English Mastiff Breeders, Bloodlines & The Pack Behind Our Puppies
From a Single English Mastiff Dog Dad, to a Dream Fulfilled
I fell in love with the breed the day I got my first English Mastiff, Conan. From that moment on, I knew I wanted to share the unmatched loyalty, warmth, and companionship these dogs bring into your life. It was that first bond which sparked a lifelong dream to breed English Mastiff puppies with the same heart and heritage as my boy, Conan.
Years later, that vision took shape on a 10-acre farm in Sneads, Florida. MLJ Mastiffs was born not from business, but from deep admiration. Today, we raise every pup with the same heart and intention that started it all—with family in mind.

Meet the Sires & Dams
Champion Roots. Gentle Souls
Selecting the right sire and dam is crucial in breeding English Mastiffs that exemplify the breed’s best qualities. At MLJ Mastiffs, we adhere to stringent criteria when hand-selecting our breeding pairs for ideal characteristics in temperament, physique, and lineage. But, our sires and dams are selected for more than just great looks and winning personality. Each is evaluated carefully to ensure they represent the best of the English Mastiff breed—inside and out. This involves a comprehensive evaluation of several key factors:
- Comprehensive Health & Genetic Screening
All breeding dogs undergo OFA testing for hips, elbows, and heart, along with 250+ breed-specific genetic health checks. - Stable, Gentle Temperament Evaluation
Only dogs with calm, confident, and friendly personalities are considered—ideal traits for lifelong companions. - Conformation to AKC Breed Standards
Size, structure, gait, and overall presence are reviewed to ensure alignment with the official English Mastiff breed profile. - Documented Pedigree Analysis for Genetic Diversity
We study lineage to reduce inherited risks and preserve the integrity of the breed’s strongest traits. - Purposeful Pairing for Complementary Traits
Breeding matches are made based on balance—combining structure, temperament, and strengths to build better pups. - Ethical Breeding Practices That Prioritize Well-Being
We follow best practices to protect the health and longevity of both the sires and dams, including proper timing and recovery between litters.
