Available Pyrenean Mastiff Puppies and Upcoming Litters
At Reis D'Aragón, we have been breeding Pyrenean Mastiffs since 2009, following a family-based and responsible approach. This large, noble and protective breed is well suited to families living in houses with land or rural properties who are looking for a balanced and reliable companion.
Our puppies grow up in a calm environment, with constant care and early socialisation from their first weeks of life, allowing them to develop into trustworthy and affectionate guardian dogs, capable of living with children and protecting the home while maintaining a gentle temperament.
Confirmed upcoming litter · February 2026
After confirming the pregnancy by ultrasound, we are looking forward to the arrival of the next Pyrenean Mastiff litter at Reis D'Aragón. The puppies are expected to be born in February 2026.
Parents of the litter
In the selection of each breeding pair, we seek a balance between corect morphology, temperament, nobility and the characteristic breed type of the Pyrenean Mastiff.
Both the sire and the dam of this litter are part of a breeding programme based on experience, daily coexistence and a genuine understanding of the breed, always guided by a responsible, long-term vision.
Sire: Kaiser de las Palmeras de la Dehesa
Kaiser de las Palmeras de la Dehesa is a young male who stands out for his strong structure, solid bone and a poweful, well-defined head. He is a massive dog, with a presence that fully reflects the traditional type of the Pyrenean Mastiff.
He comes from a lineage we particularly value, contributing consistency and breed type to the pairing. Despite his young age, he is already beginning to stand out in dog shows, showing very promising development both in morphology and attitude.
Dam: Fire de Reis D'Aragón
Fire de Reis D'Aragón is a female who is perfectly integrated into everyday family life. She stands out for her noble temperament, stability and her natural, calm relationship with people.
From a morphological point of view, she is a rather tall female with a solid structure, good bone and a well-proportioned, feminine head. Her overall balance and temperament make her a very important foundation within our breeding programme, reflecting the functionality and character we seek in our brood females.
How we raise and place our puppies
At Reis D'Aragón, we breed Pyrenean Mastiffs following a family-based and responsible approach. We limit the number of litters in order to ensure that each puppy receives the individual attention needed to grow into a well-balanced adult dog.
Our goal is to raise large, noble and stable dogs, without losing the functionality and agility characteristic of the Pyrenean Mastiff, suitable for responsible families who have adequate space and understand the needs of the breed.
How do our puppies grow?
Family environment: They are born and raised in our home, exposed to everyday sounds, people and other dogs. This early socialisation is the foundation of their future character.
Respect for their development: We place puppies only when they have reached the appropriate level of maturity, never too early, after remaining with their mother and littermates during the first weeks of life.
Functional health: Puppies are delivered with a complete vaccination schedule (three doses), fully dewormed and under continuous veterinary supervision from birth.

Is the Pyrenean Mastiff right for you?
The Pyrenean Mastiff is an extraordinary dog, but it is not a breed suitable for everyone. Before welcoming a puppy into your family, it is important to carefully consider its needs and the type of life you can offer.
Size, strength and character
This is a very large and powerful dog, with a noble and well-balanced temperament. Although stable and confident, it requires consistent training from puppyhood in order to become a manageable adult. Its size and strength make responsible and conscious ownership essential.
Space and environment
The Pyrenean Mastiff needs to live in houses with ample land, gardens or rural properties, where it can move freely and naturally develop its guarding instinct. It is not a suitable breed for apartment living or urban environments.
Long-term commitment
Living with a Pyrenean Mastiff means assuming responsibility for its entire lifetime. It requires appropriate nutrition (especially important during its rapid growth), care adapted to its size and a constant commitment from its family.
Welcoming a Pyrenean Mastiff means welcoming a loyal protector and a calm companion. If you have the space and the time this breed deserves, the reward will be unmatched loyalty.
Information for interested families
If you are interested in this upcoming Pyrenean Mastiff litter, we recommed getting in touch with us in advance. We breed only a few litters, and we prefer to get to know families ahead of time, speak calmly and answer any questions before the time arrives.
We like to understand what you expect from the breed, the type of life you can offer, and to explain transparently how we work. We are not in a hurry, nor do we seek forced commitments: we believe that good decisions are made throug information and mutual trust.
