The Kuvasz is a giant dog, slightly longer than tall, and medium-boned. It is not bulky, but instead light-footed, with a free, easy gait. The breed’s combination of power and agility stems from its versatile roots as a guardian, hunter and herder. Its double coat is medium-coarse, ranging from wavy to straight.

Despite its sweet looks, the kuvasz is a tough protector, fearlessly defending its family or home. It is gentle with and protective of children in its own family, but it may misinterpret a child’s rough-and-tumble games with other children as attacks on its child. It is reserved with strangers and may be aggressive toward strange dogs; however, it tends to be very gentle with other pets and livestock. It is devoted and loyal but not very demonstrative. Some can be domineering.
