Here is the description from wikipedia:
The Komondor (lat. Canis familiaris pastorialis villosus hungaricus) is a livestock guardian dog breed originally from Hungary. The plural is in Hungarian “Komondorok”[
Its long, thick, strikingly corded white coat (the heaviest amount of fur in the canine world) resembles dreadlocks or a mop. The puppy coat is soft and fluffy. However, the coat is wavy and tends to curl as the puppy matures. A fully mature coat is formed naturally from the soft undercoat and the coarser outer coat combining to form tassels, or cords. Some help is needed in separating the cords so the dog does not turn into one large matted mess. The length of the cords increases with time as the coat grows. Shedding is very minimal with this breed, contrary to what one might think (once cords are fully formed). The only substantial shedding occurs as a puppy before the dreadlocks fully form. The Komondor is born with only a white coat, unlike the similar-looking Puli, which is usually white, black or sometimes grayish. However, a working Komondor’s coat may be discolored by the elements, and may appear off-white if not washed regularly. Traditionally the coat protected the Komondor from the wolf’s bite. The wolf wasn’t able to bite the dog through the thick coat.
The Komondor’s temperament is like that of most livestock guarding dogs; it is calm and steady when things are normal. In cases of trouble, the dog will fearlessly defend its charges. It was bred to think and act independently and make decisions on his own. It is extremely affectionate with its family and friends and gentle with the children of the family. Although wary of strangers, it will nonetheless accept them when it is clear that no harm is meant. It is very protective of its family, home and possessions. It will instinctively guard them. The breed has a natural guardian instinct. An athletic dog, the Komondor is fast and powerful and will leap at a predator to drive it off or knock it down. It can be used successfully to guard sheep against wolves or bears. An explosion in the coyote population and a reluctance to use poison baits has led to a renaissance in the use of the Komondor as a flock guardian in the United States.
