Newfberger Mastin

The Newfberger Mastin is a massive, affectionate guardian with the Newfoundland’s famously gentle, people-focused nature and the Leonberger/Bullkees Mastin line’s alert confidence. Typically calm and steady indoors, this hybrid is happiest when close to family, enjoying moderate daily exercise, consistent training, and a job that lets it watch over the home with quiet devotion.
