Temperament: The Polish Owczarek Nizinny is a curious, muscular, agile dog. This is an animated, happy, and alert dog with a good memory. It is a working dog at heart; it once watched over herds and flocks on the Polish plains. It is responsive to firm, fair obedience training; but it is also clever, strong-willed, and likes to think for itself and make its own decisions. This dog learns quickly and is very willing to please; however, it can be willful at times. Socialization at an early age is a must. This breed needs a firm and consistent owner. It has been known to get into mischief if left in the house alone too long. It is excellent with children when raised with them from puppyhood. It can be friendly with other dogs and usually does okay with other non-canine pets. The Polish Owczarek Nizinny is a serious, responsible dog, though it could bite if provoked. It makes an excellent watchdog and guard dog; it has been known to thwart even a bear to protect a child. It may nip at people's heels, displaying herding behavior. As a working dog for many centuries, this dog is happiest when it is given a job to do; it is lively and clever enough to work sheep alone. This breed needs plenty of exercise, playing an active game of catch or Frisbee, or joining agility classes are just some of the things you can do to keep your dog simulated and happy.
