It is an extraordinary and rare sight to see six generations of a giant dog breed together in one photograph. In giant breeds such as the Pyrenean Mastiff, this is especially remarkable, as their average lifespan is generally shorter than that of smaller breeds.

This unique image comes from Gaspalleira Kennels in Spain, owned by Ana and Roberto, respected breeders from the A Coruña region. They have dedicated many years to breeding Pyrenean Mastiffs, with puppies exported to numerous countries around the world.

The photograph shows, from left to right:

• • Vacaburra de Gaspalleira — 4 years and 3 months

• • Mauria de Gaspalleira — 6 years and 5 months

• • Faisca Branca de Gaspalleira — 2 years and 4 months

• • Xeitosa de Gaspalleira — 10 years and 4 months

• • Rojas de Gaspalleira — 7 weeks

• • Thundra de Moralet — 13 years

The image naturally raises an important question: is breeding healthy dogs the key to longevity?

Ana Jacob believes it is an essential foundation.

“I believe that breeding healthy dogs is vital to the survival of our breed. When a family decides to take on a Pyrenean Mastiff puppy, they know it will be an expensive dog to maintain, but worthwhile for its wonderful temperament and imposing appearance.”

However, responsible breeding alone does not guarantee lifelong health.

Ana explains that the puppy’s first year of life plays a crucial role in its future development and well-being.

“No matter how much a breeder tries to breed healthy puppies, the care a puppy receives during its first year of life is fundamental for its later health and to prevent problems such as muscle and bone issues. Keeping the puppy slim to slow its growth — the puppy’s final size will remain the same, it will simply be reached more gradually — allowing free exercise without forcing it, keeping it on soft, non-slip surfaces such as grass, avoiding slippery indoor floors, preventing the puppy from going up and down stairs, and providing supplements to protect the joints throughout growth are all essential measures that the new family must provide.

A healthy Pyrenean Mastiff is the result of both the breeder and the owner working together: the breeder carefully selecting healthy parents and properly raising the puppies, and the new family understanding and applying the necessary care for harmonious growth. After the first year of life, they will have a healthy dog that can be enjoyed under the same conditions as any other dog.”

The Pyrenean Mastiff remains a rare breed that requires careful and responsible breeding practices, with genetic diversity playing a critical role in its future.

Breeding healthy dogs is becoming increasingly important as the European Union moves toward stricter animal welfare legislation. In addition, many kennel clubs are introducing more demanding breeding regulations. Dogs that do not comply with EU or local breeding requirements may no longer be approved for breeding, and pedigrees may not be issued for litters that fail to meet these standards.

These regulations may include mandatory health testing such as hip dysplasia (HD), elbow dysplasia (ED), patella luxation screening, as well as monitoring inbreeding coefficients and genetic diversity. For breeders, complying with these requirements will become essential, especially when using semen or breeding dogs from other countries. Health screenings will need to follow FCI protocols or be supported by official veterinary documentation.

The ultimate goal behind these new regulations is clear: to encourage the breeding of healthier dogs with greater genetic diversity, helping preserve breeds like the Pyrenean Mastiff for future generations.
