Meet Sentinel & Soul Kennels

Welcome to Sentinel & Soul Kennels, where power, presence, and purpose meet. We are dedicated breeders of the magnificent North American Mastiff, producing dogs that embody the ultimate balance of a vigilant guardian and a devoted family companion. Our Foundation & Breed Heritage: The North American Mastiff is a prestigious, newer breed meticulously created and curated right here in the United States. Originally known in its developmental stages as the “Deboar X,” visionaries of this breed strategically selected and crossed elite dogs from distinct, world-renowned mastiff lineages to forge a superior guardian. The North American Mastiff is a composite breed built from the finest traits of: 🔹South African Mastiff (Boerboel) 🔹French Mastiff (Dogue de Bordeaux) 🔹Italian Mastiff (Cane Corso) 🔹Neapolitan Mastiff (Mastino Napoletano) 🔹Alapaha Blue Blood Bulldog ( strictly distinguished from XL, Pit, or other generic bull breeds) Commitment to Health & Excellence At Sentinel & Soul Kennels, we believe that true quality starts from within. To ensure our dogs are as healthy as they are striking, we rigorously test all of our breeding adults and puppy productions through Embark. This comprehensive screening covers critical Breed Characteristics, Health Predispositions, and Genetic Traits, giving you total confidence in your new family protector. The North American Mastiff Standard 🔸Appearance: These are awe-inspiring, very large dogs typically ranging from 130 to 200+ lbs. They feature a massive, blocky head with a powerful jaw, resting on a broad chest, thick-boned structure, and a profoundly muscular frame. Their short, dense coats can appear in various stunning shades including brindle, fawn, black, blue, and striking patterns like black merle. While naturally drop-shaped, ears are often proudly cropped to complete their signature guardian silhouette. 🔸 Temperament: A true gentle giant. While they possess an innate, watchful protectiveness as natural guardians fiercely loyal to their families, they are famously calm, affectionate, and wonderful with children when properly socialized. They are confident and stable—standing their ground with quiet authority rather than unpredictable aggression. 🔸 Lifestyle & Care: They require moderate exercise—steady daily walks and playtime satisfy their needs without the relentless energy of herding breeds. While they thrive with space like a yard or land, many adapt wonderfully to home life with proper routine. Given their immense size and power, early socialization and consistent training are pillars of our philosophy. At Sentinel & Soul Kennels, we don’t just breed North American Mastiffs; we honor their legacy, protect their future, and match their incredible souls with homes that demand the absolute best.
