Muddy Mastiffs is an English Mastiff Dog Breeder in Pennsylvania
Muddy Mastiffs is a third generation English Mastiff dog breeder in Pennsylvania. We specialize in AKC English Mastiff puppies for sale in PA bred for giant size, structure, temperament, and DNA health-tested bloodlines.
Our giant English Mastiff bloodlines reach up to 250 pounds at maturity. But we don't chase the scale. We select for bone structure and then just focus on health.
We are blessed to have descendants from some elite bloodlines. Current four generation pedigrees include a Double Platinum Grand Champion, 2 Silver Grand Champions, 2 Bronze Grand Champions, 5 additional Grand Champions, and 11 Champions... some of the most influential Mastiffs in modern show history.
As a third generation program, we select heavily on maternal instincts. Then we raise puppies with Early Neurological Stimulation for a calm temperament. This ENS program didn't start with us. It started with the US military and has some amazing health and personality benefits. It used to be called the Bio Sensor Program and then became known as the Super Dog Program. You definitely want to read all about it here.
Show prospects and foundation puppies are occasionally available. If you are serious about getting a puppy from us, you need to get on the waiting list ASAP. Then text Alissa at 570-765-1878 to become an approved home.

Meet Our Dogs
Current Stud
Freedom (AKC Champion)
Freedom just won his Championship within less than 4 days of being shown. On the 5th day he competed against the #1 Mastiff in America for Grand Championship points and took Select Dog both days. We expect him to become a Grand Champion.
Freedom is heavily line bred from Hollesley Medicine Man, arguably the greatest show Mastiff of all time, who appears at least 66 times in his pedigree, with a heavy concentration around generation 10-12. More recently, he is line bred on GCH CH Deer Creek's Cletus II. Freedom's father, CH Deer Creek's Otis, is a Cletus son. And Freedom's mother is a full sibling to Cletus. The male line weighs in around 235-250. At 18 months, Freedom currently weighs about 190 with room to grow.
Retired First Generation Female
Nena
Nena was the best mother you ever met, naturally whelping large litters and raising them throughout the most challenging growth seasons. Nena is anchored by a Grand Champion Silver appearing as her grandfather, an exceptionally close and meaningful placement of elite show recognition. Within just four generations, her pedigree reflects a dense concentration of Champion-titled dogs, combining proven structure, consistency, and generational quality that serious programs are built on.
Retired First Generation Stud
Bane
Bane is built on a pedigree that blends international influence with proven American show lines. Within just 4 generations, his lineage includes an imported Russian Champion, a Grand Champion, and multiple Champions known for structure, substance, and consistency.
His pedigree reflects a thoughtful balance of size, stability, and long-term breed integrity, bringing together lines that have produced both ring success and dependable, real-world Mastiffs. We love that he represents genetic diversity and size in our line.

Preservation Breeding Philosophy
Our Mastiff bloodlines traces back to the near extinction of the Mastiff breed. Thankfully it was brought back, and it falls to breeders like us to preserve and continually improve the genetics we manage.
Functional Structure
Although we do breed for muscular/skeletal size, we keep our dogs functional and fit with a 3 step process.
β
-
We do NOT regularly weigh our Mastiffs.
-
We free feed as much healthy hard food as they want. It's boring enough that they mostly just eat when they are hungry.
-
We do not free feed wet food, cooked food, or treats. So even though they get something special almost every day it's hard for them to overeat on calories.
-
We give them lots of exercise in the Pennsylvania mountains.
β
One of the comments we get most on our YouTube is how functional and fit our dogs look.
Apparently it's a thing in the Mastiff world to overfeed a sedentary dog and then brag about how much it weighs.
We would rather select for structural size when we make pairing decisions and then keep our puppies really healthy and fit while they are growing.
Temperament Focus
We select for temperament. Our dogs stand on business when facing a threat. Otherwise they are great with strangers.
OFA Health Testing
We are in the process of health testing our dogs. And we make responsible breeding decisions to support long, healthy lives. CHIC numbers will be provided upon completion.
Show Presence
We are a show kennel. Our stud, Freedom, recently won his Championship within less than 4 days of being shown. On the 5th day he started competing for Grand Championship points against the #1 Mastiff in America, taking Select Dog in both shows. He is likely going to become a Grand Champion.
Multigenerational Program
We are proud to own our third generation of female English Mastiffs.
We will continue to hold back daughters from our own line, improving them with each generation through the use of complimentary studs.
β
We are developing that "once in a lifetime" line that has both functional soundness and show structure.
Family Raised Puppies
Puppies are raised by our family in the beautiful Pennsylvania countryside. We are a 3-person team. My name is Alissa. I handle most of the online stuff, pedigree analysis, pairing decisions, and whelping. My husband, Jason, handles most of the customer contacts, and as a combat veteran, he added the millitary "Super Dog" ENS process to our program before it was cool. My dad, Greg, handles most of the infrastructure planning, building, and animal husbandry advice, as he comes from generations of farmers. We all work together to manage the day to day needs of the dogs.
