Meet the breeder

I'm Heather M., the breeder behind Eagle Clan Mastiffs located in Henderson, NV. I breed for quality, health, show, and companionship. I love my dogs and what I do. My program produces healthy, beautiful Mastiff puppies. I take my job seriously, knowing that my puppies will become someone's well-loved pet. Each puppy is considered a member of my family and I ensure they are socialized, healthy, and prepared to excel in their forever homes.

Breeder-Reported Testing

Great level

Eagle Clan Mastiffs reports to performing the health tests below on their breeding dogs. Ask your breeder about the tests performed on the parents of your litter. Learn more about health testing for Mastiffs.

  • Hip Dysplasia

    Hip testing reduces the chance of passing down hip dysplasia, which is primarily found in large breed dogs and can cause hip pain and the eventual loss of the function of the hip joint.

  • Elbow Dysplasia Finals (OFA, BVA, SV, FCI)

    Elbow testing reduces the chance of passing down elbow dysplasia, which is primarily found in large breed dogs and can cause arthritis in the elbow joint and front leg lameness.

  • Cardiac Evaluation (registered with OFA)

    Heart testing reduces the chance of passing down congenital heart disease, which can cause a range of symptoms ranging from trouble exercising to heart failure.

  • Thyroid (Autoimmune Thyroiditis, registered with OFA)

    A breeder may perform additional tests on their dogs that do not fall into these general categories. These tests may be more uncommon or very specific to a particular breed.

  • Degenerative Myelopathy (DM; SOD1A), Early Onset Progressive Retinal Atrophy (EOPRA), Multifocal Retinopathy 1 (CMR1)

    Genetic testing reduces the chance of passing down a wide variety of hereditary diseases of differing prevalence and severity such as Progressive Retinal Atrophy (an eye disease) and Von Willebrand's Disease (a blood disease).
