About the Pyrenean Mountain Dog
The Pyrenean Mountain Dog, or Great Pyrenees, comes from the French side of the Pyrenees, where it guarded flocks against wolves and bears. It is a large, majestic dog with a thick white or white-marked double coat, a broad head and a calm expression. It was also kept as a guard of homes and estates. It tends to be independent and nocturnal in its watchfulness.
Temperament
Gentle, patient and devoted to its family, but independent and protective. It can be reserved with strangers and likes to bark, especially at night. Training needs patience and consistency.
Exercise
Moderate: daily walks and time in a secure garden. Not a dog for long, intense runs, and it should not be left off lead near roads.
Grooming
Thick double coat that sheds heavily. Brush several times a week and daily when moulting, paying attention to the feathering and behind the ears.
Care & wellbeing
Large breed, so protect joints by keeping lean and limiting hard exercise while growing. Heat management is important, and check the dew claws and ears.
