Australian Shepherd vs Great Pyrenees: What’s the Difference?

Australian Shepherd vs. Great Pyrenees: Which Is Better for Families?

One’s a playful, tireless herder. The other? A majestic, mountain-born guardian with the patience of a monk. If you’re choosing between the Australian Shepherd and the Great Pyrenees, you’re essentially picking between fire and ice—energy and serenity. And no, that’s not an exaggeration.

Both breeds are incredibly devoted to their humans, but they bring wildly different vibes to the table (or should we say, the backyard). The Aussie is all about movement, tricks, and attention—they thrive on work and play. Meanwhile, the Pyrenees watches quietly from the porch, guarding your home with a regal calm that says, “I’ve got this.”

This isn’t a contest of better or worse—it’s about what kind of dog lifestyle you want. Are you the type who wants an energetic shadow that keeps you on your toes? Or a low-key, fiercely loyal protector who quietly commands the yard?

In this face-off, we’ll compare temperament, energy, grooming, and more—so you can confidently choose the fluffy co-pilot that matches your pace, personality, and living space.

Australian Shepherd vs. Great Pyrenees

Size and Weight Difference

When it comes to herding dogs, the Australian Shepherd breed and Great Pyrenees might both say, “I’m here to watch the flock,” but they couldn’t be more different in size—and that’s where the fun begins.

Australian Shepherd:

Once bred exclusively for herding, the Australian Shepherd has since grown into one of North America’s most beloved companion dog breeds, as per Wikipedia. Think of the Aussie as the sporty, energetic friend who’s always ready for action but fits perfectly in your car’s backseat.

Australian Shepherd

Compact, muscular, and built for speed and smarts, this breed is like the Ferrari of herding dogs—quick on its feet with plenty of attitude.

  • Height: 18–23 inches

  • Weight: 40–65 lbs

  • Build: Medium-sized, lean but sturdy—made to run circles around trouble (or squirrels)

If agility were a sport, the Aussie would have a gold medal and a cheer squad.

Great Pyrenees:

Now meet the Great Pyrenees—the gentle giant who looks like it just stepped off a snowy mountaintop wearing a fluffy white cape. This dog isn’t just big; it’s “I can probably carry you if you get tired” big.

According to the American Kennel Club (AKC), often called ‘majestic,’ Great Pyrenees are large, powerful mountain dogs with a majestic coat and a calm, commanding presence. This breed is the ultimate protector of sheep and hearts alike.

Great Pyrenees
  • Height: 25–32 inches

  • Weight: 85–115 lbs

  • Build: Large breed dog, strong, and built like a snowy fortress with paws to match

The Great Pyrenees is the generally larger dog version of a giant teddy bear… if that bear was also your bodyguard.

Comparing Trainability and Intelligence

Australian Shepherd:

  • Learning Style: Responds best to positive reinforcement and consistent training with variety to keep their interest.

Great Pyrenees:

  • Trainability: Moderate — Pyrenees are intelligent but have an independent, sometimes stubborn streak. They’re bred for guarding, which means they often think for themselves rather than just obey commands.

  • Intelligence: Smart in their own right, with excellent instincts for protection and decision-making, but not always eager to please or quick to obey.

  • Learning Style: Patient, calm, and steady training works best; they need gentle guidance and consistency.

Australian Shepherd:

Australian Shepherd

Aussies are the ultimate adaptable dynamos. Whether it’s city life, country roads, or hiking trails, they’re ready to jump in and make the best of it, as long as they get enough mental and physical exercise.

  • Adaptability: High — adjusts well to different environments, including apartments (with plenty of walks!)

  • Independence: Low to moderate — loves being with people and working alongside their humans

  • Potential Challenges: Boredom can lead to mischievous behavior if not mentally stimulated

Great Pyrenees:

Great Pyrenees

Pyrenees are the calm rulers of their domain. They adapt best to quieter, more spacious environments where they can keep an eye on their territory. They like routine and tend to be more independent thinkers.

  • Adaptability: Moderate — prefers rural or suburban homes with large yards; less suited to busy urban life

  • Independence: High — they think for themselves and aren’t eager to follow orders blindly

  • Potential Challenges: Can be stubborn and less flexible with changes or new environments

Bite Force and Characteristics

In a nutshell, the Aussie’s bite is quick and controlled for herding finesse, while the Great Pyrenees packs the power of a true guardian, ready to protect when the situation calls for it.

Australian Shepherd:

Australian Shepherd
  • Bite Force: Moderate — around 200 to 300 PSI (pounds per square inch), which is typical for medium-sized herding dogs. Not the strongest bite, but don’t underestimate their quick reflexes!

  • Biting Style: Aussies use their mouths gently when herding livestock, known as “herding nips” — more like a firm tap than a full-on bite. They’re smart enough to know when to hold back, but if threatened or scared, they’ll defend themselves fiercely.

Great Pyrenees:

  • Bite Force: Strong — roughly 500 to 600 PSI, reflecting their role as livestock guardians needing to deter large predators like bears or wolves. Their bite packs a serious punch when needed.

  • Biting Style: Protective and deliberate — they’re not mouthy dogs by nature, but will use their powerful bite decisively if guarding family or flock. Usually, their presence alone is enough to warn off threats.

Nutritional Needs and Weight Management for Australian Shepherd vs Great Pyrenees

Feeding a dog is more than filling a bowl—it’s about fueling their unique bodies and lifestyles. Whether it’s the agile Aussie or the fluffy Pyrenees, understanding their nutritional needs is key to keeping these pals in peak form without packing on unwanted pounds.

Australian Shepherd:

Australian Shepherd
  • Calorie Needs: Moderate to high — Aussies are energetic, lean, and muscular, needing around 1,000 to 1,600 calories per day, depending on age, size, and activity.

  • Diet Focus: High-quality protein to support muscle tone, healthy fats for energy, and balanced carbs for stamina. Because Aussies are active learners and athletes, they benefit from nutrient-dense food and balanced portions.

  • Weight Management: Aussies have a healthy appetite but can gain weight if under-exercised. Average exercise combined with portion control helps keep them fit and agile.

Great Pyrenees:

  • Calorie Needs: Higher calorie requirements due to their large size, roughly 2,000 to 3,000+ calories per day depending on weight, activity, and metabolism.

  • Diet Focus: Balanced diet rich in protein and joint-supporting nutrients (like glucosamine) to maintain their strong frame and prevent common joint issues. Because they’re less active than Aussies, controlling calorie intake is crucial to avoid obesity. PetMD noted that Great Pyrenees thrive on dog food formulated for large breeds. Be sure to select a formula that matches your dog’s specific life stage for optimal health.

  • Weight Management: These gentle giants can easily gain excess weight if overfed or under-exercised, which can stress joints. Portion control and regular, moderate exercise are key.

Grooming Requirements and Allergy Considerations

    • Brushing 2–3 times a week to manage shedding and prevent tangles

    • More frequent brushing during seasonal “blowouts” (shedding spells)

    • Occasional baths to keep the coat fresh

  • Allergy Considerations:

    • Moderate shedding can be a challenge for allergy sufferers

    • Regular grooming helps minimize loose hair and dander
