The PON is a muscular, thick-coated dog. The double coat can be of any color or pattern; white, gray, and brown are most common, with black, gray, or brown markings. It is common for colors to fade as the dogs reach adulthood. The undercoat is soft and dense, while the topcoat is rough and either straight or wavy, but not curly. The hair around the head makes the head appear to be larger than it actually is, and typically covers the eyes.
Males are 45 - 50 cm (18 - 20 inches) in height at the withers, while females are 42 - 47 cm (17 - 19 inches). The body is not square, but rectangular; the ratio of the height to the body length should be 9:10 (a 45 cm tall dog should have a body 50 cm long). The tail is either very short or docked. Some undocked dogs have tails that curl over the back.
Temperament
Polish lowland sheepdogs are stable and self-confident, but are wary of strangers. They have an excellent memory and can be well trained, but may dominate a weak-willed owner. PONs adapt well to various conditions, and are popular as companion dogs for apartment dwellers in their native Poland. PONs require a moderate amount of exercise daily.
