Description
Lyra’s Multigenerational Mastiff Puppies
Lyra’s puppies are thoughtfully bred multigenerational Mastiff-type dogs, developed with a strong focus on health, structure, temperament, and real-world family compatibility. These are not first-generation crosses. Each generation in our program is intentionally selected to preserve Mastiff substance and presence while prioritizing sound movement, longevity, and balanced, stable temperaments.
Lyra herself is an exceptionally balanced female…steady, people-focused, emotionally intuitive, and naturally nurturing. She brings a calm confidence and excellent social awareness to her puppies, and those qualities are already evident throughout the litter.
This group is showing excellent engagement with people, strong recovery from new experiences, and thoughtful curiosity. The puppies demonstrate a nice balance between confidence and composure, making them adaptable companions for a wide variety of homes. Temperaments range from cuddly and gentle to playful and driven, allowing for thoughtful placement based on individual personality rather than just appearance.
Structurally, these puppies are developing with solid bone, balanced proportions, and functional athleticism, staying true to Mastiff type without sacrificing mobility or soundness.
All puppies are raised in our home (never kennels) and are exposed daily to normal household activity, people, children, other dogs, and structured enrichment. We follow Puppy Culture–based early development practices including early neurological stimulation, confidence-building exercises, problem-solving, and intentional human interaction to help create emotionally resilient, people-oriented dogs.
Each puppy goes home with:
• Age-appropriate vaccinations and deworming
• Microchipping
• Veterinary health exam
• Early training and socialization foundations
• Lifetime breeder support
• Temperament Testing
Ear crops have been completed on this litter and are included, along with aftercare guidance.
These puppies are ideal for families, active homes, or owners looking for a thoughtfully bred Mastiff companion with stable nerves, strong structure, and the ability to integrate seamlessly into daily life.
We prioritize matching puppies based on temperament and lifestyle fit rather than color alone.
Serious, well-matched homes only. Financing available to vetted and approved homes. If you are interested in this litter please visit our website at www.monumentalmastiffs.com to complete an application.
Lyra’s Yellow Collar male is a quiet, thoughtful puppy with a huge heart. He’s the kind of pup that naturally bonds deeply with his people and is shaping up to be a true heart dog…deeply connected, emotionally intuitive, and happiest when close to his humans.
He is very focused and biddable, responding easily to interaction and guidance, which makes him a joy to work with even at this young age. His temperament leans toward calm and cooperative, and he carries himself with a gentle confidence rather than boldness.
This boy is incredibly easy to live with, he doesn’t seek conflict, isn’t demanding, and moves through his environment quietly and sweetly. He truly lives up to being a sweetheart.
An excellent choice for a family or individual looking for a loving, people-oriented Mastiff companion who will thrive on connection, structure, and shared life experiences.
