Equine Arthritis in Horses: Signs, Management and How to Support Long-Term Joint Health

Arthritis is one of the most common causes of stiffness and reduced performance in horses, especially as they age. But it doesn’t just affect veteran horses — competition horses, leisure horses and even younger horses can all experience joint wear and tear over time.

For many horse owners, the first signs are subtle. Your horse may feel stiffer when warming up, less willing to work, reluctant to pick up a certain lead, or slower to recover after exercise. These changes are often easy to dismiss as “getting older”, but they may indicate underlying joint discomfort.

The good news is that with early recognition, good management and the right nutritional support, many horses with arthritis can continue to enjoy comfortable, active lives.

What Is Equine Arthritis?

Arthritis, also known as osteoarthritis or degenerative joint disease, occurs when the cartilage within a joint gradually breaks down. Cartilage acts as a shock absorber between bones, allowing smooth movement. As this protective layer wears away, inflammation develops inside the joint, leading to stiffness, discomfort and reduced mobility.

Over time, the joint may become less flexible and everyday movement can become increasingly uncomfortable.

Arthritis commonly affects:

  • Hocks

  • Fetlocks

  • Knees

  • Coffin joints

  • Pastern joints

  • Stifles

While ageing is a major factor, arthritis can also develop due to:

  • Repetitive strain from exercise or competition

  • Previous injuries

  • Poor conformation

  • Excessive concussion on hard ground

  • Heavy workloads

  • Developmental joint issues

Signs of Arthritis in Horses

The signs of arthritis are not always dramatic in the early stages. Many horse owners notice small changes before obvious lameness develops.

Common signs include:

  • Stiffness when first moving

  • Difficulty bending or working evenly on both reins

  • Reluctance to jump or engage from behind

  • Reduced performance

  • Shortened stride

  • Swelling around joints

  • Heat in affected joints

  • Changes in behaviour during tacking up or ridden work

  • Difficulty standing after rest

  • Intermittent lameness

Cold weather can also make symptoms more noticeable, particularly in older horses.

Why Early Joint Support Matters

Joint damage cannot always be reversed, which is why supporting joint health early is so important.

Good management focuses on reducing inflammation, maintaining mobility and supporting the structures within the joint before severe degeneration develops.

This often includes:

  • Regular, appropriate exercise

  • Weight management

  • Supportive farriery

  • Comfortable turnout and bedding

  • Veterinary assessment where needed

  • Nutritional joint support

Many horse owners choose to introduce joint supplements before their horse shows significant signs of stiffness, particularly in performance horses or ageing horses.

Key Ingredients Commonly Used in Equine Joint Supplements

Modern equine joint supplements are designed to nutritionally support cartilage, joint fluid and the body’s natural inflammatory response.

Some of the most widely used ingredients include:

Glucosamine

Glucosamine is one of the best-known ingredients in equine joint supplements. It helps support cartilage structure and may assist in maintaining healthy joint function.

Chondroitin Sulphate

Chondroitin works alongside glucosamine and helps support cartilage elasticity and hydration.

MSM (Methylsulfonylmethane)

MSM provides a source of sulphur, which is important for connective tissue health. It is also commonly used to support comfort and mobility.

Hyaluronic Acid (HA)

Hyaluronic acid is a natural component of synovial fluid — the fluid that lubricates joints. Supporting healthy joint fluid can help maintain smoother movement.

Collagen and Amino Acids

Collagen forms part of the structural framework within cartilage and connective tissues.

Omega-3 Fatty Acids

Omega-3 fatty acids may help support the horse’s natural anti-inflammatory processes.

Boswellia and Botanical Ingredients

Some supplements include plant-based ingredients such as Boswellia or Devil’s Claw to help support comfort and mobility naturally.

Choosing the Right Joint Support for Your Horse

Not every horse needs the same level of support. The right product often depends on age, workload, previous injuries and the severity of stiffness.

For Younger or Competition Horses

Horses in regular work place significant stress on their joints, even before visible stiffness appears. Daily joint supplements containing glucosamine, MSM and hyaluronic acid are often used to support long-term joint health.

Products such as Hestevard BozMerix are commonly used to nutritionally support joint and muscular comfort in horses during periods of intense work, rehabilitation or age-related stiffness.

For Older Horses

Senior horses often benefit from more comprehensive support targeting mobility, inflammation and cartilage maintenance.

High-specification supplements containing glucosamine, chondroitin, MSM, hyaluronic acid and omega oils may help maintain comfort and quality of life.

For Horses Showing Signs of Stiffness

If your horse is already showing signs of reduced mobility, it is important to speak with your vet to identify the underlying cause.

Alongside veterinary guidance, many owners use nutritional support products as part of a broader management plan.

Management Tips for Horses with Arthritis

Arthritic horses often do best with consistent, sensible management.

Keep Them Moving

Regular low-impact exercise helps maintain joint mobility and muscle support around affected joints. Long periods of box rest can sometimes worsen stiffness.

Maintain a Healthy Weight

Excess body weight increases stress on joints. Keeping horses at an appropriate condition score can help reduce strain.

Warm Up Gradually

Older or arthritic horses may need longer warm-up periods before more demanding work.

Maximise Turnout

Gentle movement throughout the day often helps reduce stiffness compared to standing in for long periods.

Review Farriery

Correct hoof balance plays an important role in reducing joint strain.

Consider Joint Supplements Early

Many owners wait until stiffness becomes obvious before introducing support products. However, supporting joints proactively may help maintain long-term comfort and mobility.

Can Horses with Arthritis Still Be Ridden?

In many cases, yes.

Many horses with mild to moderate arthritis continue to enjoy ridden work, hacking or low-level competition with the right management plan.

The key is tailoring exercise to the individual horse and avoiding excessive strain.

Some horses benefit from:

  • Reduced jumping frequency

  • More hacking and straight-line work

  • Longer warm-ups and cool-downs

  • Softer surfaces

  • Lighter workloads during flare-ups

Always work closely with your vet if you suspect arthritis or if your horse’s mobility changes.

Supporting Your Horse for the Long Term

Arthritis is a common part of equine ageing and athletic wear and tear, but it does not necessarily mean the end of an active or enjoyable life.

Early recognition, sensible management and consistent joint support can make a significant difference to comfort and mobility over time.

Whether you own a competition horse, a happy hacker or a retired veteran, supporting joint health proactively can help your horse stay comfortable for longer.

Frequently Asked Questions About Equine Arthritis

What age do horses usually get arthritis?

Arthritis is more common in older horses, but younger horses can also develop joint issues due to workload, injuries or conformation.

Can joint supplements cure arthritis?

Joint supplements cannot cure arthritis, but they may help nutritionally support joint health, mobility and comfort as part of a wider management plan.

Should I stop riding a horse with arthritis?

Not always. Many horses with mild arthritis benefit from regular, controlled exercise. Your vet can advise what level of work is appropriate.

What is the best supplement for horse arthritis?

The best supplement depends on your horse’s age, workload and needs. Many owners look for products containing glucosamine, MSM, hyaluronic acid and chondroitin.

Does cold weather make arthritis worse in horses?

Many owners notice increased stiffness during colder weather, particularly in older horses or those with existing joint issues.
