The Polish Lowland Sheepdog is a dog of medium size, compact, strong, muscular, with a thick long coat. Their well groomed coat gives an attractive and interesting appearance. The proportion of height at withers to length of body is 9:10. The ratio length of muzzle to length of skull is 1:1; however a muzzle slightly shorter than this is acceptable. It has a lively but tempered disposition and is vigilant, agile, intelligent, perceptive and gifted with a good memory. The PON is resistant to unfavourable climatic conditions.
Dogs are 45-50cm; bitches: 42-47cm. The PON must retain the type of a working dog, therefore their size must not go down below the standard. They must be neither weak nor delicate.
The head is of medium dimension, proportional and not too heavy. The thick fur on the forehead, the cheeks and the chin give the head a look of being bigger than it actually is. The skull is not excessively broad and slightly rounded. The frontal furrow and occipital protuberance are noticeable, the stop is well accentuated and the nose is as dark as possible in relation to the colour of the coat, with large nostrils.
The muzzle is strong and blunt, with a straight nasal bridge. The lips fit well; their edges are of the same colour as the nose. The jaws and teeth are strong, with a scissor or level bite accepted. The eyes are medium size, oval, not protruding, hazel in colour, with lively and piercing look. The rims of the eyelids are dark. The ears are hanging, set not too high, of medium size, heart-shaped and wide at the base; the fore edge is close against the cheeks and mobile.
The neck is of medium length, strong, muscular, without dewlap, carried rather horizontally. The body is rectangular in outline rather than square, the withers are well accentuated. The back is flat and well muscled; the loin is broad and well fused; the croup is short and slightly truncated. The chest is deep, of medium width, ribs quite well sprung, neither flat nor barrel-shaped. The underline and belly curve towards the hindquarters.
Tail: naturally short, stumpy, tailless, very shortly docked tail. The undocked tail is quite long and very hairy. At rest the tail is hanging; if the dog is alert the tail is gaily curved over the back, never curled or lying on the back. Naturally undocked tail of medium length, carried in different manners.
The Forequarters when seen in profile and from the front are vertical and straight. Stance is well balanced due to a strong skeleton (bone structure). The shoulders are broad, of medium length, oblique, clean cut, very muscular. Pasterns are slightly slanting in relation to the forearm. The forefeet are oval, tight, slightly arched toes with hard pads. Nails short and preferably dark.
Hindquarters when seen from behind are vertical and well angulated. The thighs are broad and muscular. Hocks are well accentuated. The hind feet are compact and oval shaped. Movement is easy and ground covering with a smooth walk or trot smooth, often pacing.
