Arthritis Medications for Dogs and Cats: What Actually Works

By Dr Duncan Houston

Quick Answer

Arthritis in dogs and cats is best managed with a multimodal approach that combines anti-inflammatory medication, pain control, weight management, and joint support therapies. The most effective treatments typically include NSAIDs, targeted biologic injections, and supportive therapies, rather than relying on a single supplement or medication.

Understanding Arthritis in Pets

Osteoarthritis is the most common cause of chronic pain in dogs and cats.

It develops due to:

• joint instability or past injury

• abnormal joint development

• age-related cartilage breakdown

The key point is this:
arthritis is not just wear and tear. It is an active inflammatory disease.

That is why proper treatment focuses on both:

• reducing inflammation

• controlling pain

What Vets Actually Aim to Do

When treating arthritis, the goal is not just to “reduce pain.”

It is to:

• improve mobility

• slow progression

• maintain muscle strength

• preserve quality of life

This requires combining therapies, not relying on one solution.

The 5 Core Treatment Categories

1. Anti-Inflammatory Medications (Foundation of Treatment)

This is where most effective plans start.

NSAIDs reduce inflammation and pain directly at the source.

Common options include:

• carprofen

• meloxicam

• robenacoxib

• firocoxib

• deracoxib

• grapiprant (different mechanism, less traditional NSAID effect)

These are often the most impactful medications for improving comfort.

Important rule:
Never combine NSAIDs with steroids or other NSAIDs.

2. Additional Pain Modulators

Not all arthritis pain is inflammatory. Some is neurologic.

These drugs help with that component:

Gabapentin

• useful for nerve-related pain

• commonly used in both dogs and cats

• can cause sedation

Amantadine

• reduces chronic pain sensitization

• often used alongside NSAIDs

Tramadol

• limited effectiveness in dogs

• more useful in cats

These are typically added when NSAIDs alone are not enough.

3. Biologic and Injectable Therapies

This is one of the biggest advances in recent years.

Monoclonal antibodies

• target nerve growth factor (NGF)

• reduce pain signaling

• given as monthly injections

Examples:

• Librela for dogs

• Solensia for cats

These are:

• well tolerated

• effective for many patients

• suitable for long-term use

Polysulfated glycosaminoglycans

• support cartilage health

• reduce inflammation

Example:

• Adequan

4. Joint Support and Nutraceuticals

These can help, but expectations need to be realistic.

Glucosamine and chondroitin

• may support cartilage

• slow to show effect

Omega-3 fatty acids

• reduce inflammation

• one of the more evidence-supported supplements

Green-lipped mussel and other compounds

• mild anti-inflammatory effects

• variable response between patients

These are supportive, not primary treatments.

5. Regenerative and Advanced Therapies

Used in more complex or advanced cases.

Options include:

• platelet-rich plasma

• stem cell therapy

These aim to:

• support tissue repair

• improve joint environment

They can be beneficial, but:

• cost and access vary

• results are not guaranteed

The Most Important Factor: Weight

This is the most underestimated part of arthritis treatment.

Excess weight:

• increases joint load

• worsens inflammation

• reduces effectiveness of medications

Weight control alone can significantly improve mobility in many patients.

Exercise: Not Less, But Smarter

Complete rest is rarely the answer.

Better approach:

• controlled, low-impact exercise

• consistent movement

• avoiding sudden high-intensity activity

Muscle support protects joints.

What Vets Worry About Most

The biggest issues in arthritis management are:

• under-treating pain

• relying only on supplements

• missing early disease

• stopping medication too early

• ignoring weight and lifestyle factors

Arthritis is progressive. It needs ongoing management.

Common Mistakes Owners Make

Waiting until pain is severe

Early treatment improves long-term outcomes.

Avoiding NSAIDs out of fear

When used correctly, they are often the most effective tool.

Expecting supplements to replace medication

They rarely do.

Inconsistent treatment

Arthritis needs steady management, not occasional intervention.

Over-restricting movement

This leads to muscle loss and worse joint support.

What To Do Right Now

If your pet shows signs of arthritis:

1. Get a proper diagnosis

2. Start appropriate pain control

3. Address weight if needed

4. Introduce controlled exercise

5. Consider adding supportive therapies

If your pet is already diagnosed:

• reassess regularly

• adjust treatment as needed

• aim for consistent comfort, not temporary relief

Frequently Asked Questions

What is the best arthritis medication for dogs?

NSAIDs are usually the most effective first-line treatment.

What is the safest option for cats?

Options are more limited, but robenacoxib and monoclonal antibodies are commonly used.

Are injections better than tablets?

They can be, especially for long-term compliance and targeted action.

Do supplements actually work?

Some help, but they are not enough on their own.

Can arthritis be cured?

No, but it can be managed very effectively.

How quickly do medications work?

NSAIDs often work within days. Supplements take weeks.

Should I stop exercise?

No. Adjust it, but do not eliminate it.

Is weight really that important?

Yes. It is one of the most impactful factors.

When should I recheck my pet?

Regularly, especially if signs change or worsen.

Can older pets still improve?

Absolutely. Many respond very well to proper management.

Final Thoughts

Arthritis management has changed significantly.

The best outcomes now come from:

• combining therapies

• using the right medication early

• managing weight and movement

• reassessing regularly

It is no longer about one product.
It is about a structured plan.

When done properly, even older pets with arthritis can remain active, comfortable, and engaged for years.
