Understanding the Health and Care of Your Great Pyrenees

Quick answer

The Great Pyrenees is a devoted and calm companion that thrives with consistent, gentle guidance and thoughtful environmental management. While generally robust, owners should be aware of specific health considerations, including the potential for laryngeal paralysis and osteosarcoma. By maintaining a lean body condition and providing appropriate support for their joints and temperature regulation, you can help manage their long-term well-being effectively.

Laryngeal Paralysis

Laryngeal paralysis involves the muscles of the voice box failing to function correctly, which can interfere with normal breathing. In this breed, this is a recognised tendency rather than a proven one. It is important to note that a form of this condition, known as the laryngeal paralysis-polyneuropathy complex, has been reported in young dogs under one year of age. How this passes down is not settled.

At home, you might first notice a change in the sound of your dog's bark, which may become raspy or weaker. You may also observe noisy, labored breathing, especially when your dog is active, excited, or exposed to warm temperatures. If you notice your dog struggling to catch their breath or exhibiting a high-pitched sound while inhaling, this requires prompt attention.

Your veterinarian will perform a physical examination and likely recommend a laryngeal exam under light sedation to observe the movement of the laryngeal cartilages directly. This observation is the standard way to confirm the condition. If your dog is in respiratory distress, the situation is urgent, and they will need immediate stabilization, which may include oxygen therapy and cooling measures.

Osteosarcoma

Osteosarcoma is a type of bone tumor that can affect large breeds. In the Great Pyrenees, this is a recognised tendency rather than a proven one. While it has been documented in clinical reports, including cases involving the distal radius, how this passes down is not settled.

As an owner, you should watch for any unexplained lameness or a persistent limp that does not improve after a few days of rest. You might also notice localized swelling or a firm, painful lump over a limb. Because these signs can be subtle at first, they are often mistaken for a simple sprain or injury from play.

Your veterinarian will typically perform a physical examination followed by diagnostic imaging, such as radiographs, to evaluate the bone structure. If a suspicious lesion is identified, further tests like a biopsy or advanced imaging may be required to reach a definitive diagnosis. It is vital not to dismiss a persistent limp as just 'growing pains' or a minor bruise, as early detection is key to managing your dog's comfort.
