The Polish Owczarek Nizinny (PON) is a very agile and active dog. It prefers households where it can be in the midst of all the activities and even take part in them. This comes from its long history of helping humans in their shepherding activities where it played a key role of guiding the sheep away from danger and moving the flock along. For a PON to be happy, it has to have a regular schedule of activity, fun, and play at all times.

The first routine that should be established in any dog's activity schedule is the daily walks or runs. This dog prefers to run and it likes to do this twice a day. It won't just run if you stick it outside. Left alone, the dog will simply end up in mischief. You have to be there during the exercise sessions to make sure the dog is focused and being engaged actively.

Other types of outdoor activities that these dogs love are playing Frisbee, fetch, and even running doggie obstacle courses. The dog does love water and will take to swimming, if you have an outdoor pool. You can add toys to your play dates that amuse and stimulate the dog's natural curiosity.

A Polish Owczarek Nizinny is a very intelligent dog, but it can also be very stubborn. Don’t expect it to take naturally to a leash without some firm and consistent obedience training. It may do well at times, when it feels like pleasing its owner, but without obedience training the moment it is bored or petulant it will ignore your commands. Obedience training is another activity that you can use as a form of structured play for your PON. It may even get to like the activity as it begins to be rewarding for pleasing behavior. This dog really does live to please its owner but will be petulant, if it thinks it isn't being treated fairly.

These dogs love horsing around with small children and even other mid-sized household pets. They may chase or nip the heels of the kids as they naturally fall into herding behavior at times. This is where obedience training can come in to help adjust some of this herding tendency. The works best when it is always included in the family's activities and has some role, like watchdog, or child companion to play.

Even though the dog will play with children and other small pets, it doesn't like other dogs of the same sex. It is a very dominant dog and will tend to feel threatened by any other alpha dog. Also, if it hasn't been properly socialized early, it shouldn't be left with smaller creatures that it might consider prey instead of flock.
