Pyrenean Shepherds are medium-sized dogs. Adult males typically weigh between 30-50 pounds, while females usually range from 25-45 pounds. Their height generally measures around 15-21 inches at the shoulder, making them agile and well-suited for their herding duties.

Pyrenean Shepherds are known for their intelligent, energetic, and loyal temperament. They are friendly and affectionate with their families, often forming strong bonds with their human companions. These dogs are alert and have a natural instinct to protect their herd, which can manifest in their interactions. They require consistent training and socialization to manage their independent streak and ensure well-behaved adults.

The coat of the Pyrenean Shepherd varies by variety. The Smooth-Faced variety has a short, dense coat that lies flat against the body, while the Rough-Faced variety has a longer, wavy coat. Both varieties may come in various colors, including fawn, gray, black, and white, with potential markings. Regular grooming is necessary to maintain their coat; the Rough-Faced variety requires more frequent brushing to prevent matting.

This breed thrives in active environments where they can receive ample exercise and mental stimulation. Pyrenean Shepherds are well-suited for rural settings where they can work and roam freely, but they can also adapt to family life in suburban settings. They do best when included in family activities and do not like to be left alone for long periods, as they enjoy companionship.

Pyrenean Shepherds excel in various activities that allow them to utilize their herding instincts and high energy levels. Daily walks, runs, and playtime are essential for their well-being. They thrive in tasks involving livestock herding and can participate in dog sports such as agility, obedience, and herding trials. Providing mental challenges through interactive toys or training exercises is also beneficial for their overall happiness.
