The Puli is a small-medium breed of Hungarian herding and livestock guarding dog known for its long, corded coat. They need to get the kind of exercise they were created for. They are loyal to their owners and wary of strangers. They are highly active and keep a playful, puppy-like behavior their entire lives. They need a lot of exercise and free space, preferably outdoors. They can be trained and housebroken, but Pulis are generally not very well suited as city or indoor pets. They can be trained and housebroken, but Pulis are generally not very well suited as city or indoor pets. When restricted to closed spaces for long periods of times, they grow restless and may develop unwanted personality traits, such as becoming hyperactive or, instead, increasingly aloof and lazy. As a working dog, the Puli is very obedient, focused and determined when assigned a task. Some of them are used as police dogs.
