrids and blotches are acceptable: (1) Black or liver with white markings or white body with black or liver markings. (2) Blue or liver colored flowering hairs. (3) Tricolored: black, white or liver-colored, and white with fawn markings, usually found on the eyebrows, cheeks, inside the ears, and under the tail. Any white part of the coat can be a marked spot. Other colors, such as lemon, red or orange will not be accepted. Second, the neck dorsal line and torso neck is moderately long, strong and neat, slightly arched at the elevated head, and meets the sloping shoulder continuously and smoothly. This part of the dorsal line from the shoulder to the tail is strong and slightly sloping. The torso is strong and compact, with short ribs and joints. The chest is deep and level with the elbow, and the prothorax is very well developed. The ribs are long and extend continuously to the middle of the torso, tapering off as they reach the end of the rib cage. The lower line is level with the elbow and has a slight upward curve at the side of the abdomen. The back is straight, robust and horizontal. The loin is short, strong and slightly arched. The rump is elegantly rounded and smoothly joined to the hind legs. The rump is gently inclined toward the base of the tail, which drops naturally along the rump. The tail is horizontal or slightly arched. The tail is tightly clamped, and like the hard dog, the tail forms a proper angle with the dorsal line. Third, the efficient movement of the front legs of the forequarters requires the coordination of the forequarters. The scapulae are flat, tightly integrated at the ends, and smoothly intermingled with the contour lines of the trunk. Measured from the top of the shoulder to the end of the scapula and then to the elbow, the scapula and upper arm are clearly equal in length, forming an angle of approximately 90°; this places the front leg well below the trunk and the elbow just below the top of the scapula. The elbow is very close to the torso. The front legs are straight and meet the feet forming a right angle. The bones are strong, slightly flat, and neither too round nor too heavy. The palmar joints are short, strong and slightly oblique, and do not show weakness. Wolf paws are usually excised. The feet are rounded or slightly oval. The feet are compact, nicely arched, medium sized, thickly padded and with decorative hairs between the toes. Fourth, the hindquarters of the English Springer Spaniel should be firm, strong, powerful and well grown in the hips and thighs for work and dog shows. Its entire hindquarters show strength and drive. The thighs are wide and strong and the knees are strong. For efficient hunting, the angle of the hindquarters bone joints, the fly joints, is never greater or less than the angle of the forequarters bone joints, the fly joints. The fly joint has a little roundness, which is not small or obvious in appearance. The hind metacarpal joint (about 1 / 3 of the distance from the hip joint to the foot) is strong and well boned. In posterior view, the posterior metacarpal joints are parallel. The wolf paws are usually excised. The foot is identical to the forefoot except smaller and more compact.
