The Vizsla is a natural hunter endowed with a good nose and an above average trainability. Although they are lively, gentle mannered, demonstrably affectionate and sensitive, they are also fearless and possessed of a well-developed protective instinct.(Wikipdeia)
Vizslas are very high energy, gentle-mannered, loyal, caring, and highly affectionate. They quickly form close bonds with their owners, including children. Often they are referred to as "velcro" dogs because of their loyalty and affection. They are quiet dogs, only barking if necessary or provoked.(Wikipedia)
