10 Best Giant Dog Breeds for First-Time Owners (2026 Guide)

You picture a huge, gentle dog leaning against your leg. Then you wonder: can a first-timer actually handle that much dog?

I’m Thomas Cutter, and I’ve spent years researching and writing about dog breeds for new owners. Giant breeds like the Great Dane and Newfoundland scare off a lot of beginners. That’s usually the wrong call.

Some giant breeds are far easier than people expect. Others need real experience first. This guide shows you which is which, so you can pick with confidence. Let’s get into the breeds that actually make sense for a first dog.

What Makes a Dog Breed “Giant”?

A giant dog breed is one that typically weighs over 90 pounds as an adult and stands at least 26 inches at the shoulder. This category includes Great Danes, Mastiffs, Saint Bernards, and Newfoundlands. Size alone does not predict temperament. Many giant breeds are calmer and easier to live with than smaller, higher-energy dogs.

Most kennel clubs do not use one official cutoff for “giant.” But breeders and vets generally agree the line sits around 90 to 100 pounds at maturity. Below that, a dog is usually called “large,” not “giant.”

Here’s why that distinction matters for a beginner. A large breed mistake, like an untrained 60-pound Labrador, is annoying. A giant breed mistake, like an untrained 150-pound Mastiff, can be dangerous. You might be thinking size is the main risk. Here’s why that’s only half true: an untrained giant breed is the real risk, not the breed itself.

That’s the real reason this guide exists. I want you to walk away knowing which giant breeds forgive beginner mistakes, and which ones punish them.

The 10 Best Giant Dog Breeds for First-Time Owners

This list ranks giant breeds by how forgiving they are for someone new to dog ownership. Each one balances size with trainability, patience, and a temperament that suits a learning curve.

Giant Dog Breed Comparison Table

The biggest differences between giant breeds come down to energy, grooming, and how easy they are to train. Great Danes and Mastiffs offer low grooming and calm energy. Newfoundlands and Leonbergers need heavy coat care. The Alaskan Malamute stands out as the most active breed on this list.

Which Giant Dog Breed Is Right for You?

The right giant breed depends on your living space, climate, and how much grooming you’ll commit to. Apartment dwellers do best with calm, low-energy breeds like the Great Dane or Mastiff. Active owners suit the Alaskan Malamute. Rural owners with land suit guardian breeds like the Great Pyrenees or Anatolian Shepherd.

Here’s a simple way to match your situation to the right breed.

• If you live in an apartment or small home → a Great Dane or Mastiff fits best, since both are calm indoors despite their size
• If you have kids and want a patient companion → a Bernese Mountain Dog or Newfoundland fits best
• If you live somewhere hot → avoid heavy-coated breeds like the Newfoundland or Malamute, and consider a Great Dane instead
• If you have rural land and want a guardian → a Great Pyrenees or Anatolian Shepherd fits best
• If you’re active and love the outdoors → an Alaskan Malamute matches your pace

This guide covers giant breeds suited to first-time owners in a typical home setting. If your situation involves working livestock guardianship on a large farm, you may need breed-specific guidance from a livestock guardian dog association instead.

Giant Dog Care Essentials Every New Owner Should Know

Giant breeds need joint-safe exercise as puppies, larger food budgets, and more frequent vet checks than smaller dogs. Skip high-impact exercise like jumping or long runs until growth plates close, usually around 18 to 24 months. Feed a large-breed puppy formula to support slower, controlled bone growth.

Most new owners know dogs need food, walks, and vet visits. Fewer realize giant breed puppies need their growth managed carefully. So what does that mean? A giant breed puppy that jumps off furniture too often or runs too hard too young risks joint damage that lasts a lifetime.

Food costs add up fast with a 150-pound dog. As a result, budget for a large bag of large-breed food every two to three weeks, not every month like you might expect with a smaller dog.

Vet visits matter more too, since giant breeds face higher rates of hip dysplasia and heart conditions. Most experts agree that early screening catches problems before they become serious.

What Most People Get Wrong About Giant Dog Breeds

The biggest myth is that giant breeds need more exercise than smaller dogs. In reality, many giant breeds, like the Great Dane and Mastiff, have lower energy levels than a Labrador or Border Collie. The real challenge with giant breeds is space, food cost, and a shorter lifespan, not daily exercise demands.

Most first-time owners assume “bigger dog” means “needs more walking.” That’s often backward. Even better, many giant breeds are calmer at home than popular mid-sized breeds.

You might be thinking a giant breed must be harder to control on a leash. Here’s why that’s only partly true: leash training before the dog reaches full weight solves most of this issue entirely.

When a 12-week-old Great Dane puppy starts obedience class early, leash manners stick well before the dog hits 100 pounds. That taught me that the training window matters more than the breed’s eventual size.

Mistakes New Giant Dog Owners Make (And How to Avoid Them)

The most common mistake is skipping puppy training, assuming a “gentle giant” breed won’t need it. Even calm breeds become hard to manage at 100+ pounds without basic commands. Other common mistakes include over-exercising puppies and underestimating food and vet costs.

• Skipping puppy obedience classes because the breed “seems calm”
• Letting puppies jump on furniture before joints fully form
• Choosing a high-energy giant breed for a small living space
• Underestimating monthly food and vet costs
• Not researching breed-specific health risks before buying

In other words, most giant breed problems trace back to one thing: starting training too late. A 12-week-old puppy is easy to redirect. A 100-pound adult is not.

Frequently Asked Questions

Are giant dog breeds good for first-time owners?

Yes, many giant breeds suit first-time owners well, especially calm breeds like the Great Dane, Newfoundland, and Bernese Mountain Dog. The key is choosing a breed known for an easygoing, trainable temperament rather than high drive or independence.

What is the easiest giant dog breed to train?

The Newfoundland and Bernese Mountain Dog are widely considered the easiest giant breeds to train. Both are eager to please and respond well to positive reinforcement, making them solid choices for someone training their first dog.

How much does it cost to own a giant dog breed?

Giant breed owners often spend $80 to $150 a month on food alone, plus higher costs for vet care, medication doses, and pet supplies sized for a large dog. Total first-year costs often run higher than for a small or medium breed.

Do giant dog breeds need a lot of exercise?

Not always. Many giant breeds, including the Great Dane, Mastiff, and Saint Bernard, have low to moderate energy levels. The Alaskan Malamute is a clear exception and needs significant daily exercise to stay happy and well-behaved.

How long do giant dog breeds typically live?

Most giant breeds live 7 to 10 years, shorter than the 12 to 15 years common in smaller breeds. Some exceptions, like the Great Pyrenees and Akita, often live 10 to 13 years with good care.

Final Thoughts

Giant breeds aren’t automatically harder for a first-time owner. The real factor is temperament, not size. Pick a calm, trainable breed, start training early, and a giant dog can be one of the easiest, most rewarding first pets you’ll ever own.
