The Great Pyrenees, known for their majestic appearance and gentle demeanor, is a breed that has captured the hearts of many dog enthusiasts. One frequent question that emerges when discussing this breed is regarding its bite force. Just how powerful is the bite of a Great Pyrenees, and does it hurt? Let’s dive deep into understanding the bite force of the Great Pyrenees and its potential implications.

Understanding the Bite Force of a Great Pyrenees

When discussing the bite force of a Great Pyrenees, it’s important to recognize that, like any dog breed, the power behind its jaws can be significant. The bite force is typically measured in pounds per square inch (PSI). For comparison, a human’s bite force ranges around 120-140 PSI, while some of the strongest canine bites, like that of a Rottweiler or Mastiff, can reach over 300 PSI.

While the Great Pyrenees isn’t primarily bred for its bite strength, its size and heritage as a livestock guardian dog indicate that it does have a substantial bite. Estimations suggest that the bite force of a Great Pyrenees ranges between 220-240 PSI. This means the Great Pyrenees has a stronger bite than humans but aren’t at the top of the canine bite force list.

How Does the Bite Force of a Great Pyrenees Compare to Other Breeds?

In the canine world, the Great Pyrenees possess a respectable bite force. It’s important to note, however, that bite strength can vary among individual dogs due to factors such as health, training, and genetics. The Great Pyrenees’ bite force is stronger than many other breeds but is overshadowed by breeds specifically known for their jaw strength.

For instance, breeds like the Belgian Malinois or German Shepherd, often used in police and military roles due to their bite strength, tend to have a bite force that surpasses that of the Great Pyrenees. Nonetheless, the bite force of the Great Pyrenees is still impressive and should be respected.

Does a Bite from a Great Pyrenees Hurt?

Absolutely. Given its bite force, a bite from a Great Pyrenees can indeed be painful and can inflict serious injury. While the breed is generally known for its gentle disposition, especially towards its family, any dog has the potential to bite under certain circumstances.

The actual pain and potential damage from a bite will depend on various factors, including the location of the bite, the duration of the bite, and the individual dog’s intentions (e.g., a warning nip versus a more aggressive bite). But with the bite force of a Great Pyrenees taken into consideration, it’s safe to say that such a bite would be more painful than that of many smaller breeds.

Why Might a Great Pyrenees Bite?

Understanding the temperament of the Great Pyrenees is crucial when discussing its bite potential. Historically, the Great Pyrenees was bred to guard livestock against predators. This required a combination of patience, bravery, and occasional assertiveness. This breed can be protective, and while they’re generally calm, they can act if they perceive a threat to their family or charges.

Most cases of biting incidents, not just with the Great Pyrenees but with dogs in general, stem from fear, pain, or the need to establish dominance. Proper training, early socialization, and understanding of the breed’s temperament are critical to prevent unwanted aggressive behaviors.


While the Great Pyrenees is often lauded for its calm demeanor and loyalty, it’s essential to respect the power behind its jaws. The bite force of a Great Pyrenees is indeed substantial, and it can cause pain and injury if the dog chooses to use it. As with all dogs, responsible ownership, training, and understanding of the breed’s unique characteristics are key to ensuring harmonious interactions and preventing any potential biting incidents.

Frequently Asked Questions About Great Pyrenees Bites

1. Why do Great Pyrenees puppies often resort to biting?

Great Pyrenees puppies, as with most puppies, go through a teething phase where their gums become sore and itchy. To ease this discomfort, they naturally chew or bite on various objects, such as toys or even people’s fingers. It’s crucial during this phase to provide them with appropriate chew toys and instill bite inhibition training.

2. Are Great Pyrenees naturally aggressive biters?

No, the Great Pyrenees are not inherently aggressive. They are best known for their calm and patient nature. However, being historically bred as livestock guardian dogs, they have a protective instinct and may exhibit assertive behavior when they perceive threats.

3. How can I prevent my Great Pyrenees from biting?

The key to curbing biting behavior in the Great Pyrenees is early socialization and consistent training. Expose your dog to a variety of environments, people, and other animals from a young age, and employ positive reinforcement techniques to teach appropriate behavior.

4. Why do my Great Pyrenees occasionally nip at people’s heels?

This heel-nipping behavior is often linked to the breed’s history as a herding and guarding dog. Nipping at heels was a method used by many herding breeds to direct livestock. Although instinctual, this behavior can be managed with proper training.

5. Is a bite from a Great Pyrenees dangerous?

Any dog bite can pose risks, and given the size and strength of the Great Pyrenees, a bite can indeed be harmful. It’s essential to understand and respect the potential strength behind their bite and to address any aggressive tendencies immediately.

6. What triggers a Great Pyrenees to bite?

While every dog is unique, common triggers for biting in the Great Pyrenees may include fear, pain, territorial behavior, or protective instincts. Being aware of these triggers and managing situations appropriately can help in preventing aggressive incidents.

7. How do I teach bite inhibition to my Great Pyrenees puppy?

Bite inhibition is best taught by allowing your puppy to interact with other well-behaved dogs, as they naturally correct each other during play. Additionally, when your puppy bites too hard during play with you, respond with a sharp “ouch” and cease playing momentarily, signaling that the behavior is unacceptable.

8. Can adult Great Pyrenees be trained not to bite?

Absolutely. While training an older dog may require more patience and persistence, with consistent training methods and possibly the assistance of a professional dog trainer, adult Great Pyrenees can learn to curb their biting behavior.

9. Do male Great Pyrenees bite more than females?

Biting is not necessarily linked to the gender of the dog. Factors like individual temperament, past experiences, training, and socialization play a more significant role in determining a dog’s propensity to bite than their gender alone.

10. Are there specific toys or tools that can help curb biting in Great Pyrenees?

Durable chew toys, puzzle toys, and interactive feeders can be effective in redirecting the biting instinct of a Great Pyrenees. These tools can help satiate their natural desire to chew, especially during their teething phase, and keep them mentally stimulated, reducing unwanted behaviors.
