Arthritis in Great Danes: What Owners Need to Know

One of the hardest parts of sharing life with a Great Dane is watching them slow down.

Maybe they hesitate before standing up.

Maybe they take longer to climb the stairs.

Maybe they don't seem quite as excited about long walks as they once were.

Many owners assume these changes are simply part of getting older.

Sometimes they are.

But in many cases, arthritis may be playing a role.

Arthritis is one of the most common mobility challenges seen in aging dogs, particularly large and giant breeds like Great Danes. Understanding the signs, risk factors, and management strategies can help owners make informed decisions about their dog's long-term quality of life. For the bigger picture, see our Great Dane joint health guide.

What Is Arthritis?

Arthritis is a condition involving inflammation and degeneration within a joint.

The most common form in dogs is osteoarthritis, also known as degenerative joint disease.

Healthy joints contain smooth cartilage that helps bones move comfortably against one another.

Over time, cartilage can wear down, leading to changes within the joint that may affect movement, comfort, and function.

Arthritis is generally considered a progressive condition, meaning changes tend to accumulate over time.

Are Great Danes Prone to Arthritis?

Great Danes are not born with arthritis.

However, they are at increased risk for developing arthritis during their lifetime.

Several factors contribute to this risk.

Size and Weight

Most Great Danes weigh between 110 and 175 pounds.

That means their joints experience significant forces throughout their lives.

Joint Conditions

Conditions such as hip dysplasia and elbow dysplasia can increase the likelihood of arthritis developing later.

Previous Injuries

Joint injuries may contribute to long-term changes within affected joints.

Aging

As dogs age, normal wear and tear can contribute to joint degeneration.

Signs of Arthritis in Great Danes

Arthritis often develops gradually.

Many owners don't notice changes until they become more obvious.

Common signs include:

Difficulty Standing Up

Particularly after sleeping or resting.

Slower Movement

Taking longer to get moving during walks.

Hesitation on Stairs

Pausing before climbing or descending stairs.

Reluctance to Jump

Avoiding vehicles, furniture, or elevated surfaces.

Changes in Activity Levels

Sleeping more and moving less.

Altered Gait

Stiffness, shortened stride length, or uneven movement.

Changes in Behavior

Some dogs become less social, more withdrawn, or less interested in activities they previously enjoyed.

Because these changes often occur slowly, owners may mistakenly attribute them solely to aging.

How Common Is Arthritis in Dogs?

Arthritis is one of the most frequently diagnosed chronic conditions in dogs.

According to the American College of Veterinary Surgeons, osteoarthritis affects approximately 20% of dogs over one year of age, with prevalence increasing significantly in older and larger dogs. Additional statistics indicate 80% of dogs over the age of 8 will develp osteoarthritis. 

Large and giant breeds tend to be overrepresented in these statistics because of the increased stress placed on their joints over time.

How Is Arthritis Diagnosed?

Veterinarians typically diagnose arthritis through a combination of:

Physical Examination

Evaluating gait, mobility, and joint function.

Medical History

Reviewing symptoms and activity changes.

Radiographs (X-Rays)

Imaging can help identify changes within affected joints.

Mobility Assessments

Evaluating range of motion and comfort.

Early evaluation is important because many dogs show subtle signs long before owners realize mobility is changing.

Managing Arthritis in Great Danes

While arthritis cannot be reversed, there are many ways owners can help support their dog's mobility and quality of life.

Maintain a Healthy Weight

Weight management is often one of the most impactful factors in long-term mobility.

Every extra pound increases stress on already hard-working joints.

Preserve Muscle Mass

Strong muscles help support and stabilize joints.

Muscle loss is common as dogs age, making strength preservation an important part of mobility support. (Here's why muscle matters more than most owners realize.)

Encourage Appropriate Exercise

Movement remains important.

Consistent, low-impact activity is often preferable to long periods of inactivity followed by intense exercise.

Improve Traction at Home

Slippery floors can make movement more challenging.

Area rugs and runners often help improve confidence and stability.

Work With Your Veterinarian

Every dog is different.

Your veterinarian can help determine the most appropriate management strategies based on your dog's specific needs.

What About Joint Supplements?

Many Great Dane owners choose to include joint supplements as part of a comprehensive mobility support plan.

Joint supplements are typically intended to support normal joint function and healthy aging.

Common ingredients include:

• Glucosamine
• Chondroitin
• MSM
• Eggshell membrane
• Boswellia
• Antioxidants

Joint supplements are not intended to diagnose, treat, cure, or prevent any disease, including arthritis. They are intended to support normal joint function and overall wellness. If you'd like to understand the ingredients in more detail, our guide to what to look for in a joint supplement breaks them down.

Owners should discuss any supplement program with their veterinarian to determine what is appropriate for their individual dog.

Why We Focus on Mobility

At The Big Damn Dog Co., our mission is simple:

More, better years.

As Great Dane owners ourselves, we've experienced firsthand how important mobility is to quality of life.

The ability to comfortably join a walk. To get up easily from a favorite bed. To enjoy everyday adventures.

Those moments matter.

That's why we're passionate about helping giant breed owners learn about the many factors that influence mobility throughout a dog's life.

Frequently Asked Questions

At what age do Great Danes get arthritis?

There is no single age. Some dogs develop arthritis earlier due to genetics, injury, or underlying joint conditions, while others may not show signs until later in life.

Can arthritis be cured?

Arthritis is generally considered a progressive condition. Management focuses on supporting mobility, comfort, and quality of life.

Is arthritis common in Great Danes?

Yes. Great Danes are among the breeds at increased risk for mobility-related challenges because of their size and weight.

What are the first signs of arthritis in Great Danes?

Owners often notice slower movement, stiffness after rest, difficulty standing, hesitation on stairs, or reduced enthusiasm for physical activity.

The Bottom Line

Arthritis is one of the most common mobility challenges affecting Great Danes as they age.

While it can be difficult to watch your dog slow down, understanding the early signs and taking a proactive approach to mobility can help support quality of life throughout the aging process.

Because when you share your life with a Great Dane, every comfortable walk, every easy stand-up, and every extra adventure matters.
