🐾 Our Breeding Program
At Big Bones Maine Coons and Newfies, our mission is simple: to raise healthy, true-to-type Newfoundland dogs with verified genetics, excellent temperaments, and transparent health information. We combine traditional dedication to the breed with modern science — ensuring every puppy we produce embodies both the spirit and strength of the Newfoundland.
💡 Science-Based Breeding, Not Just Paperwork
While many breeders rely on registration papers to establish “purity,” we go a step further. Every Newfoundland in our program is DNA-tested through Embark, the most comprehensive canine genetic testing platform available today.
Embark doesn’t just assume a dog’s breed based on ancestry reports — it verifies breed identity through DNA analysis. That means when we say our dogs are 100% Newfoundland, it’s backed by science, not just breeder paperwork.
Our commitment to DNA verification gives buyers confidence that their puppy’s breed identity is proven in the lab, not merely recorded on paper.
🧬 Health You Can See in the Genes
Genetic health is at the heart of everything we do. Both of our breeding dogs were screened through Embark for over 230 hereditary diseases, including those known to affect Newfoundlands such as:
Cystinuria (Type I-A)
Subvalvular Aortic Stenosis (SAS)
Degenerative Myelopathy (DM)
Progressive Retinal Atrophy (PRA)
We carefully paired our dogs based on genetic compatibility and inbreeding coefficients (COI) to maintain diversity and reduce the risk of inherited conditions. This helps ensure our puppies are not only beautiful and true to breed, but healthy and long-lived.
🐕🦺 Transparency and Trust
We believe that buyers deserve complete honesty and openness. That’s why every family who adopts a puppy from us receives:
A copy of both parents’ Embark breed and health reports, including the page which confirms 100% Newfoundland DNA
