Caring for a Great Pyrenees

Growth-related health concerns include:
Hip and elbow dysplasia
Osteochondritis dissecans (OCD)
Bloat (gastric torsion)
Maintain a lean body condition throughout growth, and consult your vet about joint supplements (like glucosamine and chondroitin) starting in adolescence.

Feed a large- or giant-breed puppy formula with controlled calcium and phosphorus to support proper skeletal development.
Provide 3 meals per day until 6 months of age, then reduce to 2 meals daily.
Avoid overfeeding or excess protein/calories to prevent rapid growth, which increases the risk of joint issues.

To handle their thick double coat, Great Pyrenees need to be brushed once a week with a slicker brush and rake; this frequency is enhanced during significant, twice-yearly shedding.
They require special care for their rear double dewclaws, baths every one to three months, and should never be shaved because this interferes with their ability to regulate their body temperature.

Offer moderate, controlled exercise like short walks and supervised play.
Avoid strenuous activity such as jumping, running long distances, or navigating stairs during the first 18 months.
Provide mental stimulation—the Pyrenees is intelligent and benefits from training games and light obedience work.

The Great Pyrenees, also known as the Pyrenean Mountain Dog, was originally bred to guard flocks in the harsh mountainous regions between France and Spain. Known for their calm demeanor and strong protective instincts, they are loyal and gentle companions—especially with children and livestock. Despite their serene presence, they are independent thinkers with a strong will.

As a giant breed, the Great Pyrenees experiences prolonged growth and development. Tracking their weight and height is essential to prevent overfeeding, joint strain, and orthopedic issues commonly associated with large, fast-growing dogs.
