What Is Considered a Giant Breed Dog?
Giant breed dogs are typically classified as dogs that weigh over 90–100 pounds at full maturity. Many of these dogs can easily exceed 120 pounds and stand several feet tall when on their hind legs.
Some common giant breeds include:
- Great Danes
- Saint Bernards
- Mastiffs
- Irish Wolfhounds
- Newfoundlands
While their size is the most obvious trait, it’s their slower growth rate, unique health considerations, and specific care needs that truly set them apart.
Temperament and Personality Traits
One of the biggest surprises for new pup parents is just how gentle and affectionate giant breed dogs can be. Many are often described as “gentle giants” for a reason.
These dogs tend to:
- Form deep bonds with their families
- Be calm and laid-back indoors
- Show patience with children (with proper supervision)
- Prefer companionship over independence
However, their size means even small behaviors, like jumping or pulling on leash, can become big problems if not addressed early.

Space and Lifestyle Considerations
Contrary to popular belief, giant breed dogs don’t always need acres of land, but they do need space to move comfortably.
Before adopting, ask yourself:
- Do I have enough room for a large dog to stretch out and relax?
- Can my home accommodate a large crate or bed?
- Am I okay with a dog that may take up most of the couch?
Apartment living isn’t impossible, but it requires intentional exercise, consistent routines, and a commitment to getting your dog outside regularly.

The Cost of Owning a Giant Breed
Giant dogs come with giant expenses; and it’s not just about food.
Here’s what typically costs more:
- Food (significantly higher daily intake)
- Vet care (medications and procedures often scale with weight)
- Supplies (beds, crates, harnesses, toys)
- Grooming (for long-coated breeds)
Even routine costs like flea/tick prevention and joint supplements are more expensive due to dosage requirements.
Nutrition and Feeding Needs
Nutrition is one of the most important factors in raising a healthy giant breed dog, especially during their growth phase.
These dogs require:
- Controlled growth to protect developing joints
- Balanced calcium and phosphorus levels
- High-quality protein for muscle development

Overfeeding or choosing the wrong diet can lead to serious issues like joint disorders or rapid growth complications.
That’s why many pup parents are turning to options like freeze-dried raw, which provide complete and balanced nutrition without the hassle of frozen storage or meal prep. A scoopable, shelf-stable formula, like Pupford’s Good Dog Food, can make feeding simpler while still supporting digestion, joints, and overall health.
Training and Socialization
Training a giant breed dog isn’t optional, it’s essential.
A 120-pound dog that pulls on leash or jumps on guests can quickly become overwhelming. The good news? Most giant breeds respond incredibly well to positive reinforcement training.
Focus on:
- Leash manners early
- Basic obedience (sit, stay, come, down)
- Impulse control (waiting at doors, calm greetings)
- Exposure to different environments and people
Consistency is key. Start training as early as possible, even in the first few days after bringing your dog home.

Health Considerations and Lifespan
One of the hardest realities of owning a giant breed dog is their shorter lifespan. Many giant breeds live between 7–10 years, though this can vary.
They’re also more prone to certain health issues, including:
- Joint problems (hip and elbow dysplasia)
- Bloat (gastric dilatation-volvulus)
- Heart conditions
- Arthritis
Preventative care plays a huge role here. Regular vet visits, proper nutrition, weight management, and appropriate exercise can make a significant difference in your dog’s quality of life.
Exercise and Joint Care
Giant breed dogs need daily exercise, but not excessive or high-impact activity, especially during puppyhood.
Too much stress on developing joints can lead to long-term damage.
Best practices include:
- Moderate daily walks
- Low-impact play (avoid excessive jumping)
- Mental enrichment activities
- Structured routines

As your dog ages, joint support becomes even more important. Keeping them at a healthy weight is one of the most effective ways to reduce strain on their body.

Grooming and Maintenance
Grooming needs vary depending on the breed, but all giant dogs come with one universal truth: everything is bigger.
That means:
- More shedding (and bigger fur piles)
- Larger baths
- Bigger nails to trim
- More drool (for some breeds)
Establish a grooming routine early so your dog becomes comfortable with handling.
Is a Giant Breed Dog Right for You?
