Understanding Osteoarthritis in Dogs: Causes, Symptoms and How to Manage It

By nature, most dogs are full of energy and eager to chase balls, go on walks and zoom around the house. Osteoarthritis, a condition that affects an estimated one in five dogs over the age of one, can substantially limit those activities if not properly managed.

As a pet parent, understanding the causes, symptoms and treatment options for osteoarthritis in dogs is one of the most important things you can do for your dog’s long-term comfort.

What Is Osteoarthritis in Dogs?

Osteoarthritis (OA) in dogs, also called degenerative joint disease, is a progressive condition in which cartilage in the joints gradually breaks down, leading to pain, inflammation and reduced mobility.

While osteoarthritis cannot be reversed, consistent management including lifestyle adjustments and veterinarian-prescribed medication, is the foundation of long-term care for dogs with OA. For a clinical overview of the condition, the American College of Veterinary Surgeons provides a helpful reference.

How Common Is Osteoarthritis in Dogs?

Osteoarthritis is one of the most prevalent chronic conditions in dogs, and it starts earlier than most pet parents expect. According to Morris Animal Foundation, approximately 14 million adult dogs in the United States are currently affected. That translates to roughly one in five dogs over the age of one, with prevalence climbing sharply with age: the AKC Canine Health Foundation reports that approximately 80% of dogs over the age of eight show signs of the condition.

Because OA develops gradually and dogs often mask discomfort, many cases go undiagnosed longer than they should. Early detection gives veterinarians and pet parents the most options for intervention.

What Causes Osteoarthritis in Dogs?

Osteoarthritis develops when joint cartilage deteriorates faster than the body can repair it. Several factors increase a dog’s risk of developing OA:

• Age: The most common factor — senior dogs are at highest risk
• Genetics: Certain breeds, including Labrador Retrievers, German Shepherds and Golden Retrievers, are predisposed
• Obesity: Excess weight places added stress on joints
• Joint injuries: Prior trauma can accelerate cartilage breakdown
• Developmental disorders: Conditions such as hip dysplasia or elbow dysplasia increase long-term OA risk

A common misconception is that osteoarthritis only affects older dogs. In reality, large-breed dogs with developmental joint abnormalities can show signs of OA before age two. The American Kennel Club has additional guidance on breed-specific risk factors and early warning signs.

What Are the Symptoms of Osteoarthritis in Dogs?

Symptoms of osteoarthritis in dogs often appear gradually and may be more pronounced after rest or in cold weather. Common signs include:

• Limping or favoring one leg
• Reluctance to go on walks, climb stairs or jump
• Stiffness, especially after rest
• Difficulty rising from a lying position
• Behavioral changes such as increased irritability or reduced interest in play

If your dog shows any of these signs, schedule a veterinary examination. Your veterinarian can confirm a diagnosis through physical examination and imaging such as X-rays.

How Do Symptoms Change as Osteoarthritis Progresses?

OA symptoms typically intensify as the condition advances. The table below offers a general reference, but staging should always be determined by your veterinarian through a physical examination and imaging.

The Canine OsteoArthritis Staging Tool (COAST) is a validated framework veterinarians use to assess progression and guide treatment decisions.

How Can You Manage Osteoarthritis in Dogs at Home?

Managing osteoarthritis at home involves a combination of environmental adjustments and supportive care. Your veterinarian should guide the overall treatment plan. Home management is meant to complement, not replace, professional care.

Diet and Weight Management

Maintaining a healthy body weight is one of the most impactful steps a pet parent can take. Even modest weight reduction may help decrease mechanical stress on affected joints.

A diet that includes omega-3 fatty acids is sometimes discussed in the context of joint health — ask your veterinarian whether dietary adjustments make sense for your dog. For more information on nutrition and inflammation, see our guide on what to give your dog for inflammation.

Low-Impact Exercise

Short, consistent walks and swimming are generally well-tolerated by dogs with OA. High-impact activities like jumping or rough play can place added stress on affected joints and should be avoided.

Home Environment Modifications

• Use ramps or steps to help your dog access elevated surfaces such as beds, couches and vehicles
• Place non-slip mats or rugs on hard floors
• Provide an orthopedic dog bed to reduce pressure on joints during rest

Massage and Physical Therapy

Gentle massage is sometimes incorporated into supportive care routines. Ask your veterinarian about physical therapy exercises designed to maintain joint flexibility and muscle strength around affected joints.

Arthritis is also one of the most common conditions in senior dogs overall. Our guide to caring for a senior dog covers osteoarthritis alongside other age-related conditions.

What Do Veterinarians Prescribe for Osteoarthritis in Dogs?

For many dogs with moderate to severe osteoarthritis, lifestyle adjustments alone are not sufficient. Your veterinarian may prescribe a nonsteroidal anti-inflammatory drug (NSAID): the most established category of prescription medication indicated for osteoarthritis-related pain and inflammation in dogs.

An important note: Human NSAIDs such as ibuprofen and acetaminophen are toxic to dogs and should never be given without explicit veterinary guidance. Only medications formulated and prescribed specifically for dogs are appropriate.

Firocoxib Chewable Tablets

Your veterinarian may prescribe Previcox (Firocoxib) Chewable Tablets, a COX-2 selective NSAID indicated for the control of pain and inflammation associated with osteoarthritis in dogs. Available in a chewable formulation, it is typically given once daily, with or without food.

Firocoxib is available by prescription only. All NSAID therapy requires veterinary oversight, including baseline bloodwork and periodic monitoring to assess liver and kidney function. Your veterinarian will determine whether it is appropriate based on your dog’s individual health profile, including any history of gastrointestinal, kidney or liver concerns.

Depending on your dog’s profile, other NSAIDs may also be considered. Carprofen (Rimadyl) is another frequently prescribed option, as is meloxicam for dogs. Medication selection, dosing and monitoring are always determined by your veterinarian.

Frequently Asked Questions About Osteoarthritis in Dogs

What is osteoarthritis in dogs?

Osteoarthritis in dogs is a progressive joint condition caused by the gradual breakdown of cartilage in one or more joints, leading to pain, inflammation and reduced mobility. Also called degenerative joint disease, it is one of the most common chronic conditions in dogs, affecting an estimated one in five dogs over the age of one.

What are the early signs of osteoarthritis in dogs?

Early signs include subtle changes in gait, reluctance to rise or climb stairs, mild stiffness after rest and decreased enthusiasm for physical activity. Many pet parents attribute these signs to normal aging. A veterinarian can evaluate whether OA is a contributing factor through a physical examination and, if needed, imaging.

Can young dogs get osteoarthritis?

Yes. While osteoarthritis is more common in older dogs, younger dogs can develop it — particularly large-breed dogs with genetic predispositions, developmental joint disorders such as hip or elbow dysplasia or a history of joint injuries.

What is the best treatment for osteoarthritis in dogs?

There is no single best treatment. Management of osteoarthritis in dogs is typically multimodal. Your veterinarian may recommend a combination of prescription NSAIDs, weight management, low-impact exercise and supportive care. Medication selection depends on your dog's individual health history.

Is walking good for dogs with osteoarthritis?

In most cases, yes. Short, consistent low-impact walks are generally appropriate for dogs with OA. High-impact activities like jumping or rough play should be avoided. Your veterinarian can advise on the right frequency and duration for your dog's specific condition and stage.

Can I give my dog human pain relievers for arthritis?

No. Medications such as ibuprofen and acetaminophen are toxic to dogs and can cause serious harm, including gastrointestinal ulcers, kidney injury and in severe cases, death. Always consult your veterinarian before giving your dog any medication, prescription or over-the-counter.
