But Pulis do best when not kept as indoor pets in a small living space. Pulis kept indoors need a lot of exercise to use up their energy, or they can became either shy or overactive. They need to get the kind of exercise they were created for. A Puli without enough exercise can became mischievous and cause trouble. The right kind of exercise includes running, biking, hiking, jogging and field work; not just a walk around the corner. Pulis are best kept in a house with a garden.
