This hybrid combines the gentle temperament of both parent breeds with impressive physical attributes, typically standing between 30-34 inches at the shoulder. While their imposing size may seem intimidating, Daniffs are renowned for their gentle, affectionate nature and loyalty to their families. These dogs, which can live up to 12 years, require considerable space, consistent training, and proper healthcare, making them better suited for experienced dog owners.
