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.

The MLJ Mastifff's Breeding Philosophy

More Than Just Big Dogs, We Breed Gentle Giants.

At MLJ Mastiffs, we breed with purpose. We’re committed to improving the English Mastiff breed through:

Selective pairing for ideal bone structure and size
Close observation of temperament from day one
Daily socialization and exposure for well-balanced behavior

Gentleness isn’t guaranteed by genetics alone—it’s shaped through care, patience, and understanding. That’s what we do every single day.

What Sets Us Apart

Health, Heritage & Unmatched Care

We don’t stop at bloodline. Our English Mastiffs are thoroughly screened and raised to thrive. What makes MLJ Mastiffs different?

Champion & Grand Champion Bloodlines
OFA Testing – hips, elbows, and heart
250+ Genetic Health Checks for breed-specific risks
Raised indoors in a climate-controlled environment
Supplemented early for immune health and strong development
AKC pedigree, CHIC Certified, DNA for Dog Breeders (Institute of Canine Biology)

We believe better breeding starts with better standards—and the proof is in our puppies.

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.

Brian has always been exceptionally forthcoming, and honest about his mastiffs from day 1. He kept me informed of my pups progress, and vet visits. Bauer came to us at a little over 10 weeks old perfectly healthy, and ready to be loved on. If you’re looking for a mastiff look no further. Brian and his family raise some truly great ones!!!

Megan and Brad Willard here, and we wanted to share our personal experience with MLJ Mastiffs. We had a wonderful experience and couldn’t be happier with our boy, Loki! He just turned one year old this past Saturday and is from Sasha and Turbo’s litter. He has been an absolutely amazing puppy—healthy, loving, great with kids, and wonderful with other dogs.We originally fell in love with the Mastiff breed after rescuing our older Mastiff when he was three years old. Unfortunately, despite being told … read more by a supposedly reputable Florida rescue that he had a clean bill of health, we quickly discovered he was very sick. We spent thousands of dollars getting him healthy. When we decided to get him a Mastiff companion, we knew we wanted to go through a reputable breeder who could provide us with a healthy, well-cared-for puppy.That is exactly what we found with MLJ Mastiffs. Loki has received nothing but wonderful health reports, and our experience from the very beginning has been extremely positive. He adjusted beautifully to our home and immediately did well with our other dogs. Of course, all puppies need time to learn and adjust to their new environment, but Loki has been an incredible addition to our family.Hearing that someone gave MLJ Mastiffs a bad review was extremely disappointing to us because it does not reflect our experience at all. Based on our firsthand experience, we have nothing but positive things to say about them and the care they provide their dogs.We have personally seen the care that goes into these dogs and the clean environment they are raised in. We could not be happier with Loki or our experience with MLJ Mastiffs. He is healthy, happy, well-socialized, and truly one of the best additions to our family.We would absolutely recommend MLJ Mastiffs to anyone looking for a healthy, loving Mastiff puppy. We are so thankful we found them and, most importantly, so thankful for our Loki!— Megan & Brad Willard

You can truly tell how much MLJ Mastiffs cares about the Mastiff breed and where their puppies are going. I even went through a pre-interview of sorts before being placed on the waiting list, which showed me how seriously they take finding the right homes for their puppies. I’m so thankful for their professionalism, care, and for helping us welcome the newest member of our family!

We are proud repeat customers of MLJ Mastiffs and have two puppies from them spaced 10 months apart. Our oldest, Dixie Rose, has the most incredible, gentle, and sound temperament of any dog we’ve ever had. She is the most beautiful, loving, goofy, mastiff-stubborn, cunning, paw throwing girl you’d ever meet. She just melts us! Our 8-week-old puppy, Roxie, is already showing that same sweet and funny, well-adjusted nature, and we can’t wait to see her personality unfold.Brian Jones and his family … read more invest immense care into the early foundations, socialization, and genetics of their dogs. We happily made the 16-hour round-trip drive (incl. doggy stops) both times to pick up our girls, and were impressed with the spacious (air conditioned) facilities and huge pasture size yard. Brian takes great pride in his dogs, keeps in touch constantly, and truly feels like family. We highly recommend MLJ Mastiffs to anyone looking for a top-tier companion!

We found our best friend at MLJ Mastiffs! We had been talking about getting a new family dog but hadn't found the right one until we starting talking to Brian. He gave us our baby Oliver.
