History of American Mastiff

History is replete with tales of powerful guardian dogs, and the Mastiffs have always been central to such narratives. These colossal dogs, known for their formidable presence, have been companions to warriors, royalty, and common folk. 

The North American Mastiff’s tale began in the 1980s when Ohio-based breeder Fredericka Wagner embarked on a mission. Her ambition was to craft a healthier and refined version of the Mastiff. By crossbreeding English Mastiffs with Kangal Shepherds, she aimed to mitigate common health issues and the trait of excessive drooling. 

The birth of the North American Mastiff marked the realization of Wagner’s dream, and the breed quickly rose to prominence.
